Interface FileSmartDirectorySession

All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession
public interface FileSmartDirectorySession extends OsidSession

This session manages queries and sequencing to create "smart" dynamic catalogs. A FileQuery can be retrieved from this session and mapped to this Directory to create a virtual collection of files. The files may be sequenced using the FileSearchOrder from this session.

This Directory has a default query that matches any file and a default search order that specifies no sequencing. The queries may be examined using a FileQueryInspector . The query may be modified by converting the inspector back to a FileQuery .
