public interface RequestTransactionQuerySession extends OsidSession

This session provides methods for searching among RequestTransaction objects. The search query is constructed using the RequestTransactionQuery .

This session defines views that offer differing behaviors for searching.

  • federated distributor view: searches include request transactions in distributors of which this distributor is an ancestor in the distributor hierarchy
  • isolated distributor view: searches are restricted to request transactions in this distributor

Request transactions may have a query record indicated by their respective record types. The query record is accessed via the RequestTransactionQuery .
