unsigned int GetBufferHandle() const override
Return handle to the vertex buffer.
bool IsMapped() const override
Return true if vertex buffer is currently mapped.
Class to store VERTEX instances with caching.
CACHED_CONTAINER_RAM(unsigned int aSize=DEFAULT_SIZE)
Specialization of CACHED_CONTAINER that stores data in RAM.
static constexpr unsigned int DEFAULT_SIZE
~CACHED_CONTAINER_RAM()
Finish the vertices updates stage.
bool defragmentResize(unsigned int aNewSize) override
Defragment the currently stored data and resizes the buffer.
void Unmap() override
Finish the vertices updates stage.
void Map() override
Finish the vertices updates stage.
