        if( eventType == TEXT ) {
            if(usePC) {
                holderForStartAndLength[0] = pcStart;
                holderForStartAndLength[1] = pcEnd - pcStart;
                return pc;
            } else {
                holderForStartAndLength[0] = posStart;

                      || eventType == END_TAG
                      || eventType == CDSECT
                      || eventType == COMMENT
                      || eventType == ENTITY_REF
                      || eventType == PROCESSING_INSTRUCTION
                      || eventType == IGNORABLE_WHITESPACE
                      || eventType == DOCDECL)
        {
            holderForStartAndLength[0] = posStart;
            holderForStartAndLength[1] = posEnd - posStart;
            return buf;
        } else if(eventType == START_DOCUMENT
                      || eventType == END_DOCUMENT) {
            //throw new XmlPullParserException("no content available to 
read");
            holderForStartAndLength[0] = holderForStartAndLength[1] = 
-1;
            return null;
        } else {
            throw new IllegalArgumentException("unknown text eventType: 
"+eventType);
        }
        //      String s = getText();
        //      char[] cb = null;
        //      if(s!= null) {
        //          cb = s.toCharArray();
        //          holderForStartAndLength[0] = 0;
        //          holderForStartAndLength[1] = s.length();
        //      } else {
        //      }
        //      return cb;
    }

All these code comes unde java version of pull parser
