int LwoGroupChunk::get_num_chunks (   )  const [inherited]

Returns the number of child chunks of this group. Definition at line 38 of file lwoGroupChunk.cxx. References LwoGroupChunk::_chunks, nassertr, and NULL.

virtual TypeHandle LwoGroupChunk::get_type (  void   )  const [inline, virtual, inherited]

Reimplemented from LwoChunk. Reimplemented in LwoClip, LwoHeader, LwoSurface, LwoSurfaceBlockHeader, and LwoSurfaceBlockTMap. Definition at line 57 of file lwoGroupChunk.h. References LwoGroupChunk::_type_handle, LwoChunk::init_type(), and register_type().

IffChunk * LwoSurfaceBlock::make_new_chunk (  IffInputFile *  in, IffId  id )  [virtual]

Allocates and returns a new chunk of the appropriate type based on the given ID, according to the context given by this chunk itself. Reimplemented from IffChunk. Definition at line 104 of file lwoSurfaceBlock.cxx.

void IffChunk::output (  ostream &  out  )  const [virtual, inherited]

Definition at line 37 of file iffChunk.cxx. References IffChunk::_id, and indent().

bool LwoGroupChunk::read_chunks_iff (  IffInputFile *  in, size_t  stop_at )  [protected, inherited]

Reads a sequence of child chunks, until byte stop_at has been been reached, and stores them as the children. Returns true if successful (and exactly the correct number of bytes were read), or false otherwise. Definition at line 73 of file lwoGroupChunk.cxx. References LwoGroupChunk::_chunks, IffInputFile::get_bytes_read(), IffInputFile::get_subchunk(), IffInputFile::is_eof(), NULL, and PT.

bool LwoSurfaceBlock::read_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. Implements IffChunk. Definition at line 57 of file lwoSurfaceBlock.cxx.

bool LwoGroupChunk::read_subchunks_iff (  IffInputFile *  in, size_t  stop_at )  [protected, inherited]

void IffChunk::set_id (  IffId  id  )  [inline, inherited]

Changes the ID associated with this chunk. Definition at line 56 of file iffChunk.I.

void LwoSurfaceBlock::write (  ostream &  out, int  indent_level = 0 )  const [virtual]

Reimplemented from IffChunk. Definition at line 81 of file lwoSurfaceBlock.cxx.

void LwoGroupChunk::write_chunks (  ostream &  out, int  indent_level )  const [protected, inherited]

Formats the list of chunks for output to the user (primarily for debugging), one per line. Definition at line 119 of file lwoGroupChunk.cxx. Referenced by LwoSurfaceBlockTMap::read_iff(), LwoSurface::read_iff(), and LwoClip::read_iff().
