OK, any idea on how to hide properties on instantiated objects? I
tried hiding the properties on the prototype, but that has no effect.
Hiding the property inside the constructor seems to make it null:
var hide = function (o, p) {
java.lang.Class.forName("org.mozilla.javascript.ScriptableObject")
.getMethod("setAttributes", java.lang.String,
java.lang.Integer.TYPE)
.invoke(o, p, new java.lang.Integer(
org.mozilla.javascript.ScriptableObject.DONTENUM));
}
function Test (){
hide(this,"doStuff")
}
Test.prototype.doStuff=function(){ return "stuff"}
new Test().doStuff();
//TypeError: Cannot call property doStuff in object [object Object].
It is not a function, it is "object".
Is it possible to make instance functions non-enumerable?
Thanks,
Mark
