Interface PathSearchSession

All Superinterfaces:

AutoCloseable, Closeable, OsidSession, OsidSession, PathQuerySession

public interface PathSearchSession
extends PathQuerySession

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

getPathsByQuery() is the basic search method and returns a list of Paths. A more advanced search may be performed with getPathsBySearch(). It accepts a PathSearch in addition to the query for the purpose of specifying additional options affecting the entire search, such as ordering. getPathsBySearch() returns a PathSearchResults that can be used to access the resulting PathList or be used to perform a search within the result set through PathSearch.

This session defines views that offer differing behaviors for searching.

• federated graph view: searches include paths in graphs of which this graph is an ancestor in the graph hierarchy
• isolated graph view: searches are restricted to paths in this graph

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

Method Details

getPathSearch

PathSearch getPathSearch()

Gets a path search.

Returns:

the path search

Compliance:

mandatory - This method must be implemented.

getPathSearchOrder

PathSearchOrder getPathSearchOrder()

Gets a path search order. The PathSearchOrder is supplied to a PathSearch to specify the ordering of results.

Parameters:

pathQuery - the path query

pathSearch - the path search

Returns:

the path search results

Throws:

NullArgumentException - pathQuery or pathSearch is null
