 Inheritance diagram for Ogre::DefaultHardwareBuffer:| Public Member Functions | |
| DefaultHardwareBuffer (size_t sizeInBytes) | |
| ~DefaultHardwareBuffer () | |
| bool | isSystemMemory (void) const override | 
| Returns whether this buffer is held in system memory. | |
| void | readData (size_t offset, size_t length, void *pDest) override | 
| Reads data from the buffer and places it in the memory pointed to by pDest. | |
| void | writeData (size_t offset, size_t length, const void *pSource, bool discardWholeBuffer=false) override | 
| Writes data to the buffer from an area of system memory; note that you must ensure that your buffer is big enough. | |
|  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. | |
| 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. | |
| void | suppressHardwareUpdate (bool suppress) | 
| Pass true to suppress hardware upload of shadow buffer changes. | |
| void | unlock (void) | 
| Releases the lock on this buffer. | |

| Ogre::DefaultHardwareBuffer::~DefaultHardwareBuffer | ( | ) | 
| 
 | overridevirtual | 
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! | 
Reimplemented from Ogre::HardwareBuffer.
| 
 | overridevirtual | 
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. | 
Reimplemented from Ogre::HardwareBuffer.
| 
 | inlineoverridevirtual | 
Returns whether this buffer is held in system memory.
