Interface QueryResourceHandler

All Known Implementing Classes:

IdentifierQueryResourceHandler

public interface QueryResourceHandler

A completion handler for consuming the results of a query request.

A query result completion handler may be specified when performing query requests using a Connection object. The QueryResourceHandler.handleResource(org.forgerock.json.resource.ResourceResponse) method is invoked for each resource which matches the query criteria, followed by returning a QueryResponse or a ResourceException indicating that no more JSON resources will be returned.

Implementations of these methods should complete in a timely manner so as to avoid keeping the invoking thread from dispatching to other completion handlers.

Synchronization note: each invocation of handleResource for a resource happens-before the invocation of handleResource for the next resource. Invocation of handleResource for the final resource happens-before returning a QueryResponse or a ResourceException are invoked with the final query status. In other words, query resource handler method invocations will occur sequentially and one at a time.

Method Summary

Modifier and Type	Method and Description
boolean	handleResource(ResourceResponse resource) Invoked each time a matching JSON resource is returned from a query request.

Method Detail

handleResource

boolean handleResource(ResourceResponse resource)

Invoked each time a matching JSON resource is returned from a query request. More specifically, if a query request matches 10 resources, then this method will be invoked 10 times, once for each matching resource.

Refer to RequestHandler.handleQuery(org.forgerock.services.context.Context, QueryRequest, QueryResourceHandler) for information regarding the concurrency and the order in which events are processed.

Parameters:

resource - The matching JSON resource.

Returns:

true if this handler should continue to be notified of any remaining matching JSON resources, or false if the remaining JSON resources should be skipped for some reason (e.g. a client side size limit has been reached).
