Constructor Detail

ShaderProgram

public ShaderProgram()

Method Detail

linked

public boolean linked()

inUse

public boolean inUse()

program

public int program()

id

public int id()

returns the uniq shader id as an integer

See Also:

key()

key

public Integer key()

returns the uniq shader id as an Integer

See Also:

id()

destroy

public void destroy(GL2ES2 gl)

Detaches all shader codes and deletes the program. Destroys the shader codes as well. Calls release(gl, true)

See Also:

release(GL2ES2, boolean)

release

public void release(GL2ES2 gl)

Detaches all shader codes and deletes the program. Calls release(gl, false)

See Also:

release(GL2ES2, boolean)

release

public void release(GL2ES2 gl,
                    boolean releaseShaderToo)

Detaches all shader codes and deletes the program. If releaseShaderToo is true, destroys the shader codes as well.

add

public boolean add(ShaderCode shaderCode)

Adds a new shader to a this non running program.

Returns:

false if the program is in use, or the shader already exist, otherwise true.

getShader

public ShaderCode getShader(int id)

glReplaceShader

public boolean glReplaceShader(GL2ES2 gl,
                               int oldShaderID,
                               ShaderCode newShader,
                               PrintStream verboseOut)

Replace a shader in a 'running' program. Refetches all previously bin/get attribute names and resets all attribute data as well

Parameters:

gl -

oldShaderID - the to be replace Shader

newShader - the new ShaderCode

verboseOut - the optional verbose outputstream

Throws:

GLException - is the program is not linked
