The Reflect API is a way to manipulate values dynamically through an abstract interface in an untyped manner. Use with care.

See:

Static methods

staticcopy<T> (o:T):T

Copies the fields of structure o.

This is only guaranteed to work on anonymous structures.

If o is null, the result is unspecified.

staticfield (o:Dynamic, field:String):Dynamic

Returns the value of the field named field on object o.

If o is not an object or has no field named field, the result is null.

If the field is defined as a property, its accessors are ignored. Refer to Reflect.getProperty for a function supporting property accessors.

If field is null, the result is unspecified.

(As3) If used on a property field, the getter will be invoked. It is not possible to obtain the value directly.

@:has_untypedstaticfields (o:Dynamic):Array<String>

Returns the fields of structure o.

This method is only guaranteed to work on anonymous structures. Refer to Type.getInstanceFields for a function supporting class instances.

If o is null, the result is unspecified.

@:access(js.Boot)staticisFunction (f:Dynamic):Bool

Returns true if f is a function, false otherwise.

If f is null, the result is false.

@:has_untypedstaticsetProperty (o:Dynamic, field:String, value:Dynamic):Void

Sets the field named field of object o to value value, taking property setter functions into account.

If the field is not a property, this function behaves like Reflect.setField, but might be slower.

If field is null, the result is unspecified.
