◆ CreateCommandBuffer()

std::shared_ptr< impeller::CommandBuffer > flutter::testing::android::TestImpellerContext::CreateCommandBuffer ( ) const
inlineoverridevirtual

Create a new command buffer. Command buffers can be used to encode graphics, blit, or compute commands to be submitted to the device.

A command buffer can only be used on a single thread. Multi-threaded render, blit, or compute passes must create a new command buffer on each thread.

Returns
A new command buffer.

Implements impeller::Context.

◆ DescribeGpuModel()

std::string flutter::testing::android::TestImpellerContext::DescribeGpuModel ( ) const
inlineoverridevirtual

Implements impeller::Context.

46{ return ""; }

◆ GetBackendType()

impeller::Context::BackendType flutter::testing::android::TestImpellerContext::GetBackendType ( ) const
inlineoverridevirtual

Get the graphics backend of an Impeller context.

        This is useful for cases where a renderer needs to track and
        lookup backend-specific resources, like shaders or uniform
        layout information.

        It's not recommended to use this as a substitute for
        per-backend capability checking. Instead, check for specific
        capabilities via `GetCapabilities()`.
Returns
The graphics backend of the Context.

Implements impeller::Context.

Definition at line 42 of file android_context_gl_unittests.cc.

◆ GetCapabilities()

const std::shared_ptr< const impeller::Capabilities > & flutter::testing::android::TestImpellerContext::GetCapabilities ( ) const
inlineoverridevirtual

Get the capabilities of Impeller context. All optionally supported feature of the platform, client-rendering API, and device can be queried using the Capabilities.

Returns
The capabilities. Can never be nullptr for a valid context.

Implements impeller::Context.

◆ GetCommandQueue()

std::shared_ptr< impeller::CommandQueue > flutter::testing::android::TestImpellerContext::GetCommandQueue ( ) const
inlineoverridevirtual

Return the graphics queue for submitting command buffers.

Implements impeller::Context.

83 }

◆ GetPipelineLibrary()

std::shared_ptr< impeller::PipelineLibrary > flutter::testing::android::TestImpellerContext::GetPipelineLibrary ( ) const
inlineoverridevirtual

Returns the library of pipelines used by render or compute commands.

Returns
The pipeline library. Can never be nullptr for a valid context.

Implements impeller::Context.

◆ GetResourceAllocator()

std::shared_ptr< impeller::Allocator > flutter::testing::android::TestImpellerContext::GetResourceAllocator ( ) const
inlineoverridevirtual

Returns the allocator used to create textures and buffers on the device.

Returns
The resource allocator. Can never be nullptr for a valid context.

Implements impeller::Context.

59 {

◆ GetSamplerLibrary()

std::shared_ptr< impeller::SamplerLibrary > flutter::testing::android::TestImpellerContext::GetSamplerLibrary ( ) const
inlineoverridevirtual

Returns the library of combined image samplers used in shaders.

Returns
The sampler library. Can never be nullptr for a valid context.

Implements impeller::Context.

◆ GetShaderLibrary()

std::shared_ptr< impeller::ShaderLibrary > flutter::testing::android::TestImpellerContext::GetShaderLibrary ( ) const
inlineoverridevirtual

Returns the library of shaders used to specify the programmable stages of a pipeline.

Returns
The shader library. Can never be nullptr for a valid context.

Implements impeller::Context.

Definition at line 63 of file android_context_gl_unittests.cc.

63 {
65 }

◆ IsValid()

bool flutter::testing::android::TestImpellerContext::IsValid ( ) const
inlineoverridevirtual

Determines if a context is valid. If the caller ever receives an invalid context, they must discard it and construct a new context. There is no recovery mechanism to repair a bad context.

It is convention in Impeller to never return an invalid context from a call that returns an pointer to a context. The call implementation performs validity checks itself and return a null context instead of a pointer to an invalid context.

How a context goes invalid is backend specific. It could happen due to device loss, or any other unrecoverable error.

Returns
If the context is valid.

Implements impeller::Context.

Definition at line 48 of file android_context_gl_unittests.cc.

48{ return true; }

◆ Shutdown()

void flutter::testing::android::TestImpellerContext::Shutdown ( )
inlineoverridevirtual

Force all pending asynchronous work to finish. This is achieved by deleting all owned concurrent message loops.

Implements impeller::Context.

Definition at line 85 of file android_context_gl_unittests.cc.

◆ UpdateOffscreenLayerPixelFormat()

bool flutter::testing::android::TestImpellerContext::UpdateOffscreenLayerPixelFormat ( impeller::PixelFormat  format)
inlineoverridevirtual

Reimplemented from impeller::Context.
