Modifier and TypeMethod and Description
public CharacterIteratorWrapper
clone()

Overrides jdk.internal.icu.text.UCharacterIterator.clone.

Creates a clone of this iterator.

public int
current()

public int
getIndex()

Implements abstract jdk.internal.icu.text.UCharacterIterator.getIndex.

Gets the current index in text.

public int
getLength()

Implements abstract jdk.internal.icu.text.UCharacterIterator.getLength.

Returns the length of the text

public int
getText(char[] fillIn, int offset)

Implements abstract jdk.internal.icu.text.UCharacterIterator.getText.

Fills the buffer with the underlying text storage of the iterator If the buffer capacity is not enough a exception is thrown.

public int
next()

Implements abstract jdk.internal.icu.text.UCharacterIterator.next.

Returns the UTF16 code unit at index, and increments to the next code unit (post-increment semantics).

Decrement to the position of the previous code unit in the text, and return it (pre-decrement semantics).

public void
setIndex(int index)

public CharacterIteratorWrapper clone()

public int getText(char[] fillIn, int offset)

Implements abstract jdk.internal.icu.text.UCharacterIterator.getText.

Doc from jdk.internal.icu.text.UCharacterIterator.getText.

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()];
            }
        }

public int next()

Implements abstract jdk.internal.icu.text.UCharacterIterator.next.

Doc from jdk.internal.icu.text.UCharacterIterator.next.

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.

public int previous()

Implements abstract jdk.internal.icu.text.UCharacterIterator.previous.

Doc from jdk.internal.icu.text.UCharacterIterator.previous.

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.

public void setIndex(int index)

Implements abstract jdk.internal.icu.text.UCharacterIterator.setIndex.

Sets the index to the specified index in the text.
