    • current

      public int current()
      Description copied from class: UCharacterIterator
      Returns the code unit at the current index. If index is out of range, returns DONE. Index is not changed.
      Specified by:
      current in class UCharacterIterator
      Returns:
      current code unit

    • getLength

      public int getLength()
      Description copied from class: UCharacterIterator
      Returns the length of the text
      Specified by:
      getLength in class UCharacterIterator
      Returns:
      length of the text
      See Also:

    • getIndex

      public int getIndex()
      Description copied from class: UCharacterIterator
      Gets the current index in text.
      Specified by:
      getIndex in class UCharacterIterator
      Returns:
      current index in text.
      See Also:

    • next

      public int next()
      Description copied from class: UCharacterIterator
      Returns the UTF16 code unit at index, and increments to the next code unit (post-increment semantics). If index is out of range, DONE is returned, and the iterator is reset to the limit of the text.
      Specified by:
      next in interface UForwardCharacterIterator
      Specified by:
      next in class UCharacterIterator
      Returns:
      the next UTF16 code unit, or DONE if the index is at the limit of the text.
      See Also:

    • previous

      public int previous()
      Description copied from class: UCharacterIterator
      Decrement to the position of the previous code unit in the text, and return it (pre-decrement semantics). If the resulting index is less than 0, the index is reset to 0 and DONE is returned.
      Specified by:
      previous in class UCharacterIterator
      Returns:
      the previous code unit in the text, or DONE if the new index is before the start of the text.
      See Also:

    • setIndex

      public void setIndex(int index)
      Description copied from class: UCharacterIterator
      Sets the index to the specified index in the text.
      Specified by:
      setIndex in class UCharacterIterator
      Parameters:
      index - the index within the text.
      See Also:

    • setToLimit

      public void setToLimit()
      Description copied from class: UCharacterIterator
      Sets the current index to the limit.
      Overrides:
      setToLimit in class UCharacterIterator
      See Also:

    • getText

      public int getText(char[] fillIn, int offset)
      Description copied from class: UCharacterIterator
      Fills the buffer with the underlying text storage of the iterator If the buffer capacity is not enough a exception is thrown. The capacity of the fill in buffer should at least be equal to length of text in the iterator obtained by calling getLength()). Usage: 
               UChacterIterator iter = new UCharacterIterator.getInstance(text);
         char[] buf = new char[iter.getLength()];
         iter.getText(buf);

         OR
         char[] buf= new char[1];
         int len = 0;
         for(;;){
             try{
                 len = iter.getText(buf);
                 break;
             }catch(IndexOutOfBoundsException e){
                 buf = new char[iter.getLength()];
             }
         }
      Specified by:
      getText in class UCharacterIterator
      Parameters:
      fillIn - an array of chars to fill with the underlying UTF-16 code units.
      offset - the position within the array to start putting the data.
      Returns:
      the number of code units added to fillIn, as a convenience
      See Also:

    • clone

      public Object clone()
      Creates a clone of this iterator. Clones the underlying character iterator.
      Overrides:
      clone in class UCharacterIterator
      Returns:
      copy of this iterator
      See Also:

    • moveIndex

      public int moveIndex(int delta)
      Description copied from class: UCharacterIterator
      Moves the current position by the number of code units specified, either forward or backward depending on the sign of delta (positive or negative respectively). If the resulting index would be less than zero, the index is set to zero, and if the resulting index would be greater than limit, the index is set to limit.
      Overrides:
      moveIndex in class UCharacterIterator
      Parameters:
      delta - the number of code units to move the current index.
      Returns:
      the new index.

    • getCharacterIterator

      public CharacterIterator getCharacterIterator()
      Description copied from class: UCharacterIterator
      Returns a java.text.CharacterIterator object for the underlying text of this iterator. The returned iterator is independent of this iterator.
      Overrides:
      getCharacterIterator in class UCharacterIterator
      Returns:
      java.text.CharacterIterator object
