## Constructor & Destructor Documentation

## ◆ RenderTargetAllocator()

impeller::RenderTargetAllocator::RenderTargetAllocator | ( | std::shared_ptr< Allocator > | allocator | ) |
| explicit

Definition at line 17 of file render_target.cc.

19 : allocator_(std::move(allocator)) {}

## ◆ ~RenderTargetAllocator()

virtual impeller::RenderTargetAllocator::~RenderTargetAllocator | ( |  | ) |
| virtual default

## 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.

26 {
27 return allocator_->CreateTexture(desc);
28 }

Referenced by impeller::RenderTarget::CreateOffscreen(), impeller::RenderTarget::CreateOffscreenMSAA(), impeller::RenderTargetCache::CreateTexture(), impeller::testing::TestRenderTargetAllocator::CreateTexture(), and impeller::RenderTarget::SetupStencilAttachment().

## ◆ 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.

23 {}

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.

Definition at line 21 of file render_target.cc.

21 {}
