public interface PropHolder<T extends PropHolder<T>>

Interface the common route of JS objects and environment records, i.e. a thing that has properties and some form of ancestor. Although environment records do not hold user accessible keys which are symbols or numbers, it is useful to include these as it makes the concrete map implementations simpler and they may be useful for internally maintained vbalues.

getAncestor

T getAncestor()

Get the parent scope of the object.

Returns:

the parent scope

getIds

Object[] getIds()
