## Public Types

typedef std::vector< std::string > | ArgumentList
| Type for a list of arguments.
typedef ArgumentList::const_iterator | ArgumentListIt
| Iterator into ArgumentList.

## Public Member Functions

const ArgumentList & | extra_args () const
| Get reference to list of command line arguments past the last flag and its possible argument.
| operator void * () const
| Return truthy value if command line was parsed successfully.

## Protected Member Functions

| CommandLineBase (int argc, char *const argv[], const char *opts)
| Hidden ctor to prevent instantiation.
virtual | ~CommandLineBase ()
| Hidden dtor to prevent instantiation.
void | finish_parse ()
| If object is still marked as "successful", save non-option arguments to extra_args_ list. Subclass ctor should call this after the parse_next() loop gets EOF.
const char * | option_argument () const
| Accessor for getopt()'s optarg global.
int | option_index () const
| Accessor for getopt()'s optind global.
void | parse_error (const char *message=0)
| Called by a subclass when encountering a command line parsing error.
int | parse_next () const
| Wrapper for getopt().
virtual void | print_usage () const =0
| Show a message explaining the program's proper usage.
const char * | program_name () const
| Get the file name of the program's executable.
bool | successful () const
| Returns true if nothing has gone wrong since calling the ctor.

## Detailed Description

Parses command line arguments and holds the results.

Subclass interface

## Member Function Documentation

const ArgumentList& mysqlpp::CommandLineBase::extra_args | ( |  | ) | const`[inline]`

Get reference to list of command line arguments past the last flag and its possible argument.

Public interface

void mysqlpp::CommandLineBase::parse_error | ( | const char * | message = `0` | ) | `[protected]`

Called by a subclass when encountering a command line parsing error.

Prints the passed message, calls subclass's print_usage(), and marks the object as no longer successful.
