/**
 * This class defines a Directory Server task that can be used to populate the
 * values of a composed attribute in existing entries without the need to export
 * the data to LDIF and re-import it.
 * 

 * 

 *   NOTE:  This class, and other classes within the
 *   {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
 *   supported for use against Ping Identity, UnboundID, and
 *   Nokia/Alcatel-Lucent 8661 server products.  These classes provide support
 *   for proprietary functionality or for external specifications that are not
 *   considered stable or mature enough to be guaranteed to work in an
 *   interoperable way with other types of LDAP servers.
 * 

 * 

 * The properties that are available for use with this type of task include:
 * 
    
 *   
  • The names or DNs of the configuration entries for the composed
 *       attribute plugin instances for which to generate values.
    • 
 *   
  • The backend IDs of the backends in which the values are to be
 *       composed.
    • 
 *   
  • The maximum number of entries to update per second.
