All Implemented Interfaces:

org.apache.cocoon.acting.Action, Serviceable, ThreadSafe

public class ResourceExistsAction

extends org.apache.cocoon.acting.ServiceableAction

implements ThreadSafe

This action simply checks to see if a resource identified by the src sitemap attribute exists or not. The action returns empty Map if resource exists, null otherwise.

Instead of src attribute, source can be specified using parameter named url (this is old syntax, should be removed soon).

NOTE: ResourceExistsSelector should be preferred to this component, as the semantics of a Selector better matches the supplied functionality.
