Interface HIterator

public interface HIterator
An iterator over a collection. Iterator takes the place of
invalid @link 
Enumeration
in the Java Collections Framework. Iterators differ from enumerations in two ways:
  • Iterators allow the caller to remove elements from the underlying collection during the iteration with well-defined semantics.
  • Method names have been improved.

    Method
    Description
    boolean

  • Method Details

    • hasNext

      boolean hasNext()
      Returns true if the iteration has more elements. (In other words, returns true if next() would return an element rather than throwing an exception.)
      Returns:
      true if the iteration has more elements

    • next

      Object next()
      Returns the next element in the iteration.
      Returns:
      the next element in the iteration
      Throws:
      NoSuchElementException - if the iteration has no more elements

    • remove

      void remove()
      Removes from the underlying collection the last element returned by this iterator (optional operation). This method can be called only once per call to next().

      The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method, unless an overriding class has specified a concurrent modification policy.
