Inheritance diagram for MapInterface< K, V >:

[legend]

Detailed Description

template<typename K, typename V>
class maxon::MapInterface< K, V >

MapInterface is an interface which provides the usual map functions as virtual methods. Each standard map of the MAXON API can be represented as such an interface, so this allows to write non-template functions which nevertheless are able to deal with any kind of map.

If the function won't modify both the structure and values of the map, you should use a const MapInterface with const values:

void Func(const MapInterface<Int, const String>& map);
 
HashMap<Int, String> myMap;
Func(myMap); // OK
ArrayMap<Int, String> myMap2;
Func(myMap2); // OK

The access to the set happens via virtual methods, so there is an inevitable performance penalty, but this will be negligible for most use cases.

For a map which shall be modified, use WritableMapInterface as type of the function parameter instead.

Template Parameters

K	Type of keys of the map.
V	Type of values of the map.

MAXON_METHOD ResultRef<V> InsertKey	(	const K &	key,
		Bool &	created = `BoolLValue()`
	)

Finds the value associated with the given key, or creates a corresponding entry if it doesn't exist yet. The value of a new entry has to be initialized afterwards (but its default constructor has already been invoked).

Finds the value associated with the given key, or creates a corresponding entry if it doesn't exist yet. The value of a new entry has to be initialized afterwards (but its default constructor has already been invoked).

Parameters

		VALUE &&	value,
		Bool &	created = `BoolLValue()`
	)

Associates the given value with the given key. This adds a new entry for key if necessary, and then sets its value to the given value, whether the entry existed before or not.

Parameters

[in]	key	Key which shall map to the value.
[in]	value	Value to which the key shall map.
[out]	created	This will be set to true if a new entry has been created, otherwise it will be set to false.

		Bool &	created = `BoolLValue()`
	)

Associates the given value with the given key. This adds a new entry for key if necessary, and then sets its value to the given value, whether the entry existed before or not.

Parameters

[in]	key	Key of the entry to find or create. If a new entry is created, its key will be constructed by move-semantics if possible.
[in]	value	Value to which the key shall map.
[out]	created	This will be set to true if a new entry has been created, otherwise it will be set to false.

Returns: Pointer to value for the given key, or nullptr if an entry didn't exist and allocation of a new entry failed.

◆ FindValue() [1/2]

MAXON_METHOD V* FindValue ( const K & key )

Parameters

[in] key Key to search for.

Returns: Pointer to value for the given key, or nullptr if no entry exists for the key.

◆ Erase() [1/2]

MAXON_METHOD Result<Bool> Erase ( const K & key )

Removes an entry with the given key from this map (if possible).

Parameters

[in] key Key of the map entry to be be removed.

Returns: True if an entry was found and removed for key, otherwise false or an error if a memory allocation failed.

◆ Erase() [2/2]

MAXON_METHOD Iterator Erase ( const Iterator & iterator )

Removes the element at iterator from this set. The returned iterator will point to the element behind the last removed element.

Parameters

[in] iterator Iterator pointing to the element to be removed.

Returns: Iterator pointing to the element behind the removed element.

◆ Reset()

MAXON_METHOD void Reset ( )

Deletes all elements (calls destructors and frees memory).

◆ Flush()

MAXON_METHOD void Flush ( )

Deletes all elements, but doesn't free memory (calls destructors though).

◆ CopyFrom()

Sets this map to a copy of the given other map.

Parameters

[in] other Source map.

Returns: Success of operation.

◆ Clone()

MAXON_METHOD Result<MapInterface*> Clone ( Bool copyContent = true ) const

Returns: Pointer to the new map object, nullptr if allocation or copying failed.

◆ GetKeyDataType()

MAXON_METHOD const DataType& GetKeyDataType ( ) const

Parameters

[in] formatStatement Nullptr or additional formatting instruction. Currently no additional formatting instructions are supported.

MAXON_METHOD Int GetMemorySize ( ) const

Calculates the memory usage for this map.

Returns: Memory size in bytes.

◆ HasType()

MAXON_FUNCTION Bool HasType ( ) const

◆ AssertType()

MAXON_FUNCTION void AssertType ( ) const

Issues a failed DebugAssert if the DataTypes of this map doesn't match KT/VT. For Generic, no check happens.

Template Parameters

KT	Type of keys to check.
VT	Type of values to check.

◆ AssertCast() [1/2]

MapInterface<KT, VT>& AssertCast ( )

Casts this map to a map with keys of type KT and values of type VT. If one of they types doesn't match the actual data type of this map, a failed DebugAssert is issued. This function only makes sense when the original map uses Generic for at least one of its types.

Template Parameters

KT	Assumed key type of the map.
VT	Assumed value type of the map.

Returns: This map, cast to a MapInterface<KT, VT>.

◆ AssertCast() [2/2]

const MapInterface<KT, VT>& AssertCast ( ) const

Casts this map to a map with keys of type KT and values of type VT. If one of they types doesn't match the actual data type of this map, a failed DebugAssert is issued. This function only makes sense when the original map uses Generic for at least one of its types.

Template Parameters

KT	Assumed key type of the map.
VT	Assumed value type of the map.

Returns: This map, cast to a MapInterface<KT, VT>.
