Methods
-
Increases the revision counter and dispatches a 'change' event.
-
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.
-
Gets a value.
Name Type Description key
string Key name.
Returns:
Value.
-
Return the
extent
of the layer orundefined
if it will be visible regardless of extent.Returns:
The layer extent.
-
Get a list of object property names.
Returns:
List of property names.
-
Return the maximum resolution of the layer.
Returns:
The maximum resolution of the layer.
-
Return the minimum resolution of the layer.
Returns:
The minimum resolution of the layer.
-
Return the opacity of the layer (between 0 and 1).
Returns:
The opacity of the layer.
-
Get an object of all property names and values.
Returns:
Object.
-
Get the version number for this object. Each time the object is modified, its version number will be incremented.
Returns:
Revision.
-
Return the associated
vectorsource
of the layer.Returns:
Source.
-
Get the style for features. This returns whatever was passed to the
style
option at construction or to thesetStyle
method.Returns:
Layer style.
-
Get the style function.
Returns:
Layer style function.
-
Return the visibility of the layer (
true
orfalse
).Returns:
The visibility of the layer.
-
Return the Z-index of the layer, which is used to order layers before rendering. The default Z-index is 0.
Returns:
The Z-index of the layer.

on(type, listener, opt_this){ol.EventsKey|Array.<ol.EventsKey>} inherited
src/ol/observable.js, line 99 -
Listen for a certain type of event.
Name Type Description type
string | Array.<string> The event type or array of event types.
listener
function The listener function.
this
Object The object to use as
this
inlistener
.Returns:
Unique key for the listener. If called with an array of event types as the first argument, the return will be an array of keys.
-

silent
boolean Update without triggering an event.
-
Set the extent at which the layer is visible. If
undefined
, the layer will be visible at all extents.Name Type Description extent
ol.Extent | undefined The extent of the layer.
-
Sets the layer to be rendered on top of other layers on a map. The map will not manage this layer in its layers collection, and the callback in
ol.Map#forEachLayerAtPixel
will receivenull
as layer. This is useful for temporary layers. To remove an unmanaged layer from the map, use#setMap(null)
.To add the layer to a map and have it managed by the map, use
ol.Map#addLayer
instead.Name Type Description map
ol.Map Map.
-
Set the maximum resolution at which the layer is visible.
Name Type Description maxResolution
number The maximum resolution of the layer.
-
Set the minimum resolution at which the layer is visible.
Name Type Description minResolution
number The minimum resolution of the layer.
-
Set the opacity of the layer, allowed values range from 0 to 1.
Name Type Description opacity
number The opacity of the layer.
-
Sets a collection of key-value pairs. Note that this changes any existing properties and adds new ones (it does not remove any existing properties).
Name Type Description values
Object.<string, *> Values.
silent
boolean Update without triggering an event.
-
Set the layer source.
Name Type Description source
ol.source.Source The layer source.
-
setStyle(style)
src/ol/layer/vector.js, line 179 -
Set the style for features. This can be a single style object, an array of styles, or a function that takes a feature and resolution and returns an array of styles. If it is
undefined
the default style is used. If it isnull
the layer has no style (anull
style), so only features that have their own styles will be rendered in the layer. Seeol.style
for information on the default style.Name Type Description style
ol.style.Style | Array.<ol.style.Style> | ol.StyleFunction | null | undefined Layer style.
-
Set the visibility of the layer (
true
orfalse
).Name Type Description visible
