encode

public void encode(ServiceEncoding encoding)

Description copied from interface: ServiceEncoder

Invoked by the LinkFactory to encode the request. Encoding is the process of modifying the encoding object to represent the same data in a different format; the canoncial example is to replace the ServiceConstants.PAGEand ServiceConstants.SERVICEquery parameters with a servlet path (i.e., "/Home.html", if the ".html" extension is mapped to the page service).

The LinkFactory iterates over a collection of encoders, stopping once the ServiceRequestEncoding is modified in any way.
