virtual |
Reads data from the buffer and places it in the memory pointed to by pDest.
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! |
Implements Ogre::HardwareBuffer.

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

inlinevirtualinherited |
Copy data from another buffer into this one.
srcBuffer | The buffer from which to read the copied data |
srcOffset | Offset in the source buffer at which to start reading |
dstOffset | Offset in the destination buffer to start writing |
length | Length of the data to copy, in bytes. |
discardWholeBuffer | If true, will discard the entire contents of this buffer before copying |
