◆ onAbandon()

void GrGLAttachment::onAbandon ( )

Overridden to abandon any internal handles, ptrs, etc to backend API resources. This may be called when the underlying 3D context is no longer valid and so no backend API calls should be made.

Reimplemented from GrGpuResource.

Definition at line 132 of file GrGLAttachment.cpp.

◆ onRelease()

void GrGLAttachment::onRelease ( )

overrideprotectedvirtual

Overridden to free GPU resources in the backend API.

Reimplemented from GrGpuResource.

◆ setMemoryBacking()

void GrGLAttachment::setMemoryBacking	(	SkTraceMemoryDump *	,
		const SkString &
	)		const

overrideprotectedvirtual

Allows subclasses to add additional backing information to the SkTraceMemoryDump.

Reimplemented from GrGpuResource.
