Examples of java.text.CharacterIterator.first()

java.text.CharacterIterator.first()
Sets the position to getBeginIndex() and returns the character at that position. @return the first character in the text, or DONE if the text is empty @see #getBeginIndex()


            int sz = iter.getEndIndex()-iter.getBeginIndex();
            if (sz == 0) return;


            char[] cbuff = new char[sz];
            cbuff[0] = iter.first();
            for (int i=1; i<cbuff.length;++i) {
                cbuff[i] = iter.next();
            }
            final String strSel = new String(cbuff);
            // HACK: getSystemClipboard sometimes deadlocks on
