Class BufferObject

java.lang.Object
  com.threerings.opengl.renderer.BufferObject

public class BufferObject
extends Object

An OpenGL buffer object.

Field Summary

protected int	_bytes The current size of the buffer, in bytes.
protected int	_id The OpenGL identifier for this buffer.
protected Renderer	_renderer The renderer that loaded this buffer.

Constructor Summary

protected	BufferObject() Creates an invalid buffer object (used by the renderer to force reapplication).
	BufferObject(Renderer renderer) Creates a new buffer object for the specified renderer.

Method Summary

void	delete() Deletes this buffer object, rendering it unusable.
protected void	finalize()
int	getId() Returns this buffer's OpenGL identifier.
protected void	setBytes(int bytes) Notes the size of the buffer (and notifies the renderer).
void	setData(FloatBuffer data) Sets the data in this buffer.
void	setData(FloatBuffer data, int usage) Sets the data in this buffer.
void	setData(long size) Initializes the data in this buffer.
void	setData(long size, int usage) Initializes the data in this buffer.
void	setData(ShortBuffer data) Sets the data in this buffer.
void	setData(ShortBuffer data, int usage) Sets the data in this buffer.
void	setSubData(long offset, FloatBuffer data) Sets part of the data in this buffer.
void	setSubData(long offset, ShortBuffer data) Sets part of the data in this buffer.
