Syntax
struct FShaderJobCacheRef
Remarks
Cached reference to the location of an in-flight job's FShaderJobData in the FShaderJobDataMap, used by the private FShaderJobCache class.
Caching the reference avoids the need to do additional map lookups to find the entry again, potentially avoiding a lock of the container for the lookup. Heap allocation of blocks is used by the cache to allow map entries to have a persistent location in memory. The persistent memory allows modifications of map entry data for a given job, without needing locks to protect against container resizing.
In-flight jobs and their duplicates reference the same FShaderJobData. Client code should treat this structure as opaque.
