Constructor Details

BufferClusteringBound

public BufferClusteringBound(ClusteringPrefix.Kind kind,
 ByteBuffer[] values)

Method Details

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<ByteBuffer> 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<ByteBuffer>

Specified by:

invert in interface ClusteringBoundOrBoundary<ByteBuffer>

Returns:

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

clone

public ClusteringBound<ByteBuffer> clone(ByteBufferCloner cloner)

Specified by:

clone in interface ClusteringBound<ByteBuffer>

Specified by:

clone in interface ClusteringBoundOrBoundary<ByteBuffer>

create

public static BufferClusteringBound create(ClusteringPrefix.Kind kind,
 ByteBuffer[] values)

inclusiveStartOf

public static BufferClusteringBound inclusiveStartOf(ByteBuffer... values)

inclusiveEndOf

public static BufferClusteringBound inclusiveEndOf(ByteBuffer... values)

exclusiveStartOf

public static BufferClusteringBound exclusiveStartOf(ByteBuffer... values)

exclusiveEndOf

public static BufferClusteringBound exclusiveEndOf(ByteBuffer... values)
