Syntax

class FRHITransientHeap

Remarks

The base class for a platform heap implementation. Transient resources are placed on the heap at specific byte offsets. Each heap additionally contains a cache of RHI transient resources, each with its own RHI resource and cache of RHI views. The lifetime of the resource cache is tied to the heap.
