    • Method Detail

      • createEnumerator

        public static java.util.Enumeration<?> createEnumerator​(java.util.Iterator<?> iterator)
        Creates an instance of the Enumeration interface from an Iterator.
        Parameters:
        iterator - The Iterator instance.
        Returns:
        A new Enumeration instance.

      • hasMoreElements

        public boolean hasMoreElements()
        Returns true if the enumeration has more elements. (In other words, returns true if nextElement would return an element rather than throwing an exception.)
        Specified by:
        hasMoreElements in interface java.util.Enumeration<T>
        Returns:
        true if the enumerator has more elements.

      • nextElement

        public T nextElement()
        Returns the next element in the enumeration.
        Specified by:
        nextElement in interface java.util.Enumeration<T>
