alib::containers::TPairDescriptor< TKey, TMapped > Struct Template Reference

Description:

template<typename TKey, typename TMapped>
struct alib::containers::TPairDescriptor< TKey, TMapped >

Implements template type TValueDescriptor, which is, for example, offered by types HashTable and LRUCacheTable.

Specifically, this implementation is used when the custom type to be stored with a container should be associated to a TKkey-type, which is not included in the stored type itself. Consequently, to associate custom type TMapped with the key, the StoredType results in std::pair<TKey,TMapped.

Type definitions HashMap and LRUCacheMap establish a shortcut to their corresponding base type, which incorporates this helper.

Template Parameters

TKey	The key type.
TMapped	The type of the mapped objects.

Type Definition Details:

KeyType

template<typename TKey, typename TMapped>

using alib::containers::TPairDescriptor< TKey, TMapped >::KeyType = TKey

The key type. (Exposes template parameter TKey).
Container types typically publish an alias to this type. For example, see KeyType, or see KeyType.

Definition at line 35 of file valuedescriptor.inl.

MappedType

template<typename TKey, typename TMapped>

using alib::containers::TPairDescriptor< TKey, TMapped >::MappedType = TMapped

The type associated to a key. (Exposes template parameter TMapped). The type of the mapped portion of the data.
Container types typically publish an alias to this type. For example, see MappedType, or see MappedType.

Definition at line 42 of file valuedescriptor.inl.

StoredType

template<typename TKey, typename TMapped>

using alib::containers::TPairDescriptor< TKey, TMapped >::StoredType = std::pair<TKey, TMapped>

The type stored in the container.
Container types typically publish an alias to this type. For example, see StoredType, or see StoredType.

Method Details:

Key()

template<typename TKey, typename TMapped>

TKey & alib::containers::TPairDescriptor< TKey, TMapped >::Key ( std::pair< TKey, TMapped > & src ) const

inline

Returns the first element of the given std::pair.

Parameters

src	The value to extract from.

Returns

The key-portion of the given value.

Definition at line 47 of file valuedescriptor.inl.

Mapped()

template<typename TKey, typename TMapped>

TMapped & alib::containers::TPairDescriptor< TKey, TMapped >::Mapped ( std::pair< TKey, TMapped > & src ) const

inline

Returns the second element of the given std::pair.

Parameters

src	The value to extract from.

Returns

The mapped-portion of the given value.
