TimeInfo | API Reference | ArcGIS Maps SDK for JavaScript 4.33

ESM: import TimeInfo from "@arcgis/core/layers/support/TimeInfo.js";

CDN: const TimeInfo = await $arcgis.import("@arcgis/core/layers/support/TimeInfo.js");

Class: @arcgis/core/layers/support/TimeInfo

Since: ArcGIS Maps SDK for JavaScript 4.11

Time info represents the temporal data of a time-aware layer. The time info class provides information such as date fields that store the start and end times for each feature and the total time span for the layer.

Temporal data is data that represents a state in time. You can to step through periods of time to reveal patterns and trends in your data. With temporal data, you can visualize and analyze:

• Moving objects (e.g. planes, satellites, storms),
• Events (e.g. accidents or earthquakes),
• Sensor data (e.g. stream gauges, weather station readings), or
• Variable characteristics (e.g. national or regional population).

TimeInfo Constructor new TimeInfo(properties)

Parameter

optional

See the properties for a list of all the properties that may be passed into the constructor.

declaredClass

Inherited

Property declaredClass Stringreadonly

The name of the class. The declared class name is formatted as esri.folder.className.

Since: ArcGIS Maps SDK for JavaScript 4.12 TimeInfo since 4.11, fullTimeExtent added at 4.12.

The time extent defines the start time and end time for all data in the layer.

Example

const { start, end } = featureLayer.timeInfo.fullTimeExtent;
const range = end - start;  // milliseconds
const days = range / ( 1000 * 60 * 60 * 24 ); // days
console.log(`The layer's temporal extent is ${days} days.`);

Since: ArcGIS Maps SDK for JavaScript 4.12 TimeInfo since 4.11, interval added at 4.12.

The time interval defines the granularity of the temporal data and allows you to visualize the data at specified intervals using the time slider widget. Usually temporal data is collected at regular intervals such as every hour or every day.

Since: ArcGIS Maps SDK for JavaScript 4.30 TimeInfo since 4.11, stops added at 4.30.

Indicates the time instants that the layer has data for. Used in place of interval, etc.

Since: ArcGIS Maps SDK for JavaScript 4.28 TimeInfo since 4.11, timeZone added at 4.28.

The IANA time zone that dates are stored in. This only applies to startField and endField.

Since: ArcGIS Maps SDK for JavaScript 4.15 TimeInfo since 4.11, trackIdField added at 4.15.

The name of the field used to join or group discrete locations. For example, for hurricane tracks, trackIdField can be the hurricane name field.

addHandles

Inherited

Method addHandles(handleOrHandles, groupKey)

Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();

Parameters

Handles marked for removal once the object is destroyed.

groupKey *

optional

Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

clone Method clone(){this}

Creates a deep clone of this object. Any properties that store values by reference will be assigned copies of the referenced values on the cloned instance.

Returns

Type Description this A deep clone of the class instance that invoked this method.

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Returns

Type Description * | null | undefined Returns a new instance of this class.

hasHandles

Inherited

Method hasHandles(groupKey){Boolean}

Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, hasHandles added at 4.25.

Returns true if a named group of handles exist.

Parameter

groupKey *

optional

A group key.

Returns

Type Description Boolean Returns true if a named group of handles exist.

Example

// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

removeHandles

Inherited

Method removeHandles(groupKey)

Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, removeHandles added at 4.25.

Removes a group of handles owned by the object.

Parameter

groupKey *

optional

A group key or an array or collection of group keys to remove.

Example

obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");
