Member Data Documentation

bOutputFromDDC

bool FShaderJobData::bOutputFromDDC

Track which code path wrote this output, for tracking down a bug

DuplicateJobsWaitList

FShaderCommonCompileJob* FShaderJobData::DuplicateJobsWaitList = nullptr

Head of a linked list of duplicate jobs

InputHash

FShaderCompilerInputHash FShaderJobData::InputHash

JobInFlight

FShaderCommonCompileJobPtr FShaderJobData::JobInFlight

In-flight job with the given input hash. Needs to be a reference pointer to handle cancelling of jobs, where an async DDC query (which receives a pointer to FShaderJobData) may be in-flight that still references a job that has otherwise been deleted. Cancelled jobs will have been unlinked from the PendingSubmitJobTaskJobs list in RemoveAllPendingJobsWithId, which can be detected in the callback, and further processing on the job skipped.

OutputHash

FJobOutputHash FShaderJobData::OutputHash

Output hash will be zero if output data has not been written yet, or can be cleared if output data has been removed
