static final Clustering.Serializer serializer

STATIC_CLUSTERING

static final Clustering<java.nio.ByteBuffer> STATIC_CLUSTERING

The special cased clustering used by all static rows. It is a special case in the sense that it's always empty, no matter how many clustering columns the table has.

EMPTY

static final Clustering<java.nio.ByteBuffer> EMPTY

Empty clustering for tables having no clustering columns.

Method Detail

unsharedHeapSizeExcludingData

long unsharedHeapSizeExcludingData()

clone

default Clustering<?> clone(ByteBufferCloner cloner)

toString

default java.lang.String toString(TableMetadata metadata)

Description copied from interface: ClusteringPrefix

Generates a proper string representation of the prefix.

Specified by:

toString in interface ClusteringPrefix<V>

Parameters:

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

Returns:

a human-readable string representation fo this prefix.

toCQLString

default java.lang.String toCQLString(TableMetadata metadata)

make
