Methods

bindTo

Stability: experimental

The bindTo method allows you to set up a two-way binding between a source and target object. The method returns an ol.ObjectAccessor with a transform method that lets you 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;
    }
  );

Parameters:

Name	Type	Argument	Description
key	string		Key name.
target	ol.Object		Target.
targetKey	string	<optional>	Target key.

on

Stability: experimental

Listen for a certain type of event.

Parameters:

Name	Type	Argument	Description
type	string | Array.<string>		The event type or array of event types.
listener	function		The listener function.
this	Object	<optional>	The object to use as this in listener.

Inherited From:

• ol.Observable#on

Source:

• observable.js, line 58

Returns:

Unique key for the listener.

Type

goog.events.Key

once

Stability: experimental

Listen once for a certain type of event.

Parameters:

Name	Type	Argument	Description
type	string | Array.<string>		The event type or array of event types.
listener	function		The listener function.
this	Object	<optional>	The object to use as this in listener.

Inherited From:

• ol.Observable#once

Source:

set

Stability: experimental

Sets a value.

Parameters:

Name	Type	Description
key	string	Key name.
value	*	Value.

Inherited From:

• ol.Object#set

Source:

• object.js, line 399

setMap

Stability: experimental

Remove the control from its current map and attach it to the new map. Subclasses may set up event handlers to get notified about changes to the map here.

Parameters:

Name	Type	Description
map	ol.Map	Map.

• ol.control.Control#setMap

Source:

• control.js, line 89

setValues

un

Stability: experimental

Unlisten for a certain type of event.

Parameters:

Name	Type	Argument	Description
type	string | Array.<string>		The event type or array of event types.
listener	function		The listener function.
this	Object	<optional>	The object to use as this in listener.

Inherited From:

• ol.Observable#un

Source:

• observable.js, line 83

unbind

Stability: experimental

Removes a binding. Unbinding will set the unbound property to the current value. The object will not be notified, as the value has not changed.

Parameters:

Name	Type	Description
key	string	Key name.

Parameters:

Name	Type	Description
key	goog.events.Key	Key.
