Methods

addFeature(feature)

src/ol/source/vectorsource.js, line 126

Add a single feature to the source. If you want to add a batch of features at once, call source.addFeatures() instead.

Name	Type	Description
feature	ol.Feature	Feature to add.

addFeatures(features)

src/ol/source/vectorsource.js, line 195

Add a batch of features to the source.

Name	Type	Description
features	Array.<ol.Feature>	Features to add.

bindTo(key, target, opt_targetKey){ol.ObjectAccessor} inherited experimental

src/ol/object.js, line 326

The bindTo method allows you to set up a two-way binding between a source and target object. The method returns an object with a transform method that you can use to provide from and to functions to transform values on the way from the source to the target and on the way back.

For example, if you had two map views (sourceView and targetView) and you wanted the target view to have double the resolution of the source view, you could transform the resolution on the way to and from the target with the following:

sourceView.bindTo('resolution', targetView)
  .transform(
    function(sourceResolution) {
      // from sourceView.resolution to targetView.resolution
      return 2 * sourceResolution;
    },
    function(targetResolution) {
      // from targetView.resolution to sourceView.resolution
      return targetResolution / 2;
    }
  );

Name	Type	Description
key	string	Key name.
target	ol.Object	Target.
targetKey	string	Target key.

changed() inherited experimental

src/ol/observable.js, line 52

Increases the revision counter and disptches a 'change' event.

Fires:

• change experimental

clear(opt_fast)

src/ol/source/vectorsource.js, line 241

Remove all features from the source.

Name	Type	Description
fast	boolean	Skip dispatching of removefeature events.

forEachFeature(callback, opt_this){S|undefined}

src/ol/source/vectorsource.js, line 280

Iterate through all features on the source, calling the provided callback with each one. If the callback returns any "truthy" value, iteration will stop and the function will return the same value.

Name	Type	Description
callback	function	Called with each feature on the source. Return a truthy value to stop iteration.
this	T	The object to use as this in the callback.

Returns:

The return value from the last call to the callback.

forEachFeatureInExtent(extent, callback, opt_this){S|undefined} experimental

src/ol/source/vectorsource.js, line 331

Iterate through all features whose bounding box intersects the provided extent (note that the feature's geometry may not intersect the extent), calling the callback with each feature. If the callback returns a "truthy" value, iteration will stop and the function will return the same value.

If you are interested in features whose geometry intersects an extent, call the source.forEachFeatureIntersectingExtent() method instead.

Name	Type	Description
extent	ol.Extent	Extent.
callback	function	Called with each feature whose bounding box intersects the provided extent.
this	T	The object to use as this in the callback.

Returns:

The return value from the last call to the callback.

forEachFeatureIntersectingExtent(extent, callback, opt_this){S|undefined} experimental

src/ol/source/vectorsource.js, line 368

Iterate through all features whose geometry intersects the provided extent, calling the callback with each feature. If the callback returns a "truthy" value, iteration will stop and the function will return the same value.

If you only want to test for bounding box intersection, call the source.forEachFeatureInExtent() method instead.

Name	Type	Description
extent	ol.Extent	Extent.
callback	function	Called with each feature whose geometry intersects the provided extent.
this	T	The object to use as this in the callback.

Returns:

The return value from the last call to the callback.

get(key){*} inherited experimental

src/ol/object.js, line 354

Gets a value.

Name	Type	Description
key	string	Key name.

Returns:

Value.

getAttributions(){Array.<ol.Attribution>} inherited

src/ol/source/source.js, line 96

Returns:

Get the closest feature to the provided coordinate.

Name	Type	Description
coordinate	ol.Coordinate	Coordinate.

Returns:

Closest feature.

getExtent(){ol.Extent}

src/ol/source/vectorsource.js, line 481

Get the extent of the features currently in the source.

Returns:

Extent.

getFeatureById(id){ol.Feature}

src/ol/source/vectorsource.js, line 495

Get a feature by its identifier (the value returned by feature.getId()). Note that the index treats string and numeric identifiers as the same. So source.getFeatureById(2) will return a feature with id '2' or 2.

Name	Type	Description
id	string | number	Feature identifier.

Returns:

The feature (or null if not found).

getFeatures(){Array.<ol.Feature>}

Removes all bindings.

unByKey(key) inherited
