Wrapper around a class that implementsMap that only exposesMapmembers.

A simple wrapper that delegates allMap members to the map provided in theconstructor.

Base for delegating map implementations likeUnmodifiableMapView.

Implemented types

• Map<K,V>

Implementers

• UnmodifiableMapView

Constructors

MapView(Map<K,V>map)

Creates a view which forwards operations tomap.

Methods

addAll(Map<K,V>other)→ void

Adds all key/value pairs ofother to this map.

override

addEntries(Iterable<MapEntry<K,V>>entries)→ void

Adds all key/value pairs ofnewEntries to this map.

override

cast<RK,RV>()→Map<RK,RV>

Provides a view of this map as havingRK keys andRV instances,if necessary.

override

clear()→ void

Removes all entries from the map.

override

containsKey(Object?key)→bool

Whether this map contains the givenkey.

override

containsValue(Object?value)→bool

Whether this map contains the givenvalue.

override

forEach(voidaction(Kkey,Vvalue))→ void

Appliesaction to each key/value pair of the map.

override

map<K2,V2>(MapEntry<K2,V2>transform(Kkey,Vvalue))→Map<K2,V2>

Returns a new map where all entries of this map are transformed bythe givenconvert function.

override

noSuchMethod(Invocationinvocation)→ dynamic

Invoked when a nonexistent method or property is accessed.

inherited

putIfAbsent(Kkey,VifAbsent())→ V

Look up the value ofkey, or add a new entry if it isn't there.

override

remove(Object?key)→ V?

Removeskey and its associated value, if present, from the map.

override

removeWhere(booltest(Kkey,Vvalue))→ void

Removes all entries of this map that satisfy the giventest.

override

toString()→String

A string representation of this object.

override

update(Kkey,Vupdate(Vvalue), {VifAbsent()?})→ V

override

Operators

operator ==(Objectother)→bool

inherited

operator [](Object?key)→ V?

The value for the givenkey, ornull ifkey is not in the map.

override

operator []=(Kkey,Vvalue)→ void

Associates thekey with the givenvalue.
