| size_t | getInstanceDataStepRate () const |
| Get the number of instances to draw using the same per-instance data before advancing in the buffer by one element. More... | |
| bool | getIsInstanceData () const |
| Get if this vertex buffer is an "instance data" buffer (per instance) More... | |
| HardwareBufferManagerBase * | getManager () const |
| Return the manager of this buffer, if any. More... | |
| size_t | getNumVertices () const |
| Get the number of vertices in this buffer. More... | |
| size_t | getVertexSize () const |
| Gets the size in bytes of a single vertex in this buffer. More... | |
| void | setInstanceDataStepRate (const size_t val) |
| Set the number of instances to draw using the same per-instance data before advancing in the buffer by one element. More... | |
| void | setIsInstanceData (const bool val) |

| Public Member Functions inherited from Ogre::v1::HardwareBuffer | |
| HardwareBuffer (Usage usage, bool systemMemory, bool useShadowBuffer) | |
| Constructor, to be called by HardwareBufferManager only. More... | |
| virtual | ~HardwareBuffer () |
| virtual void | _updateFromShadow () |
| Updates the real buffer from the shadow buffer, if required. More... | |
| virtual 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... | |
| virtual void * | getRenderSystemData () |
| An internal function that should be used only by a render system for internal use. More... | |
| size_t | getSizeInBytes () const |
| Returns the size of this buffer in bytes. More... | |
| Usage | getUsage () const |
| Returns the Usage flags with which this buffer was created. More... | |
| bool | hasShadowBuffer () const |
| Returns whether this buffer has a system memory shadow for quicker reading. More... | |
| bool | isLocked () const |
| Returns whether or not this buffer is currently locked. More... | |
| bool | isSystemMemory () const |
| Returns whether this buffer is held in system memory. More... | |
| void * | lock (LockOptions options) |
| Lock the entire buffer for (potentially) reading / writing. More... | |
| virtual void * | lock (size_t offset, size_t length, LockOptions options) |
| Lock the buffer for (potentially) reading / writing. More... | |
| virtual void | readData (size_t offset, size_t length, void *pDest)=0 |
| Reads data from the buffer and places it in the memory pointed to by pDest. More... | |
| void | suppressHardwareUpdate (bool suppress) |
| Pass true to suppress hardware upload of shadow buffer changes. More... | |
| virtual void | unlock () |
| Releases the lock on this buffer. More... | |
| virtual void | writeData (size_t offset, size_t length, const void *pSource, bool discardWholeBuffer=false)=0 |
| Writes data to the buffer from an area of system memory; note that you must ensure that your buffer is big enough. More... | |
