Member Function Documentation

CreateTexture()

std::shared_ptr< Texture > impeller::RenderTargetAllocator::CreateTexture ( const TextureDescriptor &  desc )

virtual

Create a new render target texture, or recycle a previously allocated render target texture.

Reimplemented in impeller::testing::TestRenderTargetAllocator, and impeller::RenderTargetCache.

Definition at line 25 of file render_target.cc.

                                   {
  return allocator_->CreateTexture(desc);
}

End()

void impeller::RenderTargetAllocator::End ( )

virtual

Mark the end of a frame workload.

   This may be used to deallocate any unused textures. 

Reimplemented in impeller::testing::TestRenderTargetAllocator, and impeller::RenderTargetCache.

Definition at line 23 of file render_target.cc.

{}

Referenced by impeller::testing::TestRenderTargetAllocator::End().

Start()

void impeller::RenderTargetAllocator::Start ( )

virtual

Mark the beginning of a frame workload.

  This may be used to reset any tracking state on whether or not a
  particular texture instance is still in use. 

Reimplemented in impeller::testing::TestRenderTargetAllocator, and impeller::RenderTargetCache.
