Interface AFReducer

All Known Implementing Classes:

A2FReducer, F2AReducer, FIsAReducer

public interface AFReducer

AFReducer implementations reduce AFConstraints into one or more "simpler" AFConstraints until these constraints are irreducible.

See Also:

There is one AFReducer for each type of AFConstraint.

Method Summary

Modifier and Type	Method and Description
boolean	reduce(AFConstraint constraint, Set<AFConstraint> newConstraints) Determines if the input constraint should be handled by this reducer.

Method Detail

reduce

boolean reduce(AFConstraint constraint,
               Set<AFConstraint> newConstraints)

Determines if the input constraint should be handled by this reducer. If so: Reduces the constraint into one or more new constraints. Any new constraint that can still be reduced is placed in newConstraints. New irreducible constraints are placed in finish. Return true Return false (indicating that some other reducer needs to handle this constraint) If false is returned, the reducer should NOT place any constraints in newConstraints or finished

Parameters:

constraint - the constraint to reduce

newConstraints - the new constraints that may still need to be reduced

Returns:

true if the input constraint was handled by this reducer, false otherwise
