OSID - osid.mapping.path.SignalSearchSession Service Interface Definition

Interface	osid.mapping.path.SignalSearchSession
Implements	`osid.mapping.path.SignalQuerySession`
Used By	`osid.mapping.path.MappingPathManager`
Used By	`osid.mapping.path.MappingPathProxyManager`
Description	This session provides methods for searching among `Signal` objects. The search query is constructed using the `SignalQuery`. `getSignalsByQuery()` is the basic search method and returns a list of `Signals`. A more advanced search may be performed with `getSignalsBySearch()` .It accepts a `SignalSearch` in addition to the query for the purpose of specifying additional options affecting the entire search, such as ordering. `getSignalsBySearch()` returns a `SignalSearchResults` that can be used to access the resulting `SignalList` or be used to perform a search within the result set through `SignalSearch` . This session defines views that offer differing behaviors for searching. federated map view: searches include signals in maps of which this map is an ancestor in the map hierarchy isolated map view: searches are restricted to signals in this map Signals may have a query record indicated by their respective record types. The query record is accessed via the `SignalQuery`.
Method	getSignalSearch
Description	Gets a signal search.
Return	`osid.mapping.path.SignalSearch`		the signal search
Compliance	`mandatory`		This method must be implemented.
Method	getSignalSearchOrder
Description	Gets a signal search order. The `SignalSearchOrder` is supplied to a `SignalSearch` to specify the ordering of results.
