void 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. 

00168                                               {
00169     for (int i = 0; i < items(); i++) {
00170         if (exist(i)) {
00171             SDESItem *compareItem = (SDESItem *)(get(i));
00172             if (compareItem->type() == sdesItem->type()) {
00173                 remove(compareItem);
00174                 _length = _length - compareItem->length();
00175                 delete compareItem;
00176             };
00177         }
00178     };
00179 
00180     //sdesItem->setOwner(this);
00181     add(sdesItem);
00182     _length = _length + (sdesItem->length());
00183 
00184 };

const char * SDESChunk::className (   )  const [virtual]
 

Returns the class name "SDESChunk". 

00145                                        {
00146     return "SDESChunk";
00147 };

cObject * SDESChunk::dup (   )  const [virtual]
 

Duplicates this SDESChunk by calling the copy constructor. 

00140                               {
00141     return new SDESChunk(*this);
00142 };

std::string SDESChunk::info (   )  [virtual]
 

Writes a short info about this SDESChunk into the given string.

00151     std::stringstream out;
00152     out << "SDESChunk.ssrc=" << _ssrc << " items=" << items();
00153     return out.str();
00154 };

int SDESChunk::length (   )  [virtual]

00197                       {
00198     return _length;
00199 };

SDESChunk & SDESChunk::operator= (  const SDESChunk &  sdesChunk  )

00133     cArray::operator=(sdesChunk);
00134     _ssrc = sdesChunk._ssrc;

00158     os << "SDESChunk:" << endl;
00159     os << "  ssrc = " << _ssrc << endl;
00160     for (int i = 0; i < items(); i++) {
00161         if (exist(i)) {
00162             get(i)->writeContents(os);
00163         };
