public interface SymbolScriptable

This interface may be combined with any object that implements Scriptable to add support for properties keyed by Symbol objects (as opposed to String and number objects as in previous versions of JavaScript. It's separated into its own interface so that the addition of Symbol support does not break compatibility for existing code.

Since:

1.7.8
