Detailed Description

template<typename KeyType, typename MappedType, size_t N>
class Scine::Molassembler::Temple::DynamicMap< KeyType, MappedType, N >

A constexpr associative container with reasonably fast key-based lookup.

Requires that MappedType is default-constructible

Template Parameters
KeyTypeType of the key in the map
MappedTypeValue type of the map
NMaximum number of elements in the map

template<typename KeyType , typename MappedType , size_t N>
constexpr const MappedType& Scine::Molassembler::Temple::DynamicMap< KeyType, MappedType, N >::at ( const KeyType &  key) const
inline

Value lookup.

Complexity \(\Theta(N \log N)\)

template<typename KeyType , typename MappedType , size_t N>
constexpr void Scine::Molassembler::Temple::DynamicMap< KeyType, MappedType, N >::clear ( )
inline

Inserts an element into the map.

Complexity \(\Theta(N \log N)\)

template<typename KeyType , typename MappedType , size_t N>
constexpr void Scine::Molassembler::Temple::DynamicMap< KeyType, MappedType, N >::insert ( KeyType  key,
MappedType  item 
)
inline

Inserts an element into the map.

Complexity \(\Theta(N \log N)\)

template<typename KeyType , typename MappedType , size_t N>
constexpr void Scine::Molassembler::Temple::DynamicMap< KeyType, MappedType, N >::insertOrUpdate ( KeyType  key,
MappedType  item 
)
inline

Inserts a key-value pair into the map or updates the mapped value if the key exists.

Complexity \(\Theta(N \log N)\)

template<typename KeyType , typename MappedType , size_t N>
constexpr unsigned Scine::Molassembler::Temple::DynamicMap< KeyType, MappedType, N >::size ( ) const
inline

Number of items in the map.

Complexity \(\Theta(1)\)
