Inheritance diagram for Ogre::HardwareUniformBuffer:Public Member Functions | |
| HardwareUniformBuffer (HardwareBufferManagerBase *mgr, HardwareBuffer *delegate) | |
| HardwareUniformBuffer (HardwareBufferManagerBase *mgr, size_t sizeBytes, HardwareBuffer::Usage usage, bool useShadowBuffer=false, const String &name="") | |
| Should be called by HardwareBufferManager. More... | |
| ~HardwareUniformBuffer () | |
| HardwareBufferManagerBase * | getManager () const |
| const String & | getName () const |
| Public Member Functions inherited from Ogre::HardwareBuffer | |
| HardwareBuffer (Usage usage, bool systemMemory, bool useShadowBuffer) | |
| Constructor, to be called by HardwareBufferManager only. More... | |
| virtual | ~HardwareBuffer () |
| template<typename T > | |
| T * | _getImpl () |
| virtual void | _updateFromShadow (void) |
| Updates the real buffer from the shadow buffer, if required. More... | |
| 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... | |
| size_t | getSizeInBytes (void) const |
| Returns the size of this buffer in bytes. More... | |
| Usage | getUsage (void) const |
| Returns the Usage flags with which this buffer was created. More... | |
| bool | hasShadowBuffer (void) const |
| Returns whether this buffer has a system memory shadow for quicker reading. More... | |
| bool | isLocked (void) const |
| Returns whether or not this buffer is currently locked. More... | |
| bool | isSystemMemory (void) const |
| Returns whether this buffer is held in system memory. More... | |
| 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. 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) |
| 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... | |
| void | unlock (void) |
| Releases the lock on this buffer. More... | |
| 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. More... | |
Additional Inherited Members | |
| Public Types inherited from Ogre::HardwareBuffer | |
| enum | LockOptions { HBL_NORMAL, HBL_DISCARD, HBL_READ_ONLY, HBL_NO_OVERWRITE, HBL_WRITE_ONLY } |
| Locking options. More... | |
| typedef int | Usage |
| enum | UsageEnum { HBU_STATIC = HBU_GPU_TO_CPU, HBU_DYNAMIC = HBU_CPU_ONLY, HBU_WRITE_ONLY = HBU_DETAIL_WRITE_ONLY, HBU_DISCARDABLE = 8, HBU_STATIC_WRITE_ONLY = HBU_GPU_ONLY, HBU_DYNAMIC_WRITE_ONLY = HBU_CPU_TO_GPU, HBU_DYNAMIC_WRITE_ONLY_DISCARDABLE = HBU_CPU_TO_GPU } |
