示例1: retainAll
import java.util.SortedSet; //導入方法依賴的package包/類
@Override
public synchronized boolean retainAll(Collection<?> c) {
SortedSet<E> newSet = new TreeSet<E>(internalSet);
boolean changed = newSet.retainAll(c);
internalSet = newSet;
return changed;
}
示例2: doOperation
import java.util.SortedSet; //導入方法依賴的package包/類
/**
* Utility that could be on SortedSet. Allows faster implementation than
* what is in Java for doing addAll, removeAll, retainAll, (complementAll).
* @param a first set
* @param relation the relation filter, using ANY, CONTAINS, etc.
* @param b second set
* @return the new set
