classOwnKeys Available since v0.9

Returns property keys that are defined target class's prototype. It accepts the following arguments:

  • target: ConstructorOrAbstractConstructor - The target class
  • recursive: boolean = false - (optional) If true, then target's prototype chain is traversed and all property keys are returned.
import { classOwnKeys } from '@aedart/support/reflections';

class A {
    foo() {}
}

class B extends A {
    get bar() {}
}

classOwnKeys(B); // [ 'constructor', 'bar' ]
classOwnKeys(B, true); // [ 'constructor', 'foo', 'bar' ]

Caution

classOwnKeys() throws TypeError if target does not have a prototype property.

Limitation

The classOwnKeys() function does not return static members of a target class.
