Examples of org.nasutekds.server.util.SizeLimitInputStream

org.nasutekds.server.util.SizeLimitInputStream
An implementation of input stream that enforces an read size limit.

    {
      if(!streamStack.isEmpty())
      {
        // We are reading a sub sequence. Return true as long as we haven't
        // exausted the size limit for the sub sequence sub input stream.
        SizeLimitInputStream subSq = (SizeLimitInputStream)in;
        return (subSq.getSizeLimit() - subSq.getBytesRead() > 0);
      }


      return state != ELEMENT_READ_STATE_NEED_TYPE ||
          needTypeState(true, false);
    }
