DirectorySearchSession

public interface DirectoryQuerySession
extends OsidSession

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

This session defines views that offer differing behaviors for searching.

• federated directory view: searches include directories in directories of which this directory is an ancestor
• isolated directory view: searches are restricted to diectories in this directory only
