Member Function Documentation

getDataPtr()

void * Ogre::v1::GLES2DefaultHardwareUniformBuffer::getDataPtr ( size_t  offset ) const

inline

lock()

void * Ogre::v1::GLES2DefaultHardwareUniformBuffer::lock	(	size_t	offset,
		size_t	length,
		LockOptions	options
	)

Override HardwareBuffer to turn off all shadowing.

readData()

void Ogre::v1::GLES2DefaultHardwareUniformBuffer::readData	(	size_t	offset,
		size_t	length,
		void *	pDest
	)

Reads data from the buffer and places it in the memory pointed to by pDest.

Parameters

offset	The byte offset from the start of the buffer to read
length	The size of the area to read, in bytes
pDest	The area of memory in which to place the data, must be large enough to accommodate the data!

unlock()

void Ogre::v1::GLES2DefaultHardwareUniformBuffer::unlock

(

)

Override HardwareBuffer to turn off all shadowing.

writeData()

void Ogre::v1::GLES2DefaultHardwareUniformBuffer::writeData	(	size_t	offset,
		size_t	length,
		const void *	pSource,
		bool	discardWholeBuffer = false
	)

Writes data to the buffer from an area of system memory; note that you must ensure that your buffer is big enough.

Parameters

offset	The byte offset from the start of the buffer to start writing
length	The size of the data to write to, in bytes
pSource	The source of the data to be written
discardWholeBuffer	If true, this allows the driver to discard the entire buffer when writing, such that DMA stalls can be avoided; use if you can.
