Enumerator
StorageBuffer	Memory barrier for Buffer resources that were created with the BindFlags::Storage bind flags. Remarks Shader access to the buffer will reflect all data written to by previous shaders. See also BindFlags::Storage
StorageTexture	Memory barrier for Texture resources that were created with the BindFlags::Storage bind flags. Remarks Shader access to the texture will reflect all data written to by previous shaders. See also BindFlags::Storage
Storage	Memory barrier for any storage resource. This is just a bitwise OR combination of StorageBuffer and StorageTexture. Remarks Renderer backends such as Direct3D 12 and Vulkan have bookkeeping for storage resources and don't have to distinguish between Buffer and Texture resource views for their barriers at time of creating the ResourceHeap. Hence, using BarrierFlags::Storage by default when any resource views in the ResourceHeap have to be synchronized is recommended. Only the OpenGL backend has to know at creation time what type of resources need a global barrier via glMemoryBarrier. See also BindFlags::Storage
