execute()

virtual void m::MatchBase::execute ( setup_t  setup, pipeline_t  pipeline, teardown_t  teardown  ) const

pure virtualinherited

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.
