Detailed Description

A map class which implements many of the functions on std::map.

This is an unordered map that can be named.

We don't guarantee exact method-for-method compatibility with any of the std types.

This class gives access methods to a map from data_t to data_t.

This is moveable, but not implicitly copyable. If you want to copy it use the .copy() method. If you want to move it use std::move().

No underlying implementation of the map is guaranteed. Modifying the contents will invalidate any iterators you have and any references that you have to the underlying structure.

Constructor & Destructor Documentation

com::softwareag::connectivity::map_t::map_t ( )

inline

Construct an empty map.

com::softwareag::connectivity::map_t::map_t	(	size_t	n,
		const char *	name = `nullptr`
	)

explicit

Construct a map with (at least) capacity for n items and optional name.

com::softwareag::connectivity::map_t::map_t ( const char * name )

inlineexplicit

Construct an empty map with a name.

com::softwareag::connectivity::map_t::~map_t ( )

inline

Free the underlying map contents.

com::softwareag::connectivity::map_t::map_t ( map_t && other )

inline

Move constructor.

Other will be left as the empty map

com::softwareag::connectivity::map_t::map_t ( std::initializer_list< std::pair< data_t, data_t >> l )

inline

Initializer list construction, for example map_t{ std::make_pair(data_t{"key1"},data_t{"val1"}), std::make_pair(data_t{"key2"},data_t{"val2"}) }

Member Function Documentation

iterator com::softwareag::connectivity::map_t::begin ( )

inline

Forward iterator begin.

const_iterator com::softwareag::connectivity::map_t::begin ( ) const

inline

Forward const_iterator begin.

const_iterator com::softwareag::connectivity::map_t::cbegin ( ) const

inline

Forward const_iterator begin.

const_iterator com::softwareag::connectivity::map_t::cend ( ) const

inline

Forward const_iterator end.

void com::softwareag::connectivity::map_t::clear ( )

Empty the map, clean the name and free the underlying data.

map_t com::softwareag::connectivity::map_t::copy ( ) const

inline

Return a deep copy of this map.

bool com::softwareag::connectivity::map_t::empty ( ) const

inline

Returns true if the map is empty (size() == 0)

iterator com::softwareag::connectivity::map_t::end ( )

inline

Forward iterator end.

const_iterator com::softwareag::connectivity::map_t::end ( ) const

inline

Forward const_iterator end.

size_t com::softwareag::connectivity::map_t::erase ( const data_t & k )

Remove the item with the specified key.

Returns the number of items removed (always 1)

void com::softwareag::connectivity::map_t::erase ( iterator it )

Erase the item pointed to by this iterator.

If the iterator is end() this is a noop.

iterator com::softwareag::connectivity::map_t::find ( const data_t & k )

Searches the map for an item with the given key and returns an iterator to that position in the map.

If it is not found will return end().

const_iterator com::softwareag::connectivity::map_t::find ( const data_t & k ) const

Searches the map for an item with the given key and returns an iterator to that position in the map.

If it is not found will return end().

const char* com::softwareag::connectivity::map_t::getName ( ) const

inline

Get the optional name of this map.

Can return nullptr.

std::pair<iterator, bool> com::softwareag::connectivity::map_t::insert ( insertion_t && v )

Insert a new key/value pair into the map.

If the key already exists then the map is not modified and an iterator to the existing item is returned. Returns pair<iterator, bool> where the iterator points to the item with the given key and the boolean is true if the map needed to be modified with the new pair.

This is a move operator from the data_ts, so they will be left in the empty state. If you do not want this, use .copy(), otherwise use std::move

std::pair<iterator, bool> com::softwareag::connectivity::map_t::insert	(	data_t &&	k,
		data_t &&	v
	)

inline

Insert a new key/value pair into the map.

If the key already exists then the map is not modified and an iterator to the existing item is returned. Returns pair<iterator, bool> where the iterator points to the item with the given key and the boolean is true if the map needed to be modified with the new pair.

This is a move operator from the data_ts, so they will be left in the empty state. If you do not want this, use .copy(), otherwise use std::move

bool com::softwareag::connectivity::map_t::operator!= ( const map_t & other ) const

inline

Returns false if this map deep-equals other.

map_t& com::softwareag::connectivity::map_t::operator= ( map_t && other )

inline

Move assignment.

Other will be left as the empty map and our previous contents will be freed.

bool com::softwareag::connectivity::map_t::operator== ( const map_t & other ) const

inline

Returns true if this map deep-equals other.

data_t& com::softwareag::connectivity::map_t::operator[] ( data_t && k )

inline

Return a reference to the item with the given key.

If k is not in the map then it inserts it and returns a reference to that

data_t& com::softwareag::connectivity::map_t::operator[] ( const data_t & k )

inline

Return a reference to the item with the given key.

If k is not in the map then it inserts it and returns a reference to that

const data_t& com::softwareag::connectivity::map_t::operator[] ( const data_t & k ) const

inline

Return a reference to the item with the given key.

If k is not in the map then throws std::runtime_error

void com::softwareag::connectivity::map_t::setName ( const char * name )

inline

Set the optional name of this map.

nullptr to undefine

size_t com::softwareag::connectivity::map_t::size ( ) const

inline

Returns the number of key/value pairs in the map.

void com::softwareag::connectivity::map_t::swap ( map_t && other )

inline

Swap the contents of this map and other.

void com::softwareag::connectivity::map_t::swapName ( map_t && other )

inline

Swap the name of this map and other.
