Method Summary

Modifier and Type	Method	Description
void	formatToGLCapabilities(GLCapabilities caps, boolean rgba8Avail)	Writes the internal format to the given GLCapabilities object.
void	free(GL gl)	Releases the color buffer if initialized, i.e.
FBObject.ColorAttachment	getColorAttachment()	Casts this object to a FBObject.ColorAttachment reference, see isTextureAttachment().
int	getFormat()	internal format of colorbuffer
int	getHeight()	height of colorbuffer
int	getName()	colorbuffer name [1..max]
FBObject.TextureAttachment	getTextureAttachment()	Casts this object to a FBObject.TextureAttachment reference, see isTextureAttachment().
int	getWidth()	width of colorbuffer
boolean	initialize(GL gl)	Initializes the color buffer and set it's parameter, if uninitialized, i.e.
boolean	isTextureAttachment()	Returns true if instance is of type FBObject.TextureAttachment and false if instance is of type FBObject.ColorAttachment.

Method Detail

initialize

boolean initialize(GL gl)
            throws GLException

Initializes the color buffer and set it's parameter, if uninitialized, i.e. name is zero.

Returns:

true if newly initialized, otherwise false.

Throws:

GLException - if buffer generation or setup fails. The just created buffer name will be deleted in this case.

free

void free(GL gl)
   throws GLException

Releases the color buffer if initialized, i.e. name is not zero.

Throws:

GLException - if buffer release fails.

formatToGLCapabilities

void formatToGLCapabilities(GLCapabilities caps,
                            boolean rgba8Avail)

Writes the internal format to the given GLCapabilities object.

Parameters:

caps - the destination for format bits

rgba8Avail - whether rgba8 is available

isTextureAttachment

boolean isTextureAttachment()

Returns true if instance is of type FBObject.TextureAttachment and false if instance is of type FBObject.ColorAttachment.

getTextureAttachment

FBObject.TextureAttachment getTextureAttachment()

Casts this object to a FBObject.TextureAttachment reference, see isTextureAttachment().

Throws:

GLException - if this object is not of type FBObject.TextureAttachment

See Also:

isTextureAttachment()

getColorAttachment

FBObject.ColorAttachment getColorAttachment()

Casts this object to a FBObject.ColorAttachment reference, see isTextureAttachment().

Throws:

GLException - if this object is not of type FBObject.ColorAttachment

See Also:

isTextureAttachment()

getFormat

int getFormat()

internal format of colorbuffer

getWidth

int getWidth()

width of colorbuffer

getHeight

int getHeight()

height of colorbuffer

getName

int getName()

colorbuffer name [1..max]
