All Implemented Interfaces:

public final class UCharArrayIterator extends UCharacterIterator

  • Constructor Details

    • UCharArrayIterator

      public UCharArrayIterator(char[] text, int start, int limit)

  • Method Details

    • 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

    • 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.

    • 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.

    • 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.

    • 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.

    • 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

    • clone

      public Object clone()
      Creates a copy of this iterator, does not clone the underlying Replaceableobject
      Overrides:
      clone in class UCharacterIterator
      Returns:
      copy of this iterator
