Examples of org.apache.wicket.IRequestTarget

org.apache.wicket.IRequestTarget

A request target is the base entity that is the subject of a request. Different types of request have different request targets. For instance a request for a bookmarkable page differs from a request for a link on a previously rendered page, which in turn differs from a request for a shared resource.

It is very important (for mounting) that implementations implement {@link java.lang.Object#equals(java.lang.Object)} and {@link java.lang.Object#hashCode()} in aconsistent way.
Typically, implementations of IRequestTarget are not meant to be used more than once. @author Eelco Hillenius
