ObjCRuntime (LWJGL 3.2.4 SNAPSHOT

java.lang.Object
- org.lwjgl.system.macosx.ObjCRuntime

```
public class ObjCRuntime
extends java.lang.Object
```
Native bindings to the Objective-C Runtime.
Due to the nature of the objc_msgSend* functions, they are not directly exposed in this binding. Advanced users with good understanding of the complexity involved with using these functions, may access them via the getLibrary() method:
```
 SharedLibrary objc = ObjCRuntime.getLibrary();
 long objc_msgSend = objc.getFunctionAddress("objc_msgSend");
 
 // example usage
 long NSThread = objc_getClass("NSThread");
 long currentThread = invokePPP(NSThread, sel_getUid("currentThread"), objc_msgSend);
```
The safe way to use objc_msgSend in C code is to cast it to an appropriate function pointer. This is exactly what the JNI class does. If a particular function signature is not available, DynCall may be used to invoke it.

The functions not exposed are:
- objc_msgSend
- objc_msgSend_stret
- objc_msgSendSuper
- objc_msgSendSuper_stret

  - object_getIndexedIvars
```
public static long object_getIndexedIvars(long obj)
```
    This function returns a pointer to any extra bytes allocated with the instance (as specified by class_createInstance(long, long) with extraBytes>0). This memory follows the object's ordinary ivars, but may not be adjacent to the last ivar.
    The returned pointer is guaranteed to be pointer-size aligned, even if the area following the object's last ivar is less aligned than that. Alignment greater than pointer-size is never guaranteed, even if the area following the object's last ivar is more aligned than that.
    
    In a garbage-collected environment, the memory is scanned conservatively.
    
    Parameters:
    
    obj - an Objective-C object
    
    Returns:
    
    a pointer to any extra bytes allocated with obj. If obj was not allocated with any extra bytes, then dereferencing the returned pointer is undefined.
  - object_getIvar

    Reads the value of an instance variable in an object.
    
    Parameters:
    
    obj - the object containing the instance variable whose value you want to read
    
    ivar - the Ivar describing the instance variable whose value you want to read
    
    Returns:
    
    the value of the instance variable specified by ivar, or nil if obj is nil
  - object_setIvar

```
    Sets the value of an instance variable in an object.
    object_setIvar is faster than object_setInstanceVariable(long, java.nio.ByteBuffer, java.nio.ByteBuffer) if the Ivar for the instance variable is already known.
    
    Parameters:
    
    obj - the object containing the instance variable whose value you want to set
    
    ivar - the Ivar describing the instance variable whose value you want to set
    
    value - the new value for the instance variable

public static long nobjc_getClass(long name)
```
    Unsafe version of: objc_getClass(java.nio.ByteBuffer)
  - objc_getClass
```
public static long objc_getClass(java.nio.ByteBuffer name)
```
    Returns the class definition of a specified class.
    objc_getClass is different from objc_lookUpClass(java.nio.ByteBuffer) in that if the class is not registered, objc_getClass calls the class handler callback and then checks a second time to see whether the class is registered. objc_lookUpClass does not call the class handler callback.
    
    Parameters:
    
    name - the name of the class to look up
    
    Returns:
    
    the Class object for the named class, or nil if the class is not registered with the Objective-C runtime
  - objc_getClass
```
public static long objc_getClass(java.lang.CharSequence name)

  - objc_getMetaClass
```
public static long objc_getMetaClass(java.nio.ByteBuffer name)
```
    Returns the metaclass definition of a specified class.
    If the definition for the named class is not registered, this function calls the class handler callback and then checks a second time to see if the class is registered. However, every class definition must have a valid metaclass definition, and so the metaclass definition is always returned, whether it’s valid or not.
    
    Parameters:
    
    name - the name of the class to look up
    
    Returns:
    
    the Class object for the metaclass of the named class, or nil if the class is not registered with the Objective-C runtime

  - objc_getRequiredClass
```
public static long objc_getRequiredClass(java.nio.ByteBuffer name)
```
    Returns the class definition of a specified class.
    This function is the same as objc_getClass(java.nio.ByteBuffer), but kills the process if the class is not found.
    
    This function is used by ZeroLink, where failing to find a class would be a compile-time link error without ZeroLink.
    
    Parameters:
    
    name - the name of the class to look up
    
    Returns:
    
    the Class object for the named class
  - objc_getRequiredClass

  - nobjc_getClassList
```
public static int nobjc_getClassList(long buffer,
                                     int bufferCount)
```
    Unsafe version of: objc_getClassList(org.lwjgl.PointerBuffer)
    
    Parameters:
    
    bufferCount - the number of pointers for which you have allocated space in buffer. On return, this function fills in only this number of elements. If this number is less than the number of registered classes, this function returns an arbitrary subset of the registered classes.
  - objc_getClassList
```
public static int objc_getClassList(@Nullable
                                    org.lwjgl.PointerBuffer buffer)
```
    Obtains the list of registered class definitions.
    The Objective-C runtime library automatically registers all the classes defined in your source code. You can create class definitions at runtime and register them with the objc_allocateClassPair(long, java.nio.ByteBuffer, long) and objc_registerClassPair(long) functions.
    
    Special Considerations
    
    You cannot assume that class objects you get from this function are classes that inherit from NSObject, so you cannot safely call any methods on such classes without detecting that the method is implemented first.
    
    Parameters:
    
    buffer - an array of Class values. On output, each Class value points to one class definition, up to either bufferCount or the total number of registered classes, whichever is less. You can pass NULL to obtain the total number of registered class definitions without actually retrieving any class definitions.
    
    Returns:
    
    an integer value indicating the total number of registered classes
  - nobjc_copyClassList
```
public static long nobjc_copyClassList(long outCount)
```
    Unsafe version of: objc_copyClassList()
    
    Parameters:
    
    outCount - an integer pointer used to store the number of classes returned by this function in the list. This parameter may be nil
  - objc_copyClassList
```
@Nullable
public static org.lwjgl.PointerBuffer objc_copyClassList()
```
    Creates and returns a list of pointers to all registered class definitions.
    
    Returns:
    
    a nil terminated array of classes. You must free the array with free()
  - nclass_getName
```
public static long nclass_getName(long cls)
```
    Unsafe version of: class_getName(long)
  - class_getName
```
@Nullable
public static java.lang.String class_getName(long cls)
```
    Returns the name of a class.
    
    Parameters:
    
    cls - a class object
    
    Returns:
    
    the name of the class, or the empty string if cls is Nil
  - class_isMetaClass
```
public static boolean class_isMetaClass(long cls)
```
    Returns a Boolean value that indicates whether a class object is a metaclass.
    
    Parameters:
    
    cls - a class object
    
    Returns:
    
    YES if cls is a metaclass, NO if cls is a non-meta class, NO if cls is Nil
  - class_getSuperclass
```
public static long class_getSuperclass(long cls)
```
    Returns the superclass of a class.
    
    Parameters:
    
    cls - a class object
    
    Returns:
    
    the superclass of the class, or Nil if cls is a root class, or Nil if cls is Nil
  - class_getVersion
```
public static int class_getVersion(long cls)
```
    Returns the version number of a class definition.
    You can use the version number of the class definition to provide versioning of the interface that your class represents to other classes. This is especially useful for object serialization (that is, archiving of the object in a flattened form), where it is important to recognize changes to the layout of the instance variables in different class-definition versions.
    
    Classes derived from the Foundation framework NSObject class can obtain the class-definition version number using the getVersion class method, which is implemented using the class_getVersion function.
    
    Parameters:
    
    cls - a pointer to an Class data structure. Pass the class definition for which you wish to obtain the version
    
    Returns:
    
    an integer indicating the version number of the class definition
  - class_setVersion
```
public static void class_setVersion(long cls,
                                    int version)
```
    Sets the version number of a class definition.

    Classes derived from the Foundation framework NSObject class can set the class-definition version number using the setVersion: class method, which is implemented using the class_setVersion function.
    
    Parameters:
    
    cls - a pointer to an Class data structure. Pass the class definition for which you wish to set the version
    
    version - the new version number of the class definition
  - class_getInstanceSize
```
public static long class_getInstanceSize(long cls)
```
    Returns the size of instances of a class.
    
    Parameters:
    
    cls - a class object
    
    Returns:
    
    the size in bytes of instances of the class cls, or 0 if cls is Nil

    Parameters:
    
    cls - the class you want to inspect
    
    name - the selector of the method you want to retrieve
    
    Returns:
    
    the method that corresponds to the implementation of the selector specified by aSelector for the class specified by cls, or NULL if the specified class or its superclasses do not contain an instance method with the specified selector.
  - class_getClassMethod
```
public static long class_getClassMethod(long cls,
                                        long name)
```
    Returns a pointer to the data structure describing a given class method for a given class.
    Note that this function searches superclasses for implementations, whereas class_copyMethodList(long) does not.
    
    Parameters:
    
    cls - a pointer to a class definition. Pass the class that contains the method you want to retrieve
    
    name - a pointer of type SEL. Pass the selector of the method you want to retrieve
    
    Returns:
    
    a pointer to the Method data structure that corresponds to the implementation of the selector specified by name for the class specified by cls, or NULL if the specified class or its superclasses do not contain a class method with the specified selector.
  - class_getMethodImplementation
```
public static long class_getMethodImplementation(long cls,
                                                 long name)
```
    Returns the function pointer that would be called if a particular message were sent to an instance of a class.
    class_getMethodImplementation may be faster than method_getImplementation(class_getInstanceMethod(cls, name)).
    
    The function pointer returned may be a function internal to the runtime instead of an actual method implementation. For example, if instances of the class do not respond to the selector, the function pointer returned will be part of the runtime's message forwarding machinery.
    
    Parameters:
    
    cls - the class you want to inspect
    
    name - a selector
    
    Returns:

```
    Returns a Boolean value that indicates whether instances of a class respond to a particular selector.
    You should usually use NSObject's respondsToSelector: or instancesRespondToSelector: methods instead of this function.
    
    Parameters:

```
    Adds a new method to a class with a given name and implementation.
    Discussion
    
    class_addMethod will add an override of a superclass's implementation, but will not replace an existing implementation in this class. To change an existing implementation, use method_setImplementation(long, long).
    
    An Objective-C method is simply a C function that takes at least two arguments – self and _cmd. For example, given the following function:
```
 void myMethodIMP(id self, SEL _cmd)
 {
     // implementation ....
 }
```
    you can dynamically add it to a class as a method (called resolveThisMethodDynamically) like this:
```
 class_addMethod([self class], @selector(resolveThisMethodDynamically), (IMP) myMethodIMP, "v@:");
```
    Parameters:
    
    cls - the class to which to add a method
    
    name - a selector that specifies the name of the method being added
    
    imp - a function which is the implementation of the new method. The function must take at least two arguments – self and _cmd.
    
    types - an array of characters that describe the types of the arguments to the method. For possible values, see Objective-C Runtime Programming Guide > Type Encodings in Objective-C Runtime Programming Guide. Since the function must take at least two arguments – self and _cmd, the second and third characters must be “@:” (the first character is the return type).
    
    Returns:
    
    YES if the method was added successfully, otherwise NO (for example, the class already contains a method implementation with that name)
  - class_addMethod

    Parameters:
    
    cls - the class you want to modify
    
    name - a selector that identifies the method whose implementation you want to replace

    The instance variable's minimum alignment in bytes is 1<<align. The minimum alignment of an instance variable depends on the ivar's type and the machine architecture. For variables of any pointer type, pass log2(sizeof(pointer_type)).
    
    Returns:
    
    YES if the instance variable was added successfully, otherwise NO (for example, the class already contains an instance variable with that name)

Then set the class's attributes with functions like class_addMethod(long, long, long, java.nio.ByteBuffer) and class_addIvar(long, java.nio.ByteBuffer, long, byte, java.nio.ByteBuffer). When you are done building the class, call objc_registerClassPair(long). The new class is now ready for use.
    
    Instance methods and instance variables should be added to the class itself. Class methods should be added to the metaclass.
    
    Parameters:
    
    superclass - the class to use as the new class's superclass, or Nil to create a new root class
    
    name - the string to use as the new class's name. The string will be copied.
    
    extraBytes - the number of bytes to allocate for indexed ivars at the end of the class and metaclass objects. This should usually be 0.
    
    Returns:
    
    the new class, or Nil if the class could not be created (for example, the desired name is already in use)

Then set the class's attributes with functions like class_addMethod(long, long, long, java.nio.ByteBuffer) and class_addIvar(long, java.nio.ByteBuffer, long, byte, java.nio.ByteBuffer). When you are done building the class, call objc_registerClassPair(long). The new class is now ready for use.
    
    Instance methods and instance variables should be added to the class itself. Class methods should be added to the metaclass.
    
    Parameters:
    
    superclass - the class to use as the new class's superclass, or Nil to create a new root class

```
    Adds a property to a protocol that is under construction.
    The protocol you want to add the property to must be under construction – allocated but not yet registered with the Objective-C runtime (via the objc_registerProtocol(long) function).
    
    Parameters:
    
    proto - the protocol you want to add a property to
    
    name - the name of the property you want to add.
    
    attributes - an array of property attributes
    
    isRequiredProperty - a Boolean indicating whether the property's accessor methods are required methods of the proto protocol. If YES, the property's accessor methods are required methods; if NO, the property's accessor methods are optional methods.
    
    isInstanceProperty - a Boolean indicating whether the property's accessor methods are instance methods. If YES, the property's accessor methods are instance methods. YES is the only value allowed for a property. As a result, if you set this value to NO, the property will not be added to the protocol.

  - objc_enumerationMutation
```
public static void objc_enumerationMutation(long obj)
```
    Inserted by the compiler when a mutation is detected during a foreach iteration.
    The compiler inserts this function when it detects that an object is mutated during a foreach iteration. The function is called when a mutation occurs, and the enumeration mutation handler is enacted if it is set up (via the objc_setEnumerationMutationHandler(org.lwjgl.system.macosx.EnumerationMutationHandlerI) function). If the handler is not set up, a fatal error occurs.
    
    Parameters:
    
    obj - the object being mutated
  - nobjc_setEnumerationMutationHandler
```
public static void nobjc_setEnumerationMutationHandler(long handler)
```

```
public static void objc_setEnumerationMutationHandler(EnumerationMutationHandlerI handler)
```
    Sets the current mutation handler.
    
    Parameters:
    
    handler - a function pointer to the new mutation handler
  - imp_implementationWithBlock
```
public static long imp_implementationWithBlock(long block)
```
    Creates a pointer to a function that calls the specified block when the method is called.
    
    Parameters:
    
    block - the block that implements this method. The signature of block should be method_return_type ^(id self, self, method_args …). The selector of the method is not available to block. block is copied with Block_copy().
    
    Returns:
    
    the IMP that calls block. You must dispose of the returned IMP using the function.
  - imp_getBlock
```
public static long imp_getBlock(long anImp)
```
    Returns the block associated with an IMP that was created using imp_implementationWithBlock(long).

    Parameters:
    
    anImp - an IMP that was created using the imp_implementationWithBlock(long) function.
    
    Returns:
    
    YES if the block was released successfully; otherwise, NO (for example, the function returns NO if the block was not used to create anImp previously).

                                 org.lwjgl.PointerBuffer location)
```
    Loads the object referenced by a weak pointer and returns it.
    This function loads the object referenced by a weak pointer and returns it after retaining and autoreleasing the object. As a result, the object stays alive long enough for the caller to use it. This function is typically used anywhere a __weak variable is used in an expression.
    
    Parameters:
    
    location - the address of the weak pointer
    
    Returns:
    
    the object pointed to by location, or nil if location is nil
  - nobjc_storeWeak
```
public static long nobjc_storeWeak(long location,
                                   long obj)

```
    Stores a new value in a __weak variable.
    This function is typically used anywhere a __weak variable is the target of an assignment.
    
    Parameters:
    
    location - the address of the weak pointer
    
    obj - the new object you want the weak pointer to now point to
    
    Returns:
    
    the value stored in location (that is, obj)
  - objc_setAssociatedObject
```
public static void objc_setAssociatedObject(long object,
                                            long key,
                                            long value,
                                            long policy)
```
    Sets an associated value for a given object using a given key and association policy.
    
    Parameters:
    
    object - the source object for the association
    
    key - the key for the association
    
    value - the value to associate with the key key for object. Pass nil to clear an existing association.
    
    policy - the policy for the association. One of:
    OBJC_ASSOCIATION_ASSIGN OBJC_ASSOCIATION_RETAIN_NONATOMIC OBJC_ASSOCIATION_COPY_NONATOMIC
    OBJC_ASSOCIATION_RETAIN OBJC_ASSOCIATION_COPY
  - objc_getAssociatedObject
```
public static long objc_getAssociatedObject(long object,
                                            long key)
```
    Returns the value associated with a given object for a given key.
    
    Parameters:
    
    object - the source object for the association
    
    key - the key for the association
    
    Returns:
    
    the value associated with the key key for object.
  - objc_removeAssociatedObjects
```
public static void objc_removeAssociatedObjects(long object)
```
    Removes all associations for a given object.
    The main purpose of this function is to make it easy to return an object to a "pristine state". You should not use this function for general removal of associations from objects, since it also removes associations that other clients may have added to the object. Typically you should use objc_setAssociatedObject(long, long, long, long) with a nil value to clear an association.
    
    Parameters:
    
    object - an object that maintains associated objects
