Detailed Description

Interface for token streams. See MCToken.h for token definitions used. Used to read/write tokenized data files (as are standard for Carrara) as in the following simple example, which reads in the position of a vertex:

    MCCOMErr ReadVertex(IShTokenStream* inStream,int8 *token, I3DExVertex* vertex)
    {
                ThrowIfNil(vertex);
                stream->GetNextToken(token);
                if (token[0] != tBEGIN)
                {
                        return MC_ERROR_FILE_NOT_FOUND;
                }
                stream->GetNextToken(token);
                int32 key;
                TVector3 position = TVector3::kZero;
                while (!stream->IsEndToken(token))
                {
                        stream->CompactAttribute(token,&key);
                        switch (key)
                        {
                                case 'posi':
                                        stream->GetPoint3D(&(position.x), &(position.y), &(position.z))
                                        break;
                                default:
                                        stream->SkipTokenData();
                                        break;
                        }
                        stream->GetNextToken(token);
                }
                vertex->SetPosition(position);
        }

Before reading or writing a new file, call InitTokenMgr() to initialize various variables (such as indentation size).

To read and write binary data in a tokenized text file, we must encode them as text. BeginBufferAsBinHex(), PutBufferAsBinHex(), GetBufferAsBinHex(), and EndPutBufferAsBinHex() handle this functionality.

Member Function Documentation

virtual void MCCOMAPI IShTokenStream::BeginBufferAsBinHex (  uint32 &  lastInfo  )  [pure virtual]

Initialise the saving of a binary buffer into a text stream. Should be called before PutBufferAsBinHex. Parameters: lastInfo  Pass this a 0. This will be used by PutBufferAsBinHex and EndBufferAsBinHex.

virtual MCCOMErr MCCOMAPI IShTokenStream::CompactAttribute (  int8 *  atoken, int32 *  keyword )  [pure virtual]

virtual void MCCOMAPI IShTokenStream::EndPutBufferAsBinHex (  uint32 &  lastInfo  )  [pure virtual]

Finish saving a binary buffer. lastInfo should come from the last call to PutBufferAsBinHex. Parameters: lastInfo  From the last PutBufferAsBinHex

virtual MCCOMErr MCCOMAPI IShTokenStream::GetArray (  int32  nb, real *  valArray )  [pure virtual]

virtual MCCOMErr MCCOMAPI IShTokenStream::GetBegin (   )  [pure virtual]

virtual void MCCOMAPI IShTokenStream::GetBufferAsBinHex (  int8 *  data, int32  count, uint32 &  lastInfo )  [pure virtual]

Load a binary buffer from a text stream. lastInfo should come from the last call to GetBufferAsBinHex or from BeginBufferAsBinHex. Parameters: data  pointer to the buffer to fill count  number of bytes to fill lastInfo  From the last GetBufferAsBinHex or BeginBufferAsBinHex call
