| void | setBuffer (void *buffer, size_t size) |
| Request that the buffer object manage an existing block of memory. | |
| virtual SoBufferObject * | createInstance () const |
| Create a new buffer with the same properties as the current one. | |
| virtual void | clearInstance () |
| This function clears the content of the buffer, it frees the memory if the mode was COPY. | |
| Public Member Functions inherited from SoBufferObject | |
| void | lockBuffer () |

| void | unlockBuffer () |
| Unlocks the buffer object. | |
| virtual bool | setSize (size_t size) |
| Sets the size in bytes of the buffer object. | |
| virtual size_t | getSize () const |
| Returns the size, in bytes, of the buffer object. | |
| virtual void * | map (AccessMode accessMode, size_t offset=0, size_t count=SO_BUFFER_SIZE_ALL) |
| Map the buffer to a system memory address and allows the mapping of a sub part of the buffer object into CPU memory. | |
| virtual void | unmap () |
| Unmaps the buffer from CPU address space. | |
| virtual void | map (SoBufferObject *targetBufferObject, AccessMode accessMode, size_t startPosition=0, size_t mappingSize=SO_BUFFER_SIZE_ALL) |
| Maps the current buffer object into the specified buffer object. | |
| virtual void | unmap (SoBufferObject *bufferObject) |
| Unmap this buffer from the specified buffer object. | |
| virtual void | memcpy (SoBufferObject *sourceBufferObject, size_t destOffset=0, size_t sourceOffset=0, size_t copySize=SO_BUFFER_SIZE_ALL) |
| Copies data from the specified buffer object into this buffer object. | |
| virtual void | memset (void *value, size_t valueSize=1, size_t offset=0, size_t count=SO_BUFFER_SIZE_ALL) |
| This function sets the contents of (or a portion of) this buffer object to the specified value. | |
| SoDeviceContext * | getContext () const |
| Returns the device context where this buffer is valid. | |
| SoBufferObject * | getMappedBufferObject () const |
| Returns a pointer to the buffer object which is mapped by the actual object. | |

| void | ref () const |
| Adds a reference to an instance. | |
| void | unref () const |
| Removes a reference from an instance. | |
| void | unrefNoDelete () const |
| unrefNoDelete() should be called when it is desired to decrement the reference count, but not delete the instance if this brings the reference count to zero. | |
| int | getRefCount () const |
| Returns current reference count. | |
| void | lock () const |
| lock this instance. | |
| void | unlock () const |
| unlock this instance. | |
