◆ onAbandon()

void GrVkRenderTarget::onAbandon ( )

overrideprotectedvirtual

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 This may be called when the underlying 3D context is no longer valid and so no backend API calls should be made.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 GrRenderTarget.

Reimplemented in GrVkTextureRenderTarget.
