void PrintUsage(bool print_command_line=false)
Prints the usage documentation [provided in the constructor].
const std::vector< int32 > & GetPhones() const
Returns a sorted, unique list of phones.
int32 NumTransitionIds() const
Returns the total number of transition-ids (note, these are one-based).

The class ParseOptions is for parsing command-line options; see Parsing command-line options for more...
Definition: parse-options.h:36
void Read(std::istream &is, bool binary)
int32 NumTransitionStates() const
Returns the total number of transition-states (note, these are one-based).
int Read(int argc, const char *const *argv)
Parses the command line options and fills the ParseOptions-registered variables.
int NumArgs() const
Number of positional parameters (c.f. argc-1).
std::string GetArg(int param) const
Returns one of the positional parameters; 1-based indexing for argc/argv compatibility.
