on_iteration_barrier()

void MayaFlux::Buffers::ClaimFlattenProcessor::on_iteration_barrier ( Portal::Graphics::CommandBufferID  cmd_id, const std::shared_ptr< VKBuffer > &  buffer, uint32_t  index  )

overrideprotectedvirtual

Called after each iteration except the last.

Parameters

cmd_id	Command buffer being recorded into.
buffer	Buffer under processing.
index	Zero-based index of the iteration just recorded.

Default issues a compute-to-compute buffer_barrier on the attached buffer's own handle. Override when the hazard is on resources the attached buffer does not own, such as raw double-buffered state.

Reimplemented from MayaFlux::Buffers::ComputeProcessor.
