Public Member Functions | |
HardwareUniformBuffer (HardwareBufferManagerBase *mgr, size_t sizeBytes, HardwareBuffer::Usage usage, bool useShadowBuffer=false, const String &name="") | |
Should be called by HardwareBufferManager. | |
~HardwareUniformBuffer () | |
HardwareBufferManagerBase * | getManager () const |
const String & | getName () const |
![]() | |
HardwareBuffer (Usage usage, bool systemMemory, bool useShadowBuffer) | |
Constructor, to be called by HardwareBufferManager only. | |
virtual | ~HardwareBuffer () |
virtual void | _updateFromShadow (void) |
Updates the real buffer from the shadow buffer, if required. | |
virtual 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. | |
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)=0 |
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. | |
virtual void | unlock (void) |
Releases the lock on this buffer. | |
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. | |
