invert

public ClusteringBound invert()

Description copied from class: ClusteringBoundOrBoundary

Returns the inverse of the current bound.

This invert both start into end (and vice-versa) and inclusive into exclusive (and vice-versa).

Specified by:

invert in class ClusteringBoundOrBoundary

Returns:

the invert of this bound. For instance, if this bound is an exlusive start, this return an inclusive end with the same values.

copy

public ClusteringBound copy(AbstractAllocator allocator)

Overrides:

copy in class ClusteringBoundOrBoundary

isStart

public boolean isStart()

isEnd

public boolean isEnd()

isInclusive

public boolean isInclusive()

isExclusive

public boolean isExclusive()
