Methods

addFeature(feature)

src/ol/source/vector.js, line 162

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/vector.js, line 244

Add a batch of features to the source.

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

changed() inherited experimental

src/ol/observable.js, line 58

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

clear(opt_fast)

src/ol/source/vector.js, line 344

Remove all features from the source.

Name	Type	Description
fast	boolean	Skip dispatching of removefeature events.

dispatchEvent(event) inherited experimental

src/ol/observable.js, line 75

Dispatches an event and calls all listeners listening for events of this type. The event parameter can either be a string or an Object with a type property.

Name	Type	Description
event	Object | ol.events.Event | string	Event object.

forEachFeature(callback, opt_this){S|undefined}

src/ol/source/vector.js, line 397

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/vector.js, line 454

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.

When useSpatialIndex is set to false, this method will loop through all features, equivalent to ol.source.Vector#forEachFeature.

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/vector.js, line 480

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

src/ol/object.js, line 148

Gets a value.

Name	Type	Description
key	string	Key name.

Returns:

Value.

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

Returns:

Attributions.

getClosestFeatureToCoordinate(coordinate, opt_filter){ol.Feature}

src/ol/source/vector.js, line 578

Get the closest feature to the provided coordinate.

This method is not available when the source is configured with useSpatialIndex set to false.

Name	Type	Description
coordinate	ol.Coordinate	Coordinate.
filter	function	Feature filter function. The filter function will receive one argument, the feature and it should return a boolean value. By default, no filtering is made.

Returns:

Closest feature.

Get the extent of the features currently in the source.

This method is not available when the source is configured with useSpatialIndex set to false.

Returns:

Extent.

getFeatureById(id){ol.Feature}

src/ol/source/vector.js, line 650

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>}

src/ol/source/vector.js, line 518

coordinate	ol.Coordinate	Coordinate.

Returns:

Features.

getFeaturesCollection(){ol.Collection.<ol.Feature>} experimental

src/ol/source/vector.js, line 508

Get the features collection associated with this source. Will be null unless the source was configured with useSpatialIndex set to false, or with an ol.Collection as features.

Returns:

The collection of features.

getFeaturesInExtent(extent){Array.<ol.Feature>} experimental

src/ol/source/vector.js, line 559

Get all features in the provided extent. Note that this returns an array of all features intersecting the given extent in random order (so it may include features whose geometries do not intersect the extent).

This method is not available when the source is configured with useSpatialIndex set to false.

Name	Type	Description
extent	ol.Extent	Extent.

Returns:

Features.

getFormat(){ol.format.Feature|undefined} experimental
