Class RootCollection

java.lang.Object
  org.apache.jackrabbit.webdav.jcr.RootCollection

All Implemented Interfaces:

DavResource, SearchResource, TransactionResource, DeltaVResource

public class RootCollection
extends Object

RootCollection represent the WebDAV root resource that does not represent any repository item. A call to getMembers() returns a DavResourceIterator containing only workspace resources resources, thus revealing the names of the accessable JCR workspaces.
