Methods | |
clone | Source Codeshared actual SingletonMap<Key,Item> clone() A shallow copy of this collection, that is, a collection with identical elements which does not change if this collection changes. If this collection is immutable, it is acceptable to return a reference to this collection. If this collection is mutable, a newly instantiated collection must be returned. |
contains | Source Codeshared actual Boolean contains(Object entry) Returns For any instance element in c For most
However, it is possible to form a useful |
defines | Source Codeshared actual Boolean defines(Object key) Determines if there is a value defined for the given key. |
each | Source Codeshared actual void each(void step(Key->Item element)) Call the given function ( For example: words.each((word) { print(word.lowercased); print(word.uppercased); }); Has the same effect as the following for (word in words) { print(word.lowercased); print(word.uppercased); } For certain streams this method is highly efficient,
surpassing the performance of Refines Iterable.each |
equals | Source Codeshared actual Boolean equals(Object that) Determine if two values are equal. For any two non-null objects x == y Implementations should respect the constraints that:
Furthermore it is recommended that implementations
ensure that if A class which explicitly refines Note that an implementation of |
get | Source Codeshared actual Item? get(Object key) Returns the value defined for the given key, or For any instance c[key] |
iterator | Source Codeshared actual Iterator<Key->Item> iterator() An iterator for the elements belonging to this stream. If this is a nonempty stream with type Refines Iterable.iterator |
