| Constructor Summary | |
| public | ReverseComparator()
Creates a comparator that compares objects based on the inverse of their
natural ordering. | | public | ReverseComparator(Comparator comparator)
Creates a comparator that inverts the comparison
of the given comparator. |
| ReverseComparator | | public ReverseComparator()(Code) | | Creates a comparator that compares objects based on the inverse of their
natural ordering. Using this Constructor will create a ReverseComparator
that is functionally identical to the Comparator returned by
java.util.Collections.reverseOrder().
See Also: java.util.Collections.reverseOrder |
| ReverseComparator | | public ReverseComparator(Comparator comparator)(Code) | | Creates a comparator that inverts the comparison
of the given comparator. If you pass in null,
the ReverseComparator defaults to reversing the
natural order, as per
java.util.Collections.reverseOrder .
Parameters:
comparator - Comparator to reverse |
| compare | | public int compare(Object obj1, Object obj2)(Code) | | Compares two objects in reverse order.
Parameters:
obj1 - the first object to compare
Parameters:
obj2 - the second object to compare negative if obj1 is less, positive if greater, zero if equal |
| equals | | public boolean equals(Object object)(Code) | | Returns true iff that Object is
is a
Comparator whose ordering is known to be
equivalent to mine.
This implementation returns true
iff object.
Object.getClass getClass()
equals this.getClass(), and the underlying
comparators are equal.
Subclasses may want to override this behavior to remain consistent
with the
Comparator.equals(Object) equals contract.
Parameters:
object - the object to compare to true if equal

| hashCode | | public int hashCode()(Code) | | Implement a hash code for this comparator that is consistent with
ReverseComparator.equals(Object) equals .
a suitable hash code
since:
