Detailed Description

template<typename ValueTy, typename AllocatorTy = MallocAllocator>
class wpi::StringMap< ValueTy, AllocatorTy >

StringMap - This is an unconventional map that is specialized for handling keys that are "strings", which are basically ranges of bytes.

This does some funky memory allocation and hashing things to make it extremely efficient, storing the string data after the value in the map.

template<typename ValueTy , typename AllocatorTy = MallocAllocator>

template<typename InputIt >

void wpi::StringMap< ValueTy, AllocatorTy >::insert	(	InputIt	First,
		InputIt	Last
	)

inline

Inserts elements from range [first, last).

If multiple elements in the range have keys that compare equivalent, it is unspecified which element is inserted .

◆ insert() [2/4]

template<typename ValueTy , typename AllocatorTy = MallocAllocator>

bool wpi::StringMap< ValueTy, AllocatorTy >::insert ( MapEntryTy * KeyValue )

inline

insert - Insert the specified key/value pair into the map.

If the key already exists in the map, return false and ignore the request, otherwise insert it and return true.

◆ insert() [3/4]

template<typename ValueTy , typename AllocatorTy = MallocAllocator>

void wpi::StringMap< ValueTy, AllocatorTy >::insert ( std::initializer_list< std::pair< std::string_view, ValueTy > > List )

inline

Inserts elements from initializer list ilist.

If multiple elements in the range have keys that compare equivalent, it is unspecified which element is inserted

template<typename ValueTy , typename AllocatorTy = MallocAllocator>

std::pair< iterator, bool > wpi::StringMap< ValueTy, AllocatorTy >::insert ( std::pair< std::string_view, ValueTy > KV )

inline

insert - Inserts the specified key/value pair into the map if the key isn't already in the map.

The bool component of the returned pair is true if and only if the insertion takes place, and the iterator component of the pair points to the element with key equivalent to the key of the pair.

◆ insert_or_assign()

template<typename ValueTy , typename AllocatorTy = MallocAllocator>

template<typename V >

std::pair< iterator, bool > wpi::StringMap< ValueTy, AllocatorTy >::insert_or_assign	(	std::string_view	Key,
		V &&	Val
	)

inline

Inserts an element or assigns to the current element if the key already exists.

The return type is the same as try_emplace.

inline

◆ operator==()

template<typename ValueTy , typename AllocatorTy = MallocAllocator>

bool wpi::StringMap< ValueTy, AllocatorTy >::operator== ( const StringMap< ValueTy, AllocatorTy > & RHS ) const

inline

equal - check whether both of the containers are equal.

◆ operator[]()

template<typename ValueTy , typename AllocatorTy = MallocAllocator>

ValueTy & wpi::StringMap< ValueTy, AllocatorTy >::operator[] ( std::string_view Key )

inline

Lookup the ValueTy for the Key, or create a default constructed value if the key is not in the map.

◆ remove()

template<typename ValueTy , typename AllocatorTy = MallocAllocator>

void wpi::StringMap< ValueTy, AllocatorTy >::remove ( MapEntryTy * KeyValue )

inline

remove - Remove the specified key/value pair from the map, but do not erase it.

This aborts if the key is not in the map.

◆ try_emplace()

template<typename ValueTy , typename AllocatorTy = MallocAllocator>

template<typename... ArgsTy>

std::pair< iterator, bool > wpi::StringMap< ValueTy, AllocatorTy >::try_emplace	(	std::string_view	Key,
		ArgsTy &&...	Args
	)

inline

Emplace a new element for the specified key into the map if the key isn't already in the map.

The bool component of the returned pair is true if and only if the insertion takes place, and the iterator component of the pair points to the element with key equivalent to the key of the pair.
