Examples of com.ibm.icu.text.BreakIterator.first()

com.ibm.icu.text.BreakIterator.first()
Return the first boundary position. This is always the beginning index of the text this iterator iterates over. For example, if the iterator iterates over a whole string, this function will always return 0. This function also updates the iteration position to point to the beginning of the text. @return The character offset of the beginning of the stretch of textbeing broken. @stable ICU 2.0

    // compile against JCL Foundation (bug 80053).
    // Also need to do this in an NL-sensitive way. The use of BreakIterator
    // was suggested in bug 90579.
    BreakIterator iter = BreakIterator.getWordInstance();
    iter.setText(text);
    int i = iter.first();
    while (i != java.text.BreakIterator.DONE && i < text.length()) {
      int j = iter.following(i);
