Documentation

Handles the standard binary sequence format in Torch. The format is the following:

o IOBin(const char* filename_, bool one_file_is_one_sequence_=false, int max_load_=-1, bool is_sequential=true)
Reads the sequence contained in filename. If one_file_is_one_sequence is false, getSequence() will return one sequence with one frame at each call. (If calling getSequence(t, foo), it will put in the sequence foo the frame corresponding to the line t of the file). Note also that if one_file_is_one_sequence is false, the access to the IO must be sequential when calling getSequence() if is_sequential is true. (Sequential mode is faster). If max_load_ is positive, it loads only the first max_load_ frames, if one_file_is_one_sequence is false. The file will be opened when reading the first sequence, and closed when reading the last one if is_sequential is true. Otherwise, the file will be opened and closed each time you call getSequence().

ostatic void saveSequence(XFile* file, Sequence* sequence)
Saves sequence in file using the binary format
