Class WFSNotePollingGraphUpdater

java.lang.Object

org.opentripplanner.updater.PollingGraphUpdater

org.opentripplanner.updater.street_notes.WFSNotePollingGraphUpdater

All Implemented Interfaces:

GraphUpdater, JsonConfigurable

Direct Known Subclasses:

WinkkiPollingGraphUpdater

public abstract class WFSNotePollingGraphUpdater
extends PollingGraphUpdater

A graph updater that reads a WFS-interface and updates a DynamicStreetNotesSource. Useful when reading geodata from legacy/external sources, which are not based on OSM and where data has to be matched to the street network. Classes that extend this class should provide getNote which parses the WFS features into notes. Also the implementing classes should be added to the GraphUpdaterConfigurator

Method Detail

configurePolling

protected void configurePolling(Graph graph,
                                com.fasterxml.jackson.databind.JsonNode config)
                         throws Exception

Here the updater can be configured using the properties in the file 'Graph.properties'. The property frequencySec is already read and used by the abstract base class.

Specified by:

configurePolling in class PollingGraphUpdater

Throws:

Exception

setGraphUpdaterManager

public void setGraphUpdaterManager(GraphUpdaterManager updaterManager)

Here the updater gets to know its parent manager to execute GraphWriterRunnables.

setup

public void setup(Graph graph)
           throws IOException,
                  org.opengis.referencing.FactoryException

Setup the WFS data source and add the DynamicStreetNotesSource to the graph

Throws:

IOException

org.opengis.referencing.FactoryException

teardown

public void teardown()

Description copied from interface: GraphUpdater

Here the updater can clean up after itself.

runPolling

protected void runPolling()
                   throws IOException

The function is run periodically by the update manager. The extending class should provide the getNote method. It is not implemented here as the requirements for different updaters can be vastly different dependent on the data source.

Specified by:

runPolling in class PollingGraphUpdater

Throws:

IOException

getNote

protected abstract Alert getNote(org.opengis.feature.simple.SimpleFeature feature)

Parses a SimpleFeature and returns an Alert if the feature should create one. The alert should be based on the fields specific for the specific WFS feed.
