public interface Cacheable
The Cacheable
interface is a tagging interface that
identifies the output of a dynamic content handler as Cacheable.
The methods on a Cacheable
instance are
invoked by the ServingXML framework through reflection.
A Cacheable
implementation services the request with a
method of the form
public long getLastModified(Object key, long timestamp, long elapsed) {where the first parameter is a
ServiceContext
,
the second parameter may be any user defined interface that
follows bean naming conventions for accessors,
and the third parameter is the timestamp when the dynamic content was created,
and the fourth parameter is the amount of time elapsed since then.
