Method Details

queryCollection

public Promise<QueryResponse,ResourceException> queryCollection(org.forgerock.services.context.Context context,
 QueryRequest request,

Description copied from interface: CollectionResourceProvider

Searches the collection for all resources which match the query request criteria.

Implementations must invoke QueryResourceHandler.handleResource(ResourceResponse) for each resource which matches the query criteria. Once all matching resources have been returned implementations are required to return either a QueryResponse if the query has completed successfully, or ResourceException if the query did not complete successfully (even if some matching resources were returned).

Specified by:

queryCollection in interface CollectionResourceProvider

Parameters:

context - The request server context.

request - The query request.

handler - The query resource handler to be notified for each matching resource.

Returns:

A Promise containing the result of the operation.

readInstance

public Promise<ResourceResponse,ResourceException> readInstance(org.forgerock.services.context.Context context,

Reads an existing resource within the collection.

Specified by:

Parameters:

Returns:

A Promise containing the result of the operation.
