Constructor Detail

ArrayClusteringBound

public ArrayClusteringBound(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.

invert

public ClusteringBound<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 ClusteringBound<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.

copy

public ClusteringBound<java.nio.ByteBuffer> copy(AbstractAllocator allocator)

Specified by:

copy in interface ClusteringBound<byte[]>

Specified by:

copy in interface ClusteringBoundOrBoundary<byte[]>

create

public static ArrayClusteringBound create(ClusteringPrefix.Kind kind,
                                          byte[][] values)
