The List context used create Lists to keep value insertion order.

Methods​

builder​

Returns an empty builder instance for this type of collection and context.

Definition​

builder<T extends UT>(): WithElem<Tp, T>['builder'];

Type parameters​

NameConstraintsDescription
TUT
example
HashSet.builder<number>()     // => HashSet.Builder<number>

Overrides​

Factory.builder

empty​

Returns the (singleton) empty instance of this type and context with given value type.

Definition​

empty<T extends UT>(): WithElem<Tp, T>['normal'];

Type parameters​

NameConstraintsDescription
TUT
example
HashSet.empty<number>()    // => HashSet<number>
HashSet.empty<string>()    // => HashSet<string>

Overrides​

Factory.empty

from​

Returns an immutable set of this collection type and context, containing the given values in source.

Definitions​

from<T extends UT>(...sources: ArrayNonEmpty<StreamSource.NonEmpty<T>>): WithElem<Tp, T>['nonEmpty'];
from<T extends UT>(...sources: ArrayNonEmpty<StreamSource<T>>): WithElem<Tp, T>['normal'];

Type parameters​

NameConstraintsDescription
TUT

Parameters​

NameTypeDescription
sourcesArrayNonEmpty<StreamSource.NonEmpty<T>>an array of StreamSource instances containing values
example
HashSet.from([1, 2, 3], [4, 5])   // => HashSet.NonEmpty<number>

Overrides​

Factory.from

isValidValue​

Returns true if given value could be a valid value in this Context.

Definition​

isValidValue(value: any): value is UT;

Parameters​

NameTypeDescription
valueanythe object to check
example
HashSet.defaultContext().isValidValue(1)   // => true

Overrides​

Context.isValidValue

of​

Returns an immutable set of this type and context, containing the given values.

Definition​

of<T extends UT>(...values: ArrayNonEmpty<T>): WithElem<Tp, T>['nonEmpty'];

Type parameters​

NameConstraintsDescription
TUT

Parameters​

NameTypeDescription
valuesArrayNonEmpty<T>a non-empty array of values
example
HashSet.of(1, 2, 3).toArray()   // => [1, 2, 3]

Overrides​

Factory.of

reducer​

Returns a Reducer that appends received items to an RSet and returns the RSet as a result. When a source is given, the reducer will first create an RSet from the source, and then append elements to it.

Definition​

reducer<T extends UT>(source?: StreamSource<T>): Reducer<T, WithElem<Tp, T>['normal']>;

Type parameters​

NameConstraintsDescription
TUT

Parameters​

NameTypeDescription
sourceStreamSource<T>(optional) an initial source of elements to append to
example
const someList = SortedSet.of(1, 2, 3);
const result = Stream.range({ start: 20, amount: 5 }).reduce(SortedSet.reducer(someList))
result.toArray()   // => [1, 2, 3, 20, 21, 22, 23, 24]
note

uses an RSet builder under the hood. If the given source is a RSet in the same context, it will directly call .toBuilder().

Overrides​

Factory.reducer
