Class ContextIdFactory

java.lang.Object
  org.eclipse.higgins.idas.registry.contextid.ContextIdFactory

public class ContextIdFactory

extends Object

This is a helper class that can be used to obtain an IContextId in the following ways: 1) From a local file (an XRDS document) 2) From a XRI (which yields an XRDS document, using XRI resolution) 3) From a URL (which yields an XRDS document, using Yadis discovery) 4) From a stream (from which an XRDS document is read) 5) From the ContextId list that was passed to IdASRegistry using the Configuration API. 6) From a string, in which case the following will be tried in order: 1), 2), 3), 5) In any case, the ContextId contains everything needed to instantiate a context. This is: - One or more context types (used by IdASRegistry to find a suitable context factory). - Context configuration. - In the case of XRDS, optional URI(s) of the service endpoint that was used for the ContextId.
