Class ConsensusLdapConnectionLivenessValidator

java.lang.Object

edu.amc.sakai.user.ConsensusLdapConnectionLivenessValidator

All Implemented Interfaces:

LdapConnectionLivenessValidator

public class ConsensusLdapConnectionLivenessValidator
extends Object
implements LdapConnectionLivenessValidator

A "federating" LdapConnectionLivenessValidator implemenation which requires all delegates to validate a given connection. Considers a connection invalid if any one member returns false from LdapConnectionLivenessValidator.isConnectionAlive(com.novell.ldap.LDAPConnection).

Intended for chaining together multiple liveness strategies. E.g., to assist with logging, an institution may choose to require both MaxLifetimeLdapConnectionLivenessValidator and SearchExecutingLdapConnectionLivenessValidator to validate connection liveness.
