inlineoverridevirtual

Executes this physical operator match.

Recursively calls children operators to execute. The three callbacks are specified by the parent operator and are used as follows: setup for some initializations, pipeline for the actual computation, and teardown for post-processing.

Implements m::MatchBase.
