setLocalMapCache

public void setLocalMapCache(File cacheDir)

Sets the local tiles cache from a directory

Parameters:

cacheDir - Where the cache is located

createSearchPanelQueryBehavior

public SearchBarListener createSearchPanelQueryBehavior()

Creates a SearchBarListener that handles search queries for the search panel. It uses caching to store previously fetched results for stops and routes to improve performance on repeated searches. When a search is performed, it checks the cache first before querying the database. The results are then rendered in the search panel of the main frame.

Returns:

a SearchBarListener for handling search queries in the search panel

• SearchBarListener
• StopModel
• RouteDirection
• DatabaseService

createPreferPanelQueryBehavior

public SearchBarListener createPreferPanelQueryBehavior()

Creates a SearchBarListener that handles search queries for the prefer panel. It fetches favorite stops and routes for the logged-in user based on the search text. The results are then displayed in the prefer panel of the main frame. This listener does not use caching since favorite items are user-specific and may change frequently.

Returns:

a SearchBarListener for handling search queries in the prefer panel

• RouteDirection
