036/**
037 * This class provides an implementation of a post-connect processor that can
038 * be used to perform StartTLS negotiation on an LDAP connection that is
039 * intended to be used in a connection pool.
040 * <BR><BR>
041 * <H2>Example</H2>
042 * The following example demonstrates the use of the StartTLS post-connect
043 * processor to create an LDAP connection pool whose connections are secured
044 * using StartTLS:
045 * <PRE>
046 * // Configure an SSLUtil instance and use it to obtain an SSLContext.
047 * SSLUtil sslUtil = new SSLUtil(new TrustStoreTrustManager(trustStorePath));
048 * SSLContext sslContext = sslUtil.createSSLContext();
049 *
050 * // Establish an insecure connection to the directory server.
051 * LDAPConnection connection = new LDAPConnection(serverAddress, nonSSLPort);
052 *
053 * // Use the StartTLS extended operation to secure the connection.
054 * ExtendedResult startTLSResult = connection.processExtendedOperation(
055 *      new StartTLSExtendedRequest(sslContext));
056 *
057 * // Create a connection pool that will secure its connections with StartTLS.
058 * BindResult bindResult = connection.bind(
059 *      "uid=john.doe,ou=People,dc=example,dc=com", "password");
060 * StartTLSPostConnectProcessor startTLSProcessor =
061 *      new StartTLSPostConnectProcessor(sslContext);
062 * LDAPConnectionPool pool =
063 *      new LDAPConnectionPool(connection, 1, 10, startTLSProcessor);
064 *
065 * // Verify that we can use the pool to communicate with the directory server.
066 * RootDSE rootDSE = pool.getRootDSE();
067 *
068 * // Close the connection pool.
069 * pool.close();
070 * </PRE>
