This interface compares two sets. It has only one method, which compares the sets, and a number of fields that are used to report the result of the set comparison.

Methods

compareSet

int compareSet (Object other);

Compares this set against another, and returns one of the previous results.

Return Value:

Returns one of the field values of this interface.

Parameter	Description
other	The set to compare this set against.

Fields

DISJOINT

The sets are disjoint.

EMPTY

Both sets are empty sets.

EMPTY_SUBSET

This set is empty, and the other set is not empty.

EMPTY_SUPERSET

This set is not empty, and the other set is empty.

EQUAL

The sets are identical.

OVERLAP

The sets overlap.

SUBSET

This set is a subset of the other set, and is not equal to the other set.

SUPERSET

This set is a superset of the other set, and is not equal to the other set.
