JSVAL_IS_OBJECT

Obsolete since JSAPI 32
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Determine whether a given jsval is an object or null.

Syntax

JSBool
JSVAL_IS_OBJECT(jsval v);

Description

JSVAL_IS_OBJECT(v) returns true if v is either an object or JSVAL_NULL. This indicates that it is safe to call JSVAL_TO_OBJECT(v) to convert v to type JSObject *. If v is a string, number, boolean, or undefined, the result is false.

This function is obsolete and has been removed. Instead use !JSVAL_IS_PRIMITIVE(v) to detect objects and JSVAL_IS_NULL(v) to detect null.
