29  * Java Bean {@link java.beans.PropertyEditor} which converts Strings into
30  * {@link InetSocketAddress} objects. Valid values include a hostname or ip
31  * address and a port number separated by a ':'. If the hostname or ip address
32  * is omitted the wildcard address will be used. E.g.:
33  * <code>google.com:80</code>, <code>:22</code>, <code>192.168.0.1:110</code>.
34  * <p>
35  * Use Spring's CustomEditorConfigurer to use this property editor in a Spring
36  * configuration file. See chapter 3.14 of the Spring Reference Documentation
37  * for more info.
