Detailed Description

A multimap-like container for command-line options and their values.

The values are G::OptionValue objects, so they can be valued with a string value or unvalued with an on/off status, and they can have a repeat-count. Normally populated by G::OptionParser.

Member Function Documentation

◆ begin()

G::OptionMap::const_iterator G::OptionMap::begin ( ) const

Returns the begin iterator.

Definition at line 44 of file goptionmap.cpp.

◆ cbegin()

G::OptionMap::const_iterator G::OptionMap::cbegin ( ) const

Returns the begin iterator.

Definition at line 49 of file goptionmap.cpp.

◆ cend()

G::OptionMap::const_iterator G::OptionMap::cend ( ) const

Returns the off-the-end iterator.

Definition at line 59 of file goptionmap.cpp.

◆ clear()

void G::OptionMap::clear ( )

Clears the map.

Definition at line 69 of file goptionmap.cpp.

◆ contains() [1/2]

bool G::OptionMap::contains ( const char *  key) const

Overload taking a c-string.

Definition at line 74 of file goptionmap.cpp.

◆ contains() [2/2]

bool G::OptionMap::contains ( const std::string &  key) const

Returns true if the map contains the given key, but ignoring 'off' option-values.

Definition at line 79 of file goptionmap.cpp.

◆ count()

std::size_t G::OptionMap::count ( const std::string &  key) const

Returns the total repeat count for all matching entries.

See G::OptionValue::count().

Definition at line 91 of file goptionmap.cpp.

◆ end()

G::OptionMap::const_iterator G::OptionMap::end ( ) const

Returns the off-the-end iterator.

Definition at line 54 of file goptionmap.cpp.

◆ find()

G::OptionMap::const_iterator G::OptionMap::find ( const std::string &  key) const

Finds the map entry with the given key.

Definition at line 64 of file goptionmap.cpp.

◆ increment()

void G::OptionMap::increment ( const std::string &  key)

Increments the repeat count for the given entry.

Definition at line 37 of file goptionmap.cpp.

◆ insert()

void G::OptionMap::insert ( const Map::value_type &  value)

Inserts the key/value pair into the map.

The ordering of values in the map with the same key is in the order of insert()ion.

Definition at line 24 of file goptionmap.cpp.

◆ replace()

void G::OptionMap::replace ( const std::string &  key,
const std::string &  value 
)

Replaces all matching values with a single value.

Definition at line 29 of file goptionmap.cpp.

◆ value() [1/2]

std::string G::OptionMap::value ( const char *  key,
const char *  default_ = nullptr 
) const

Overload taking c-strings.

Definition at line 100 of file goptionmap.cpp.

◆ value() [2/2]

std::string G::OptionMap::value ( const std::string &  key,
const std::string &  default_ = std::string() 
) const

Returns the matching value, with concatentation into a comma-separated list if multivalued.

If there are any on/off option-values matching the key then a single value is returned corresponding to the first one, being G::Str::positive() if 'on' or the supplied default if 'off'.
