## ◆ GetCachedFrameData()

const FramebufferAndRenderPass & impeller::TextureVK::GetCachedFrameData | ( | SampleCount | sample_count | ) | const

Retrieve the last framebuffer and render pass object used with this texture.

An empty FramebufferAndRenderPass is returned if there is no cached data for a particular sample count.

## ◆ SetCachedFrameData()

void impeller::TextureVK::SetCachedFrameData | ( | const FramebufferAndRenderPass & | data,
|  | SampleCount | sample_count

Store the last framebuffer and render pass object used with this texture.

This method is only called if this texture is used as the resolve texture of a render pass. By construction, this framebuffer should be compatible with any future render passes.
