Member Function Documentation

◆ scope()

const ScopeChain& KJS::FunctionImp::scope ( ) const
inline

Returns the scope of this object.

This is used when execution declared functions - the execution context for the function is initialized with extra object in its scope. An example of this is functions declared inside other functions:

function f() {
function b() {
return prototype;
}
var x = 4;
// do some stuff
}
f.prototype = new String();

When the function f.b is executed, its scope will include properties of f. So in the example above the return value of f.b() would be the new String object that was assigned to f.prototype.

Parameters
execThe current execution state
Returns
The function's scope
