The delete operator See ECMA 11.4.1 In ECMA 0.19, the description of the delete operator (11.4.1) 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.

name

public static Object name(Context cx,

bind

public static Scriptable bind(Context cx,

Returns the object in the scope chain that has a given property.

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

public static Callable getPropFunctionAndThis(Object obj,
 String property,
 Context cx,
 Scriptable scope)

Prepare for calling obj.property(...): return function corresponding to obj.property and make obj properly converted to Scriptable available as ScriptRuntime.lastStoredScriptable() for consumption as thisObj.

- it doesn't perform ToObject on the right hand side
- it returns true for DontEnum properties.

Parameters:

a - the left hand operand

b - the right hand operand

Returns:

true if property name or element number a is a property of b
