Interface DisconnectHandler

@Extensible
@ThreadSafety(level=INTERFACE_THREADSAFE)
public interface DisconnectHandler

This interface defines an API that may be implemented by a class that should be notified whenever an LDAP connection is closed for any reason. (whether the connection was closed at the request of the client via a method like LDAPConnection.close(), terminated by the server, or closed due to an internal error). This interface may be used by applications to attempt to automatically re-establish connections as soon as they are terminated, potentially falling over to another server.

It is acceptable to attempt to re-connect the connection that has been disconnected, but in general that should only be attempted if DisconnectType.isExpected(DisconnectType) returns true for the provided disconnectType value. The disconnect handler will be temporarily de-registered from the connection so that closing the connection in the course of processing the handleDisconnect(com.unboundid.ldap.sdk.LDAPConnection, java.lang.String, int, com.unboundid.ldap.sdk.DisconnectType, java.lang.String, java.lang.Throwable) method will not cause it to be recursively re-invoked.

Implementations of this interface should be threadsafe to ensure that multiple connections will be able to safely use the same DisconnectHandler instance.
