Constructor Detail

ArrayClusteringBoundary

public ArrayClusteringBoundary(ClusteringPrefix.Kind kind,
                               byte[][] values)

Method Detail

unsharedHeapSize

public long unsharedHeapSize()

Specified by:

unsharedHeapSize in interface IMeasurableMemory

Returns:

the amount of on-heap memory retained by the object that might be reclaimed if the object were reclaimed, i.e. it should try to exclude globally cached data where possible, or counting portions of arrays that are referenced by the object but used by other objects only (e.g. slabbed byte-buffers), etc.

create

public static ClusteringBoundary<byte[]> create(ClusteringPrefix.Kind kind,
                                                byte[][] values)

invert

public ClusteringBoundary<byte[]> invert()

Description copied from interface: 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 interface ClusteringBoundary<byte[]>

Specified by:

invert in interface ClusteringBoundOrBoundary<byte[]>

Returns:

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

openBound

public ClusteringBound<byte[]> openBound(boolean reversed)

Specified by:

openBound in interface ClusteringBoundary<byte[]>

closeBound

public ClusteringBound<byte[]> closeBound(boolean reversed)

Specified by:

closeBound in interface ClusteringBoundary<byte[]>
