getClassPropertyDescriptors Available since v0.9

Returns all property descriptors that are defined target's prototype.

It accepts the following arguments:

• target: ConstructorOrAbstractConstructor - The target class.
• recursive: boolean = false - (optional) If true, then target's parent prototypes are traversed. Descriptors are merged, such that the top-most class' descriptors are returned.

import { getClassPropertyDescriptors } from '@aedart/support/reflections';

class A {
    set name(v) {}
    get name() {}
    bar() {}
    [MY_SYMBOL]() {}
}

getClassPropertyDescriptors(A); // { bar: {...}, name: {...}, [MY_SYMBOL]: {...} }

When recursive is set to true, then all property descriptors are returned from the target class' prototype chain.

import { getClassPropertyDescriptors } from '@aedart/support/reflections';

class A {
    set name(v) {}
    get name() {}
    foo() {}
    [MY_SYMBOL]() {}
}

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

getClassPropertyDescriptors(B, true);
// { bar: {...}, foo: {...}, name: {...}, [MY_SYMBOL]: {...} }

Caution

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