Member Function Documentation

finalize()

GrProcessorSet::Analysis skgpu::ganesh::PathTessellateOp::finalize ( const GrCaps &  , const GrAppliedClip *  , GrClampType    )

overrideprivatevirtual

This is called after the GrAppliedClip has been computed and just prior to recording the op or combining it with a previously recorded op. The op should convert any proxies or resources it owns to "pending io" status so that resource allocation can be more optimal. Additionally, at this time the op must report whether a copy of the destination (or destination texture itself) needs to be provided to the GrXferProcessor when this op executes.

Implements GrDrawOp.
