Field Detail

programString

protected java.lang.String programString

The program string that is stored as the shader

protected boolean programChanged

Flag to say that the string has changed and should be recompiled

programId

protected int programId

The ID of the shader program that has been allocated here

Constructor Detail

GL14ShaderProgram

public GL14ShaderProgram()

Constructs a Shader with default values.

Method Detail

setProgramString

public void setProgramString(java.lang.String str)
                      throws InvalidWriteTimingException

Set the program string that is to be registered by this shader. Setting a value of null will clear the current shader and prevent it from being rendered next frame.

Parameters:

str - The new program string to be registered or null

Throws:

InvalidWriteTimingException - An attempt was made to write outside of the NodeUpdateListener callback method

getProgramString

public java.lang.String getProgramString()

Get the currently set program string. If none is set, return null.

Returns:

The current string or null
