| bind | | public static Scriptable bind(Context cx, Scriptable scope, String id)(Code) | | Returns the object in the scope chain that has a given property.
The order of evaluation of an assignment expression involves
evaluating the lhs to a reference, evaluating the rhs, and then
modifying the reference with the rhs value. This method is used
to 'bind' the given name to an object containing that property
so that the side effects of evaluating the rhs do not affect
which property is modified.
Typically used in conjunction with setName.
See ECMA 10.1.4

assumes that the [[Delete]] method returns a value. However,
the definition of the [[Delete]] operator (8.6.2.5) does not
define a return value. Here we assume that the [[Delete]]
method doesn't return a value.

after calling this method.
|

|
| in | | public static boolean in(Object a, Object b, Context cx)(Code) | | The in operator.
This is a new JS 1.3 language feature. The in operator mirrors
the operation of the for .. in construct, and tests whether the
rhs has the property given by the lhs. It is different from the
for .. in construct in that:
- it doesn't perform ToObject on the right hand side
- it returns true for DontEnum properties.
Parameters:
a - the left hand operand
Parameters:
b - the right hand operand true if property name or element number a is a property of b |

the version called from new code.
