Protected Member Functions

bool read_chunks_iff (IffInputFile *in, size_t stop_at)
 Reads a sequence of child chunks, until byte stop_at has been been reached, and stores them as the children.

bool read_subchunks_iff (IffInputFile *in, size_t stop_at)
 Similar to read_chunks_iff(), but reads them as subchunks.

void write_chunks (ostream &out, int indent_level) const
 Formats the list of chunks for output to the user (primarily for debugging), one per line.

bool LwoGroupChunk::read_chunks_iff (  IffInputFile *  in,

size_t  stop_at
)  [virtual]
 

Reads the data of the chunk in from the given input file, if possible.

The ID and length of the chunk have already been read. stop_at is the byte position of the file to stop at (based on the current position at in->get_bytes_read()). Returns true on success, false otherwise.
