Warning sign
Warning: JSObjectOps is not a supported API. Details of the API may change from one release to the next. This documentation should be considered SpiderMonkey internals documentation, not API documentation. See bug 408416 .

The JSObjectOps.setProto and setParent callbacks implement the JS_SetPrototype and JS_SetParent functions. These callbacks share the same type, JSSetObjectSlotOp.

Syntax 

typedef JSBool (*JSSetObjectSlotOp)(JSContext *cx, JSObject *obj,
    uint32 slot, JSObject *pobj);
Name Type Description
cx JSContext * Pointer to the JS context in which the object's prototype or parent is being modified.
obj JSObject * The object whose prototype or parent is being modified.
slot uint32 The index of the slot being modified: JSSLOT_PROTO for the JSObjectOps.setProto callback, and JSSLOT_PARENT for the JSObjectOps.setParent callback.
pobj JSObject * The new prototype or parent object.

Description

These hooks must check for cycles without deadlocking, and otherwise take special steps. See js_SetPrototype or js_SetParent in js/src/jsobj.c for an example.
