Package org.apache.cassandra.db

Interface ClusteringBoundary<V>

All Superinterfaces:

Clusterable<V>, ClusteringBoundOrBoundary<V>, ClusteringPrefix<V>, IMeasurableMemory

All Known Implementing Classes:

ArrayClusteringBoundary, BufferClusteringBoundary

public interface ClusteringBoundary<V>
extends ClusteringBoundOrBoundary<V>

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 Details

invert

ClusteringBoundary<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.

openBound

ClusteringBound<V> openBound(boolean reversed)

closeBound

ClusteringBound<V> closeBound(boolean reversed)

create

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

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>
