Interface HierarchySearchSession

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, HierarchyQuerySession, OsidSession

public interface HierarchySearchSession
extends HierarchyQuerySession

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

getHierarchiesByQuery() is the basic search method and returns a list of Hierarchy objects. A more advanced search may be performed with getHierarchiesBySearch(). It accepts a HierarchySearch in addition to the query for the purpose of specifying additional options affecting the entire search, such as ordering. getHierarchiesBySearch() returns a HierarchySearchResults that can be used to access the resulting HierarchyList or be used to perform a search within the result set through HierarchySearch.

Hierarchies may have a query record indicated by their respective record types. The query record query is accessed via the HierarchuQuery.
