Field Detail

serializer

public static final Slice.Bound.Serializer serializer

BOTTOM

public static final Slice.Bound BOTTOM

The smallest and biggest bound. Note that as range tomstone bounds are (special case) of slice bounds, we want the BOTTOM and TOP to be the same object, but we alias them here because it's cleaner when dealing with slices to refer to Slice.Bound.BOTTOM and Slice.Bound.TOP.

TOP

public static final Slice.Bound TOP

withNewKind

public Slice.Bound withNewKind(ClusteringPrefix.Kind kind)

isStart

public boolean isStart()

isEnd

public boolean isEnd()

isInclusive

public boolean isInclusive()

isExclusive

public boolean isExclusive()

invert

public Slice.Bound invert()

Returns the inverse of the current bound.

This invert both start into end (and vice-versa) and inclusive into exclusive (and vice-versa).

Returns:

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

toString

public java.lang.String toString(CFMetaData metadata)

Description copied from interface: ClusteringPrefix

Generates a proper string representation of the prefix.

Parameters:

metadata - the metadata for the table the clustering prefix is of.

Returns:

a human-readable string representation fo this prefix.

toString

public java.lang.String toString(ClusteringComparator comparator)
