Method

booleanisPrototypePropertyGet(PropertyGet pg)
is Prototype Property Get 
return pg != null && pg.getLeft() instanceof Name && isPrototypeNameNode(pg.getRight());
booleanisSimplePropertyGet(PropertyGet pg, String expectedObj, String expectedField)
Returns whether a PropertyGet is a simple one, referencing an object's value 1 level deep. 
return pg != null && isName(pg.getLeft(), expectedObj) && isName(pg.getRight(), expectedField);
booleanisStaticProperty(Scriptable property)

Replies true if the mixin property propert is a "static" property.

Object isStatic = ((Scriptable) property).get("static", (Scriptable) property);
return isStatic != Scriptable.NOT_FOUND && isStatic instanceof Boolean && ((Boolean) isStatic);
booleanisValid(Object[] args)
is Valid 
return args.length > 0 && args[0] != Context.getUndefinedValue();
booleanisVariable(Name name)
Check if the Name (AstNode) is a variable. 
AstNode parent = name.getParent();
if (parent instanceof InfixExpression) {
    InfixExpression ie = (InfixExpression) parent;
