/**
 * This class provides an implementation of a post-connect processor that can
 * be used to perform StartTLS negotiation on an LDAP connection that is
 * intended to be used in a connection pool.
 * 


 * 
Example
 * The following example demonstrates the use of the StartTLS post-connect
 * processor to create an LDAP connection pool whose connections are secured
 * using StartTLS.  See the Javadoc documentation for the
 * {@link com.unboundid.util.ssl.SSLUtil} class for a more complete explanation
 * of the process for establishin secure connections.
 * 
 * // Configure an SSLUtil instance and use it to obtain an SSLContext.
 * SSLUtil sslUtil = new SSLUtil(new TrustStoreTrustManager(trustStorePath));
 * SSLContext sslContext = sslUtil.createSSLContext();
 *
 * // Establish an insecure connection to the directory server.
 * LDAPConnectionOptions connectionOptions = new LDAPConnectionOptions();
 * connectionOptions.setSSLSocketVerifier(
 *      new HostNameSSLSocketVerifier(true));
 * LDAPConnection connection =
 *      new LDAPConnection(connectionOptions, serverAddress, nonSSLPort);
 *
 * // Use the StartTLS extended operation to secure the connection.
 * ExtendedResult startTLSResult = connection.processExtendedOperation(
 *      new StartTLSExtendedRequest(sslContext));
 *
 * // Create a connection pool that will secure its connections with StartTLS.
 * BindResult bindResult = connection.bind(
 *      "uid=john.doe,ou=People,dc=example,dc=com", "password");
 * StartTLSPostConnectProcessor startTLSProcessor =
 *      new StartTLSPostConnectProcessor(sslContext);
 * LDAPConnectionPool pool =
 *      new LDAPConnectionPool(connection, 1, 10, startTLSProcessor);
 *
 * // Verify that we can use the pool to communicate with the directory server.
 * RootDSE rootDSE = pool.getRootDSE();
 *
 * // Close the connection pool.
 * pool.close();
 *
