Constructors

IMap()

Creates an empty IMap.

factory

IMap.fromMap(Map<K, V> other)

Creates an IMap with the same keys and values as other.

factory

IMap.fromRawPointer(Pointer<COMObject> ptr, {required String iterableIid, V creator(Pointer<COMObject>)?, K enumKeyCreator(int)?, V enumCreator(int)?})

Creates an instance of IMap using the given ptr and iterableIid.

Properties

ptr ↔ Pointer<COMObject>

getter/setter pair, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

size → int

Gets the number of items in the map.

no setter

Methods

addRef() → int

Increments the reference count for an interface pointer to a COM object.

inherited

clear() → void

Removes all items from the map.

first() → IIterator<IKeyValuePair<K, V>>

Returns an iterator for the items in the collection.

override

getIids(Pointer<Uint32> iidCount, Pointer<Pointer<GUID>> iids) → int

inherited

getView() → Map<K, V>

Returns an immutable view of the map.

hasKey(K value) → bool

Determines whether the map contains the specified key.

insert(K key, V value) → bool

Inserts or replaces an item in the map.

lookup(K key) → V

Returns the item at the specified key in the map.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

queryInterface(Pointer<GUID> riid, Pointer<Pointer<NativeType>> ppvObject) → int

Queries a COM object for a pointer to one of its interface; identifying the interface by a reference to its interface identifier (IID).

inherited

release() → int

Decrements the reference count for an interface on a COM object.

inherited

remove(K key) → void

Removes an item from the map.

toInterface(String iid) → Pointer<COMObject>

Cast an existing COM object to a specified interface.

inherited

toMap() → Map<K, V>

Creates an unmodifiable Map from the current IMap instance.

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool
