Inheritance diagram for Ogre::GLHardwareVertexBuffer:

Public Member Functions
	GLHardwareVertexBuffer (GLenum target, size_t sizeInBytes, Usage usage, bool useShadowBuffer)

	~GLHardwareVertexBuffer ()

void	_updateFromShadow (void) override
	See HardwareBuffer. More...

GLuint	getGLBufferId (void) const

void	readData (size_t offset, size_t length, void *pDest) override
	See HardwareBuffer. More...

void	writeData (size_t offset, size_t length, const void *pSource, bool discardWholeBuffer=false) override
	See HardwareBuffer. More...

Public Member Functions inherited from Ogre::HardwareBuffer
	HardwareBuffer (Usage usage, bool systemMemory, bool useShadowBuffer)
	Constructor, to be called by HardwareBufferManager only. More...

virtual	~HardwareBuffer ()

template<typename T >
T *	_getImpl ()

void	copyData (HardwareBuffer &srcBuffer)
	Copy all data from another buffer into this one. More...

virtual void	copyData (HardwareBuffer &srcBuffer, size_t srcOffset, size_t dstOffset, size_t length, bool discardWholeBuffer=false)
	Copy data from another buffer into this one. More...

size_t	getSizeInBytes (void) const
	Returns the size of this buffer in bytes. More...

Usage	getUsage (void) const
	Returns the Usage flags with which this buffer was created. More...

bool	hasShadowBuffer (void) const
	Returns whether this buffer has a system memory shadow for quicker reading. More...

bool	isLocked (void) const
	Returns whether or not this buffer is currently locked. More...

bool	isSystemMemory (void) const
	Returns whether this buffer is held in system memory. More...

void *	lock (LockOptions options)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. More...

virtual void *	lock (size_t offset, size_t length, LockOptions options)
	Lock the buffer for (potentially) reading / writing. More...

void	suppressHardwareUpdate (bool suppress)
	Pass true to suppress hardware upload of shadow buffer changes. More...

void	unlock (void)
	Releases the lock on this buffer. More...
