Detailed Description

JSValue is the base type for all primitives (Undefined, Null, Boolean, String, Number) and objects in ECMAScript.

Note: you should never inherit from JSValue as it is for primitive types only (all of which are provided internally by KJS). Instead, inherit from JSObject.

Member Function Documentation

bool KJS::JSValue::implementsCall ( ) const

inline

Whether or not the value implements the call() method.

If it does, this also implies this is an object, and hence it can be cast to a JSObject and the call method can be invoked

Returns

true if this is an object implementing the call() method, otherwise false
