JS SetParent

From MDC

Sets the parent for an object.

[edit] Syntax

JSBool JS_SetParent(JSContext *cx, JSObject *obj, JSObject *parent);

Name	Type	Description
cx	JSContext *	Pointer to a JS context from which to derive runtime information. Requires request. (In a JS_THREADSAFE build, the caller must be in a request on this JSContext.)
obj	JSObject *	Pointer to the object for which to set the parent.
parent	JSObject *	Pointer to the parent object to use.

[edit] Description

JS_SetParent sets the parent object for a specified object. A parent object is part of the enclosing scope chain for an object. Ordinarily you set a parent for an object when you create the object with JS_NewObject, but if you do not set a parent at that time, you can later call JS_SetParent to do so.

obj is a pointer to an existing JS object, and parent is a pointer to a second existing object of which the first object is a child. If JS_SetParent is successful, it returns JS_TRUE. Otherwise, if it cannot create and fill a parent slot for the object, it returns JS_FALSE.

To get an object's parent object, use JS_GetParent.
