override
forEach(void action($K key, $V value)) → void
Applies action to each key/value pair of the map.
inherited
isA<T extends JObject?>(JObjType<T> type) → bool
Whether this object is of the given type ignoring the type parameters.
inherited
isInstanceOf(JClass jclass) → bool
Whether this object is of the type of the given jclass.
inherited
map<K2, V2>(MapEntry<K2, V2> transform($K key, $V value)) → Map<K2, V2>
Returns a new map where all entries of this map are transformed by the given convert function.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
putIfAbsent($K key, $V ifAbsent()) → $V
Look up the value of key, or add a new entry if it isn't there.
inherited
release() → void
Releases the underlying reference.
inherited
releasedBy(Arena arena) → void

inherited
remove(Object? key) → $V?
Removes key and its associated value, if present, from the map.
override
removeWhere(bool test($K key, $V value)) → void

Available on T, provided by the JObjectUseExtension extension

Applies callback on this object and then delete the underlying JNI reference, returning the result of callback.

Operators

operator ==(Object other) → bool
The equality operator.
inherited
operator [](Object? key) → $V?
