Member Function Documentation

Predicate & RS::Predicate::operator= (  const Predicate &    obj )

Assignment operator. Assigns obj to this object. Definition at line 72 of file Predicate.cc. References lastUpdateNumber, and viewManager.

FuzzyBool RS::Predicate::operator() (    )  [inline, virtual]

Function application operator. Will call evalute(). Reimplemented in RS::AmIClosestToBall, RS::AmIFirstToBall, RS::IsBallKnown, RS::IsCatchAllowed, and RS::PassKick. Definition at line 60 of file Predicate.icc. References evaluate().
