Field Summary

static int	FRAGMENT_SHADER The component represents a fragment shader
static int	GEOMETRY_SHADER The component represents a geometry shader
static int	PROGRAM_SHADER The component represents a complete GLSL shader program
static int	VERTEX_SHADER The component represents a vertex shader

Method Summary

int	getComponentType() Get the type of component this state represents.
int	getProgramId(javax.media.opengl.GL gl) Fetch the ID handle for this program for the given context.
boolean	isValid(javax.media.opengl.GL gl) Check to see if this is linked for the given GL context.
void	reinitialize(javax.media.opengl.GL gl) Re-initialise this shader because the underlying GL context has changed.

Method Detail

getComponentType

int getComponentType()

Get the type of component this state represents.

Returns:

One of the _SHADER constants

isValid

boolean isValid(javax.media.opengl.GL gl)

Check to see if this is linked for the given GL context. This tests to see if a valid program ID has already been assigned, indicating that at least an internal link(gl) call has been made.

Parameters:

gl - The GL context to test for linkage against

Returns:

true if there is a valid ID to work with

getProgramId

int getProgramId(javax.media.opengl.GL gl)

Fetch the ID handle for this program for the given context.

Parameters:

gl - The GL context to get the ID for

Returns:

The ID value or 0 if none

reinitialize

void reinitialize(javax.media.opengl.GL gl)

Re-initialise this shader because the underlying GL context has changed. This should also reinitialise any resources that it is dependent on.

Parameters:

gl - The GL context to reinitialise with
