Member Function Documentation

GetPipeline() [1/4]

virtual PipelineFuture<ComputePipelineDescriptor> impeller::PipelineLibrary::GetPipeline ( ComputePipelineDescriptor  descriptor, bool  async = true  )

pure virtual

GetPipeline() [2/4]

virtual PipelineFuture<PipelineDescriptor> impeller::PipelineLibrary::GetPipeline ( PipelineDescriptor  descriptor, bool  async = true, bool  threadsafe = false  )

pure virtual

Creates a pipeline.

Parameters

[in]	descriptor	The descriptor of the texture to create.
[in]	async	Whether to allow pipeline creation to be deferred. If false, pipeline creation will block on the current thread.
[in]	threadsafe	Whether mutations to this texture should be protected with a threadsafe barrier.

This parameter only affects the OpenGLES rendering backend.

If any interaction with this texture (including creation) will be done on a thread other than where the OpenGLES context resides, then threadsafe, must be set to true.
