Interface ScriptArray<T>

All Known Subinterfaces:

HTMLSelectElement

public interface ScriptArray<T>

A class implements this interface to signal that it is suitable to javascript-array notation: array[index] = value; value = array[index]; Whether array-notation really works depends on the script engine and will need some additional adaptation. This interface only signals that the class wants to have array notation.
