com.h3c.util.persistence.cassandra.entitymgr.column.ColumnCommand<K,E>

com.h3c.util.persistence.cassandra.entitymgr.column.ColumnCommandAdapter<K,E>

Type Parameters:

K - type of the column key or name

E - type of the command result

public class ColumnCommandAdapter<K extends Serializable & Comparable<K>,E>
extends ColumnCommand<K,E>

An abstract adapter class for executing column commands. The methods in this class returns the default value. This class exists as convenience for creating event commands.

Class used to execute a command on a column when just a subset of type of columns is considered by the command; for the rest of column types a default value is returned.

This class is not thread safe.
