Interface Connection

All Superinterfaces:
AutoCloseable, Closeable
All Known Implementing Classes:
AbstractAsynchronousConnection, AbstractConnection, AbstractConnectionWrapper, AbstractSynchronousConnection
public interface Connection extends Closeable
A connection with a Directory Server over which read and update operations may be performed. See RFC 4511 for the LDAPv3 protocol specification and more information about the types of operations defined in LDAP.

Operation processing

Operations may be performed synchronously or asynchronously depending on the method chosen. Asynchronous methods can be identified by their Async suffix.

Performing operations synchronously

Synchronous methods block until a response is received from the Directory Server, at which point an appropriate Result object is returned if the operation succeeded, or thrown as an LdapException if the operation failed.

Since synchronous operations block the calling thread, the only way to abandon a long running operation is to interrupt the calling thread from another thread. This will cause the calling thread unblock and throw a CancelledResultException whose cause is the underlying InterruptedException.

Performing operations asynchronously

Asynchronous methods, identified by their Async suffix, are non-blocking, returning a LdapPromise or sub-type thereof which can be used for retrieving the result using the Promise.get() method. Operation failures, for whatever reason, are signaled by the Promise.get() method throwing an LdapException.

In addition to returning a LdapPromise, all asynchronous methods accept a LdapResultHandler which will be notified upon completion of the operation.

Synchronous operations are easily simulated by immediately getting the result: 

 Connection connection = ...;
 AddRequest request = ...;
 // Will block until operation completes, and
 // throws exception on failure.
 connection.add(request).get();
Operations can be performed in parallel while taking advantage of the simplicity of a synchronous application design: 
 Connection connection1 = ...;
 Connection connection2 = ...;
 AddRequest request = ...;
 // Add the entry to the first server (don't block).
 LdapPromise promise1 = connection1.add(request);
 // Add the entry to the second server (in parallel).
 LdapPromise promise2 = connection2.add(request);
 // Total time = is O(1) instead of O(n).
 promise1.get();
 promise2.get();
More complex client applications can take advantage of a fully asynchronous event driven design using LdapResultHandlers: 
 Connection connection = ...;
 SearchRequest request = ...;
 // Process results in the search result handler
 // in a separate thread.
 SearchResponseHandler handle = ...;
 connection.search(request, handler);

Closing connections

Applications must ensure that a connection is closed by calling close() even if a fatal error occurs on the connection. Once a connection has been closed by the client application, any attempts to continue to use the connection will result in an IllegalStateException being thrown. Note that, if a fatal error is encountered on the connection, then the application can continue to use the connection. In this case all requests subsequent to the failure will fail with an appropriate LdapException when their result is retrieved.

Event notification

Applications can choose to be notified when a connection is closed by the application, receives an unsolicited notification, or experiences a fatal error by registering a ConnectionEventListener with the connection using the addConnectionEventListener(org.forgerock.opendj.ldap.ConnectionEventListener) method.

  • Method Details

    • abandonAsync

      LdapPromise<Void> abandonAsync(AbandonRequest request)
      Abandons the unfinished operation identified in the provided abandon request.

      Abandon requests do not have a response, so invoking the method get() on the returned promise will not block, nor return anything (it is Void), but may throw an exception if a problem occurred while sending the abandon request. In addition the returned promise may be used in order to determine the message ID of the abandon request.

      Note: a more convenient approach to abandoning unfinished asynchronous operations is provided via the Promise.cancel(boolean) method.

      Parameters:
      request - The request identifying the operation to be abandoned.
      Returns:
      A promise whose result is Void.
      Throws:
      UnsupportedOperationException - If this connection does not support abandon operations.
      IllegalStateException - If this connection has already been closed, i.e. if isClosed() == true.
      NullPointerException - If request was null.

    • close

      void close()

      This method is equivalent to the following code: 

       UnbindRequest request = new UnbindRequest();
 connection.close(request);
      Calling close on a connection that is already closed has no effect.
