public class ClusteringBoundary
extends ClusteringBoundOrBoundary

The threshold between two different ranges, i.e. a shortcut for the combination of two ClusteringBounds -- one specifying the end of one of the ranges, and its (implicit) complement specifying the beginning of the other.

Method Detail

create

public static ClusteringBoundary create(ClusteringPrefix.Kind kind,
                                        java.nio.ByteBuffer[] values)

invert

public ClusteringBoundary 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 ClusteringBoundary copy(AbstractAllocator allocator)

Overrides:

copy in class ClusteringBoundOrBoundary

openBound

public ClusteringBound openBound(boolean reversed)

closeBound

public ClusteringBound closeBound(boolean reversed)
