MakeGL() [4/4]

sk_sp< GrDirectContext > GrDirectContexts::MakeGL	(	sk_sp< const GrGLInterface >	glInterface,

MakeMetal() [2/2]

sk_sp< GrDirectContext > GrDirectContexts::MakeMetal	(	const GrMtlBackendContext &	backendContext,
		const GrContextOptions &	options
	)

Makes a GrDirectContext which uses Metal as the backend. The GrMtlBackendContext contains a MTLDevice and MTLCommandQueue which should be used by the backend. These objects must have their own ref which will be released when the GrMtlBackendContext is destroyed. Ganesh will take its own ref on the objects which will be released when the GrDirectContext is destroyed.

MakeVulkan() [1/2]

}

MakeVulkan() [2/2]

sk_sp< GrDirectContext > GrDirectContexts::MakeVulkan	(	const GrVkBackendContext &	backendContext,
		const GrContextOptions &	options
	)

The Vulkan context (VkQueue, VkDevice, VkInstance) must be kept alive until the returned GrDirectContext is destroyed. This also means that any objects created with this GrDirectContext (e.g. SkSurfaces, SkImages, etc.) must also be released as they may hold refs on the GrDirectContext. Once all these objects and the GrDirectContext are released, then it is safe to delete the vulkan objects.
