Class ColumnName<K extends Serializable & Comparable<K>,V>

java.lang.Object

com.hp.util.type.AbstractValueType<K>

com.hp.util.persistence.cassandra.entitymgr.column.ColumnName<K,V>

Type Parameters:

K - type of the column key or name

V - type of the column value

All Implemented Interfaces:

Serializable, Comparable<ColumnName<K,?>>

public final class ColumnName<K extends Serializable & Comparable<K>,V>
extends AbstractValueType<K>
implements Comparable<ColumnName<K,?>>
