ARBShaderObjects (LWJGL 3.2.4 SNAPSHOT

java.lang.Object
- org.lwjgl.opengl.ARBShaderObjects

```
public class ARBShaderObjects
extends java.lang.Object
```
Native bindings to the ARB_shader_objects extension.
This extension adds API calls that are necessary to manage shader objects and program objects as defined in the OpenGL 2.0 white papers by 3Dlabs.

The generation of an executable that runs on one of OpenGL's programmable units is modeled to that of developing a typical C/C++ application. There are one or more source files, each of which are stored by OpenGL in a shader object. Each shader object (source file) needs to be compiled and attached to a program object. Once all shader objects are compiled successfully, the program object needs to be linked to produce an executable. This executable is part of the program object, and can now be loaded onto the programmable units to make it part of the current OpenGL state. Both the compile and link stages generate a text string that can be queried to get more information. This information could be, but is not limited to, compile errors, link errors, optimization hints, etc. Values for uniform variables, declared in a shader, can be set by the application and used to control a shader's behavior.

This extension defines functions for creating shader objects and program objects, for compiling shader objects, for linking program objects, for attaching shader objects to program objects, and for using a program object as part of current state. Functions to load uniform values are also defined. Some house keeping functions, like deleting an object and querying object state, are also provided.

Although this extension defines the API for creating shader objects, it does not define any specific types of shader objects. It is assumed that this extension will be implemented along with at least one such additional extension for creating a specific type of OpenGL 2.0 shader (e.g., the ARB_fragment_shader extension or the ARB_vertex_shader extension).

Promoted to core in OpenGL 2.0.

Method Detail

glDeleteObjectARB
```
public static void glDeleteObjectARB(int obj)
```
Either deletes the object, or flags it for deletion. An object that is attached to a container object is not deleted until it is no longer attached to any container object, for any context. If it is still attached to at least one container object, the object is flagged for deletion. If the object is part of the current rendering state, it is not deleted until it is no longer part of the current rendering state for any context. If the object is still part of the rendering state of at least one context, it is flagged for deletion.
If an object is flagged for deletion, its Boolean status bit OBJECT_DELETE_STATUS_ARB is set to true.

DeleteObjectARB will silently ignore the value zero.

When a container object is deleted, it will detach each attached object as part of the deletion process. When an object is deleted, all information for the object referenced is lost. The data for the object is also deleted.

Parameters:

obj - the shader object to delete

glGetHandleARB
```
public static int glGetHandleARB(int pname)
```
Returns the handle to an object that is in use as part of current state.

Parameters:

pname - the state item for which the current object is to be returned. Must be:
PROGRAM_OBJECT_ARB

glDetachObjectARB
```
public static void glDetachObjectARB(int containerObj,
                                     int attachedObj)
```
Detaches an object from the container object it is attached to.

Parameters:

containerObj - the container object

attachedObj - the object to detach

glCreateShaderObjectARB
```
public static int glCreateShaderObjectARB(int shaderType)
```
Creates a shader object.

Parameters:

shaderType - the type of the shader object to be created. One of:

                                     @Nullable
                                     java.nio.IntBuffer length)
```
Sets the source code for the specified shader object shaderObj to the text strings in the string array. If the object previously had source code loaded into it, it is completely replaced.
The strings that are loaded into a shader object are expected to form the source code for a valid shader as defined in the OpenGL Shading Language Specification.

Parameters:

shaderObj - the shader object

string - an array of pointers to one or more, optionally null terminated, character strings that make up the source code

length - an array with the number of charARBs in each string (the string length). Each element in this array can be set to negative one (or smaller), indicating that its accompanying string is null terminated. If length is set to NULL, all strings in the string argument are considered null terminated.

glShaderSourceARB
```
public static void glShaderSourceARB(int shaderObj,
                                     java.lang.CharSequence... string)
```
Sets the source code for the specified shader object shaderObj to the text strings in the string array. If the object previously had source code loaded into it, it is completely replaced.
The strings that are loaded into a shader object are expected to form the source code for a valid shader as defined in the OpenGL Shading Language Specification.

Parameters:

shaderObj - the shader object

string - an array of pointers to one or more, optionally null terminated, character strings that make up the source code

glShaderSourceARB
```
public static void glShaderSourceARB(int shaderObj,
                                     java.lang.CharSequence string)
```
Sets the source code for the specified shader object shaderObj to the text strings in the string array. If the object previously had source code loaded into it, it is completely replaced.
The strings that are loaded into a shader object are expected to form the source code for a valid shader as defined in the OpenGL Shading Language Specification.

Parameters:

shaderObj - the shader object

string - an array of pointers to one or more, optionally null terminated, character strings that make up the source code

glCompileShaderARB
```
public static void glCompileShaderARB(int shaderObj)
```
Compiles a shader object. Each shader object has a Boolean status, OBJECT_COMPILE_STATUS_ARB, that is modified as a result of compilation. This status can be queried with GetObjectParameterivARB. This status will be set to TRUE if the shader shaderObj was compiled without errors and is ready for use, and FALSE otherwise. Compilation can fail for a variety of reasons as listed in the OpenGL Shading Language Specification. If CompileShaderARB failed, any information about a previous compile is lost and is not restored. Thus a failed compile does not restore the old state of shaderObj. If shaderObj does not reference a shader object, the error INVALID_OPERATION is generated.
Note that changing the source code of a shader object, through ShaderSourceARB, does not change its compile status OBJECT_COMPILE_STATUS_ARB.

Each shader object has an information log that is modified as a result of compilation. This information log can be queried with GetInfoLogARB to obtain more information about the compilation attempt.

Parameters:

shaderObj - the shader object to compile

glCreateProgramObjectARB
```
public static int glCreateProgramObjectARB()
```
Creates a program object.
A program object is a container object. Shader objects are attached to a program object with the command AttachObjectARB. It is permissible to attach shader objects to program objects before source code has been loaded into the shader object, or before the shader object has been compiled. It is permissible to attach multiple shader objects of the same type to a single program object, and it is permissible to attach a shader object to more than one program object.

glAttachObjectARB
```
public static void glAttachObjectARB(int containerObj,
                                     int obj)
```
Attaches an object to a container object.

Parameters:

containerObj - the container object

obj - the object to attach

glLinkProgramARB
```
public static void glLinkProgramARB(int programObj)
```
Links a program object.
Each program object has a Boolean status, OBJECT_LINK_STATUS_ARB, that is modified as a result of linking. This status can be queried with GetObjectParameterivARB. This status will be set to TRUE if a valid executable is created, and FALSE otherwise. Linking can fail for a variety of reasons as specified in the OpenGL Shading Language Specification. Linking will also fail if one or more of the shader objects, attached to programObj, are not compiled successfully, or if more active uniform or active sampler variables are used in programObj than allowed. If LinkProgramARB failed, any information about a previous link is lost and is not restored. Thus a failed link does not restore the old state of programObj. If programObj is not of type PROGRAM_OBJECT_ARB, the error INVALID_OPERATION is generated.

Each program object has an information log that is modified as a result of a link operation. This information log can be queried with GetInfoLogARB to obtain more information about the link operation.

Parameters:

programObj - the program object to link

glUseProgramObjectARB
```
public static void glUseProgramObjectARB(int programObj)
```
Installs the executable code as part of current rendering state if the program object programObj contains valid executable code, i.e. has been linked successfully. If UseProgramObjectARB is called with the handle set to 0, it is as if the GL had no programmable stages and the fixed functionality paths will be used instead. If programObj cannot be made part of the current rendering state, an INVALID_OPERATION error will be generated and the current rendering state left unmodified. This error will be set, for example, if programObj has not been linked successfully. If programObj is not of type PROGRAM_OBJECT_ARB, the error INVALID_OPERATION is generated.
While a program object is in use, applications are free to modify attached shader objects, compile attached shader objects, attach additional shader objects, and detach shader objects. This does not affect the link status OBJECT_LINK_STATUS_ARB of the program object. This does not affect the executable code that is part of the current state either. That executable code is only affected when the program object has been re-linked successfully. After such a successful re-link, the LinkProgramARB command will install the generated executable code as part of the current rendering state if the specified program object was already in use as a result of a previous call to UseProgramObjectARB. If this re-link failed, then the executable code part of the current state does not change.

Parameters:

programObj - the program object to use

glValidateProgramARB
```
public static void glValidateProgramARB(int programObj)
```
Validates the program object programObj against the GL state at that moment. Each program object has a Boolean status, OBJECT_VALIDATE_STATUS_ARB, that is modified as a result of validation. This status can be queried with GetObjectParameterivARB. If validation succeeded this status will be set to TRUE, otherwise it will be set to FALSE. If validation succeeded the program object is guaranteed to execute, given the current GL state. If validation failed, the program object is guaranteed to not execute, given the current GL state. If programObj is not of type PROGRAM_OBJECT_ARB, the error INVALID_OPERATION is generated.
ValidateProgramARB will validate at least as much as is done when a rendering command is issued, and it could validate more. For example, it could give a hint on how to optimize some piece of shader code.

ValidateProgramARB will store its information in the info log. This information will either be an empty string or it will contain validation information.

ValidateProgramARB is typically only useful during application development. An application should not expect different OpenGL implementations to produce identical information.

Parameters:

programObj - the program object to validate

                                   java.nio.ByteBuffer infoLog)
```
A string that contains information about the last link or validation attempt and last compilation attempt are kept per program or shader object. This string is called the info log and can be obtained with this command.
This string will be null terminated. The number of characters in the info log is given by OBJECT_INFO_LOG_LENGTH_ARB, which can be queried with GetObjectParameterivARB. If obj is a shader object, the returned info log will either be an empty string or it will contain information about the last compilation attempt for that object. If obj is a program object, the returned info log will either be an empty string or it will contain information about the last link attempt or last validation attempt for that object. If obj is not of type PROGRAM_OBJECT_ARB or SHADER_OBJECT_ARB, the error INVALID_OPERATION is generated. If an error occurred, the return parameters length and infoLog will be unmodified.

The info log is typically only useful during application development and an application should not expect different OpenGL implementations to produce identical info logs.

Parameters:

obj - the shader object to query

length - the actual number of characters written by the GL into infoLog is returned in length, excluding the null termination. If length is NULL then the GL ignores this parameter.

infoLog - a buffer in which to return the info log

glGetInfoLogARB
```
public static java.lang.String glGetInfoLogARB(int obj,
                                               int maxLength)
```
A string that contains information about the last link or validation attempt and last compilation attempt are kept per program or shader object. This string is called the info log and can be obtained with this command.
This string will be null terminated. The number of characters in the info log is given by OBJECT_INFO_LOG_LENGTH_ARB, which can be queried with GetObjectParameterivARB. If obj is a shader object, the returned info log will either be an empty string or it will contain information about the last compilation attempt for that object. If obj is a program object, the returned info log will either be an empty string or it will contain information about the last link attempt or last validation attempt for that object. If obj is not of type PROGRAM_OBJECT_ARB or SHADER_OBJECT_ARB, the error INVALID_OPERATION is generated. If an error occurred, the return parameters length and infoLog will be unmodified.

The info log is typically only useful during application development and an application should not expect different OpenGL implementations to produce identical info logs.

Parameters:

obj - the shader object to query

maxLength - the maximum number of characters the GL is allowed to write into infoLog

glGetUniformLocationARB
```
public static int glGetUniformLocationARB(int programObj,
                                          java.nio.ByteBuffer name)
```
Returns the location of uniform variable name. name has to be a null terminated string, without white space. The value of -1 will be returned if name does not correspond to an active uniform variable name in programObj or if name starts with the reserved prefix "gl_". If programObj has not been successfully linked, or if programObj is not of type PROGRAM_OBJECT_ARB, the error INVALID_OPERATION is generated. The location of a uniform variable does not change until the next link command is issued.
A valid name cannot be a structure, an array of structures, or a subcomponent of a vector or a matrix. In order to identify a valid name, the "." (dot) and "[]" operators can be used in name to operate on a structure or to operate on an array.

The first element of a uniform array is identified using the name of the uniform array appended with "[0]". Except if the last part of the string name indicates a uniform array, then the location of the first element of that array can be retrieved by either using the name of the uniform array, or the name of the uniform array appended with "[0]".

Parameters:

programObj - the program object to query

name - the name of the uniform variable whose location is to be queried

glGetUniformLocationARB

                                         java.nio.ByteBuffer name)
```
Determines which of the declared uniform variables are active and their sizes and types.
This command provides information about the uniform selected by index. The index of 0 selects the first active uniform, and index of OBJECT_ACTIVE_UNIFORMS_ARB - 1 selects the last active uniform. The value of OBJECT_ACTIVE_UNIFORMS_ARB can be queried with GetObjectParameterivARB. If index is greater than or equal to OBJECT_ACTIVE_UNIFORMS_ARB, the error INVALID_VALUE is generated.

If an error occurred, the return parameters length, size, type and name will be unmodified.

The returned uniform name can be the name of built-in uniform state as well. The length of the longest uniform name in programObj is given by OBJECT_ACTIVE_UNIFORM_MAX_LENGTH_ARB, which can be queried with GetObjectParameterivARB.

Each uniform variable, declared in a shader, is broken down into one or more strings using the "." (dot) and "[]" operators, if necessary, to the point that it is legal to pass each string back into GetUniformLocationARB. Each of these strings constitutes one active uniform, and each string is assigned an index.

If one or more elements of an array are active, GetActiveUniformARB will return the name of the array in name, subject to the restrictions listed above. The type of the array is returned in type. The size parameter contains the highest array element index used, plus one. The compiler or linker determines the highest index used. There will be only one active uniform reported by the GL per uniform array.

This command will return as much information about active uniforms as possible. If no information is available, length will be set to zero and name will be an empty string. This situation could arise if GetActiveUniformARB is issued after a failed link.

Parameters:

programObj - a handle to a program object for which the command LinkProgramARB has been issued in the past. It is not necessary for programObj to have been linked successfully. The link could have failed because the number of active uniforms exceeded the limit.

index - the uniform index

length - a buffer in which to return the actual number of characters written by the GL into name. This count excludes the null termination. If length is NULL then the GL ignores this parameter.

size - a buffer in which to return the uniform size. The size is in units of the type returned in type.

type - a buffer in which to return the uniform type

name - a buffer in which to return the uniform name
