Interface Lookup

All Superinterfaces:

Disposable

public interface Lookup
extends Disposable

Constructs an XML source document that represents an individual ATOM entry. This entry contains metadata for the POC in addition to the URLs to the POC services that are associated with the URI.

Implementations of Lookup do not need to be threadsafe, because clients will call the LookupService to get new instances on a per-context basis. Cleanup and potential object pooling can be done via the implementation of the Disposable interface. Clients are required to call Disposable.dispose() for each instance of Lookup.

Example of a calling sequence

 LookupService service = ...;
 Lookup lookup = service.newLookup(...);
 try {
   Source src = lookup.getSource();
   ...
 } finally {
   lookup.dispose();
 }
 

Since:

6.1.0

Note:

This interface is designed to be implemented by clients.
