isTypeObject

  • Edit on GitHub

Determines if an object is a TypeObject.

type.isTypeObject(Type)

Given a Type, determines if it fits the TypeObject protocol. To be a TypeObject, a Type needs to be an object which contains the following symbols:

  • Symbol.for("can.new")
  • Symbol.for("can.isMember")
import { ObservableObject, type } from "can/everything";

class Faves extends ObservableObject {}

console.log("An Typed Observable", type.isTypeObject(faves)); // true

console.log("A custom TypeObject", type.isTypeObject({
  [Symbol.for("can.new")]() {},
  [Symbol.for("can.isMember")]() {}
})); // -> true

console.log("A primitive", type.isTypeObject(null)); // -> false

Parameters

  1. Type {*}:

    Anything, but usually an object of some sort.

Returns

{Boolean}:

true if it conforms to the TypeObject protocol, otherwise false.
