Public Member Functions inherited from Ogre::HardwareBuffer | |
| HardwareBuffer (Usage usage, bool useShadowBuffer) | |
| Constructor, to be called by HardwareBufferManager only. | |
| virtual | ~HardwareBuffer () |
| template<typename T> | |
| T * | _getImpl () |
| virtual void | _updateFromShadow (void) |
| Updates the real buffer from the shadow buffer, if required. | |
| void | copyData (HardwareBuffer &srcBuffer) |
| Copy all data from another buffer into this one. | |
| 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. | |
| size_t | getSizeInBytes (void) const |
| Returns the size of this buffer in bytes. | |
| Usage | getUsage (void) const |
| Returns the Usage flags with which this buffer was created. | |
| bool | hasShadowBuffer (void) const |
| Returns whether this buffer has a system memory shadow for quicker reading. | |
| bool | isLocked (void) const |
| Returns whether or not this buffer is currently locked. | |
| virtual bool | isSystemMemory (void) const |
| Returns whether this buffer is held in system memory. | |
| 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. | |
| virtual void * | lock (size_t offset, size_t length, LockOptions options) |
| Lock the buffer for (potentially) reading / writing. | |
| virtual void | readData (size_t offset, size_t length, void *pDest) |
| Reads data from the buffer and places it in the memory pointed to by pDest. | |
| void | suppressHardwareUpdate (bool suppress) |
| Pass true to suppress hardware upload of shadow buffer changes. | |
| void | unlock (void) |
| Releases the lock on this buffer. | |
| virtual void | 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. | |
