Type Parameters

optional

Tp extends VariantSetBase.Types = VariantSetBase.Types

Properties

readonly

size: number

Returns the number of values in the collection.

readonly

isEmpty: boolean

Returns true if the collection is empty.

Methods

nonEmpty(): this is WithElem<Tp, T>["nonEmpty"]

Returns true if there is at least one entry in the collection, and instructs the compiler to treat the collection as a .NonEmpty type.

assumeNonEmpty(): WithElem<Tp, T>["nonEmpty"]

Returns the same collection typed as non-empty.

stream(): Stream<T>

Returns a Stream containing all elements of this collection.

has(value: RelatedTo<T, U>): boolean

Returns true if given value is in the collection.

remove(value: RelatedTo<T, U>): WithElem<Tp, T>["normal"]

Returns the collection with given value removed.

removeAll(values: StreamSource<RelatedTo<T, U>>): WithElem<Tp, T>["normal"]

Returns the collection with all values in the given values StreamSource removed.

forEach(f: (

value: T,

index: number,

halt: () => void,

) => void, state?: TraverseState): void

Performs given function f for each value of the collection, using given state as initial traversal state.

filter(pred: (

value: T,

index: number,

halt: () => void,

) => boolean): WithElem<Tp, T>["normal"]

Returns a collection containing only those entries that satisfy given pred predicate.

difference(other: StreamSource<RelatedTo<T, U>>): WithElem<Tp, T>["normal"]

Returns a collection where each value of given other StreamSource is removed from this collection.

intersect(other: StreamSource<RelatedTo<T, U>>): WithElem<Tp, T>["normal"]

Returns a collection containing values that are both in this collection, and in the given other StreamSource.

toArray(): T[]

Returns an array containing all values in this collection.

toString(): string

Returns a string representation of this collection.

toJSON(): ToJSON<T[]>

Returns a JSON representation of this collection.
