Class Vector

Classdesc

Vector data that is rendered client-side. Note that any property set in the options is set as a ol.Object property on the layer object; for example, setting title: 'My Title' in the options means that title is observable, and has get/set accessors.

Fires

Param: opt_options

    Observable

    Api

on

  • on(type, listener, opt_this?): Object | Object[]

      The listener function.

    • Optional opt_this: Object

      The object to use as this in listener.

    Returns Object | Object[]

  • once(type, listener, opt_this?): Object | Object[]

  • Listen once for a certain type of event.

    Parameters

    • type: string | string[]

      The event type or array of event types.

      The listener function.

    • Optional opt_this: Object

      The object to use as this in listener.

    Returns Object | Object[]

    Api

    stable

set

  • set(key, value, opt_silent?): void

  • Sets a value.

    Parameters

    • key: string

      Key name.

    • value: any

      Value.

    • Optional opt_silent: boolean

      Update without triggering an event.

    Returns void

    Api

    stable

setExtent

  • setExtent(extent): void

  • Set the extent at which the layer is visible. If undefined, the layer will be visible at all extents.

    Parameters

    • extent: Extent

      The extent of the layer.

    Returns void

    Observable

    Api

    stable

setMap

  • setMap(map): void

  • 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 receive null 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.

    Parameters

    Returns void

    Api

setMaxResolution

  • setMaxResolution(maxResolution): void

  • Set the maximum resolution at which the layer is visible.

    Parameters

    • maxResolution: number

      The maximum resolution of the layer.

    Returns void

    Observable

    Api

    stable

setMinResolution

  • setMinResolution(minResolution): void

  • Set the minimum resolution at which the layer is visible.

    Parameters

    • minResolution: number

      The minimum resolution of the layer.

    Returns void

    Observable

    Api

    stable

setOpacity

  • setOpacity(opacity): void

  • Set the opacity of the layer, allowed values range from 0 to 1.

    Parameters

    • opacity: number

      The opacity of the layer.

    Returns void

    Observable

    Api

    stable

setProperties

  • setProperties(values, opt_silent?): void

  • 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).

    Parameters

    • values: {
          [k: string]: any;
      }

      Values.

      • [k: string]: any

      The layer source.

    Returns void

    Observable

    Api

    stable

setStyle

  • setStyle(style): void

  • 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 is null the layer has no style (a null style), so only features that have their own styles will be rendered in the layer. See ol.style for information on the default style.

    Parameters

    Returns void

    Api

    stable

setVisible

  • setVisible(visible): void

  • Set the visibility of the layer (true or false).

    Parameters

    Returns void

    Observable

    Api

setZIndex

  • setZIndex(zindex): void

  • Set Z-index of the layer, which is used to order layers before rendering. The default Z-index is 0.

    Parameters

    • zindex: number

      The z-index of the layer.

    Returns void

    Observable

    Api

un

  • un(type, listener, opt_this?): void

  • Unlisten for a certain type of event.

    Parameters

    • type: string | string[]

      The event type or array of event types.

    • listener: Function

      The listener function.

    • Optional opt_this: Object

      The object which was used as this by the listener.

    Returns void

    Api

    stable
