Detailed Description

template<typename K, typename V, V v>
class lemon::ConstMap< K, Const< V, v > >

This readable map assigns a specified value to each key.

In other aspects it is equivalent to NullMap. So it conforms to the ReadWriteMap concept, but it absorbs the data written to it.

The simplest way of using this map is through the constMap() function.

Public Types
typedef K	Key

typedef V	Value

Public Types inherited from MapBase< K, V >
typedef K	Key
	The key type of the map.
typedef V	Value
	The value type of the map. (The type of objects associated with the keys).

Public Member Functions
	ConstMap ()
	Constructor.
Value	operator[] (const Key &) const
	Gives back the specified value.
void	set (const Key &, const Value &)
	Absorbs the value.
void	setAll (const Value &v)
	Sets the value that is assigned to each key.

Related Symbols
(Note that these are not member symbols.)
ConstMap< K, V >	constMap (const V &v)
	Returns a `ConstMap` class.
ConstMap< K, Const< V, v > >	constMap ()
	Returns a `ConstMap` class with inlined constant value.

◆ constMap() [1/2]

ConstMap< K, V > constMap ( const V & v )

This function just returns a ConstMap class.

ConstMap< K, Const< V, v > > constMap ( )

This function just returns a ConstMap class with inlined constant value.
