Member Function Documentation

addSDESItem()

void inet::rtp::SdesChunk::addSDESItem ( SdesItem *  item )

virtual

Adds an SdesItem to this SdesChunk.

If there is already an SdesItem of the same type in this SdesChunk it is replaced by the new one.

{
    for (int i = 0; i < size(); i++) {
        if (exist(i)) {
            SdesItem *compareItem = check_and_cast<SdesItem *>(get(i));
            if (compareItem->getType() == sdesItem->getType()) {
                remove(compareItem);
                _length = _length - compareItem->getSdesTotalLength();
                delete compareItem;
            }
        }
    }
 
//    sdesItem->setOwner(this);
    add(sdesItem);
    _length += sdesItem->getSdesTotalLength();
}

        return *this;
    cArray::operator=(sdesChunk);
    copy(sdesChunk);
    return *this;
