interface HashSetCreators

undocumented

Extends: RSetBase.Factory<Tp,UT>

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

createContext

Returns a new HashSet context instance based on the given options.

Definition

createContext<UT>(options?: {
    hasher?: Hasher<UT>;
    eq?: Eq<UT>;
    blockSizeBits?: number;
    listContext?: List.Context;
  }): HashSet.Context<UT>;

Type parameters

NameDescription
UTthe upper element type for which the context can create instances

Parameters

NameTypeDescription
options{
    hasher?: Hasher<UT>;
    eq?: Eq<UT>;
    blockSizeBits?: number;
    listContext?: List.Context;
  }
(optional) an object containing the following properties:<br/. - hasher - (optional) a Hasher instance used to hash the map keys
- eq - (optional) an Eq instance used to determine key equality
- blockSizeBits - (optional) determines the maximum block size as 2 to the power of blockSizeBits
- listContext - (optional) the context to use to create list instances (for collisions)

defaultContext

Returns the default context for HashSets.

Definition

defaultContext<UT>(): HashSet.Context<UT>;

Type parameters

NameDescription
UTthe upper element type for which the context can create instances

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

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
