Field Details

BOTTOM

static final ClusteringBound<?> BOTTOM

The smallest start bound, i.e. the one that starts before any row.

TOP

static final ClusteringBound<?> TOP

The biggest end bound, i.e. the one that ends after any row.

MAX_START

static final ClusteringBound<?> MAX_START

The biggest start bound, i.e. the one that starts after any row.

MIN_END

static final ClusteringBound<?> MIN_END

The smallest end bound, i.e. the one that end before any row.

Method Details

boundKind

static ClusteringPrefix.Kind boundKind(boolean isStart,
 boolean isInclusive)

invert

ClusteringBound<V> 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 ClusteringBoundOrBoundary<V>

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

ClusteringBound<ByteBuffer> clone(ByteBufferCloner cloner)

Specified by:

clone in interface ClusteringBoundOrBoundary<V>

isStart

default boolean isStart()

isEnd

default boolean isEnd()

isInclusive

default boolean isInclusive()

isExclusive

default boolean isExclusive()

isArtificial

default boolean isArtificial()

artificialLowerBound

default ClusteringBound<V> artificialLowerBound(boolean isReversed)

create

static <V> ClusteringBound<V> create(ClusteringPrefix.Kind kind,
 ClusteringPrefix<V> from)

inclusiveStartOf

static <V> ClusteringBound<V> inclusiveStartOf(ClusteringPrefix<V> from)

inclusiveEndOf

static <V> ClusteringBound<V> inclusiveEndOf(ClusteringPrefix<V> from)

exclusiveStartOf

static <V> ClusteringBound<V> exclusiveStartOf(ClusteringPrefix<V> from)

exclusiveEndOf

static <V> ClusteringBound<V> exclusiveEndOf(ClusteringPrefix<V> from)

create

static ClusteringBound<?> create(ClusteringComparator comparator,
 boolean isStart,
 boolean isInclusive,
 Object... values)

asStartBound

default ClusteringBound<V> asStartBound()

Description copied from interface: ClusteringPrefix

Returns this prefix as a start bound. If this prefix is a bound, just returns it asserting that it is a start bound. If this prefix is a clustering, returns an included start bound. If this prefix is a boundary, returns an open bound of it

Specified by:

asStartBound in interface ClusteringPrefix<V>

asEndBound

default ClusteringBound<V> asEndBound()

Description copied from interface: ClusteringPrefix

Returns this prefix as an end bound. If this prefix is a bound, just returns it asserting that it is an end bound. If this prefix is a clustering, returns an included end bound. In this prefix is a boundary, returns a close bound of it.

Specified by:

asEndBound in interface ClusteringPrefix<V>
