Constructor Summary

ChainRestrictor()
Instantiates an empty ChainRestrictor.

Method Summary

void	add(Restrictor restrictor) Adds the given Restrictor to the chain so that it will be applied.
void	add(Restrictor restrictor, boolean is_comparator) Adds the given Restrictor to the chain and uses it for the sort order.
void	clear() Clears list of restictors in chain so that no restrictors will be applied.
int	compare(Object obj1, Object obj2) Compares objects for sort order.
boolean	keep(Object o) Indicates if the given Object should be kept based on the Restrictors in the chain.
void	remove(Restrictor restrictor) Removes the given Restrictor from the chain so it will not be applied.
void	setComparator(Comparator comp) Sets the Comparator to be used for the sort order.
