tyneq / reflect

Function: reflect()

reflect<T>(target, options?): ReflectionContext<T>

Defined in: src/utility/reflect.ts:236

Creates a ReflectionContext for the given target.

The target can be:

• A constructor function - reflects the class prototype (instance members). Preferred form.
• A prototype object (MyClass.prototype) - reflects it directly.
• Any object - reflects the object's own properties directly.

Type Parameters

Type Parameter
T extends object

Parameters

Parameter	Type
target	T | (...args) => T
options	ReflectOptions

Returns

ReflectionContext<T>

Example

import { reflect } from "tyneq/utility";

class Service {
    public name = "svc";
    public get label(): string { return this.name; }
    public run(): void { /* ... */ }
}

const ctx = reflect(Service);

ctx.methods();   // -> [{ kind: "method", name: "run", ... }]
ctx.accessors(); // -> [{ kind: "accessor", name: "label", canRead: true, canWrite: false, ... }]

const m = ctx.getMethod("run");
m.invoke(new Service()); // calls run()

Walk the full prototype chain:

const ctx = reflect(DerivedClass, { inherited: true });
ctx.members(); // includes members from base classes too
