Class XYZ

Classdesc

Layer source for tile data with URLs in a set XYZ format that are defined in a URL template. By default, this follows the widely-used Google grid where x 0 and y 0 are in the top left. Grids like TMS where x 0 and y 0 are in the bottom left can be used by using the {-y} placeholder in the URL template, so long as the source does not have a custom tile grid. In this case, ol.source.TileImage can be used with a tileUrlFunction such as:

tileUrlFunction: function(coordinate) { return 'http://mapserver.com/' + coordinate[0] + '/' + coordinate[1] + '/' + coordinate[2] + '.png'; }

Param: opt_options

XYZ options.

    Revision.

    Api

getState

getTileGrid

getTileLoadFunction

getTileUrlFunction

getUrls

  • getUrls(): string[]

  • Return the URLs used for this source. When a tileUrlFunction is used instead of url or urls, null will be returned.

    Returns string[]

    URLs.

    Api

on

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

  • Listen 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[]

    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.

    Api

    stable

once

  • 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.

    • listener: Function

      The listener function.

    • Optional opt_this: Object

      The object to use as this in listener.

    Returns Object | Object[]

    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.

    Api

    stable

refresh

  • refresh(): void

  • Refreshes the source and finally dispatches a 'change' event.

    Returns void

    Api

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

  • setAttributions(attributions): void

  • Set the attributions of the source.

    Parameters

    • attributions: AttributionLike

      Attributions. Can be passed as string, Array<string>, {@link ol.Attribution}, Array<{@link ol.Attribution}> or undefined.

    Returns void

    Api

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).
