Method Detail

eval

public <T> boolean eval(java.util.Map<java.lang.String,T> variableBindings)
             throws UnboundVariableException

Description copied from interface: Predicate

Evaluates the predicate with the given map of pairs.

Parameters:

variableBindings - - a map that specifies the bindings for the predicate variables.

Returns:

true, if the predicate is true; false, otherwise.

Throws:

UnboundVariableException - - if some variable necessary to evaluate the predicate was not bound.

equals

public boolean equals(Predicate p,
                      boolean deep)

Description copied from interface: Predicate

Compares this predicate to the given predicate p.

deep - true if type, variable names, and values have to match,
false if only type has to match.

Returns:

copy

public Predicate copy()

Description copied from interface: Predicate

makes an exact copy of this predicate

Returns:
