class FOpenGLUniformBuffer : public FRHIUniformBuffer

Type	Name	Description
uint32	AllocatedSize	The size of the buffer allocated to hold the uniform buffer contents. May be larger than necessary.
bool	bIsEmulatedUniformBuffer	True if the uniform buffer is emulated
bool	bOwnsResource	True if Resource belongs to this UniformBuffer
bool	bStreamDraw	True if the uniform buffer is not used across frames.
FOpenGLEUniformBufferDataRef	EmulatedBufferData	Emulated uniform data for ES2.
uint32	Offset	The offset of the uniform buffer's contents in the resource.
uint8 *	PersistentlyMappedBuffer	When using a persistently mapped buffer this is a pointer to the CPU accessible data.
uint32	RangeSize	The data range size of uniform buffer's contents in the resource.
GLuint	Resource	The GL resource for this uniform buffer.
uint32	UniqueID	Unique ID for state shadowing purposes.
