  • Method Details

    • reset

      public CharsTrie.Iterator reset()
      Resets this iterator to its initial state.
      Returns:
      this
    • hasNext

      public boolean hasNext()
      Specified by:
      hasNext in interface Iterator<CharsTrie.Entry>
      Returns:
      true if there are more elements.
    • next

      public CharsTrie.Entry next()
      Finds the next (string, value) pair if there is one. If the string is truncated to the maximum length and does not have a real value, then the value is set to -1. In this case, this "not a real value" is indistinguishable from a real value of -1.
      Specified by:
      next in interface Iterator<CharsTrie.Entry>
      Returns:
      An Entry with the string and value of the next element.
      Throws:
      NoSuchElementException - - iteration has no more elements.
    • remove

      public void remove()
      Iterator.remove() is not supported.
      Specified by:
      remove in interface Iterator<CharsTrie.Entry>
      Throws:
      UnsupportedOperationException - (always)
