All Known Implementing Classes:

AbstractScriptSearchProvider, AbstractSearchProvider, ClientScriptSearchProvider, ModuleLibrarySearchProvider, NamedQuerySearchProvider, PipelineSearchProvider, ScriptConfigSearchProvider, ScriptLibrarySearchProvider, ScriptSearchManager, TagSearchProvider, ViewSearchProvider, VisionSearchProvider

public interface SearchProvider

Defines a coarse unit of searchability. SearchProviders can have sub-categories and selectable objects that define the set of what will be searched.

Method Detail

getName

java.lang.String getName()

Returns the name of the search provider, which will be used in the gateway and a UI to uniquely identify the provider. It is expected to be in the current session's language.

getCategories

@Nullable
java.util.List<java.lang.Object> getCategories()

Returns a list of "categories", or sub-selectable units, supported by this search provider. The actual objects will be passed back in to retrieveSearchableObjects when the search is executed.

hasSelectableObjects

boolean hasSelectableObjects()

Whether or not the set of objects searched by this provider is selectable- for examples, which groups or windows are to be searched.

selectedObjectsToString

java.lang.String selectedObjectsToString(java.util.List<java.lang.Object> objects)

Formats the list of selected objects as a brief string.

selectObjects

void selectObjects(SearchProvider.SelectedObjectsHandler handler)

Instructs the SearchProvider to show a dialog in order to select the objects to search. The object are returned through the passed in handler, and will later be passed into executeSearch.

retrieveSearchableObjects

java.util.Iterator<SearchObject> retrieveSearchableObjects(java.util.Collection<java.lang.Object> categories,
                                                           java.util.List<java.lang.Object> searchObjects,
                                                           TaskProgressListener progress)

Returns an iterator that provides all of the objects described by the parameters. The iterator will generally stream the results, calculating the next object on each call to hasNext().

The provided ProgressListener can be used to provide progress information as the Iterator is processed. Some providers may not be able to calculate progress, in which case they should call setIndeterminate(true), but the provider implementors are encouraged to provide anything they can, even if it's very coarse.

Parameters:

categories - indicates the user selection (if applicable) of which categories should be searched.

searchObjects - the user selected objects (if applicable) to be searched.

progress - a progress listener for this provider, which can be updated as the returned Iterator is used. If not supported, the provider should call setIndeterminate(true).

notifySearchClosed

void notifySearchClosed()

Called when the search dialog box is closed, so that the search provider can release any cached resources

getExecutor

default java.util.Optional<SearchExecutor> getExecutor(SearchObjectPredicate predicate)
