TerminalConfiguration

AMD: require(["esri/networks/support/TerminalConfiguration"], (TerminalConfiguration) => { /* code goes here */ });
ESM: import TerminalConfiguration from "@arcgis/core/networks/support/TerminalConfiguration";
Class: esri/networks/support/TerminalConfiguration
Inheritance: TerminalConfiguration Accessor
Since: ArcGIS API for JavaScript 4.20

A device feature can be assigned a terminal configuration which could have one or more terminals. The terminal configuration defines the terminals and the permissable paths between them. For example, a device feature could have a Dual Terminal configuration which has a High and a Low terminal. A downstream trace starting from High side terminal will return the Low side terminal however the same trace starting from the Low side terminal won't return the High side terminal.

Another example, a tranformer with tri-state terminal configuration (3 terminals) H, X1, X2. The allowed paths are H->X1 and H->X2 with a default path H->X1. Running a downstream trace from the H terminal will select X1 and anything underneath it but not X2. The device path can be altered with the terminalConfiguration field.

   /   \

X1       X2

The terminal class defines terminal properties.

Method Details

addHandles(handleOrHandles, groupKey)inherited
Since: ArcGIS API for JavaScript 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 }
);

// Handle gets removed when the object is destroyed.
this.addHandles(handle);
Parameters
handleOrHandles WatchHandle|WatchHandle[]

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.

fromJSON(json){*}static

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.

Parameter
json Object

A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.
