Properties

readonly
isEmpty: boolean

Returns true if the collection is empty.

readonly
size: number

Returns the number of values in the collection.

readonly
sizeDistinct: number

Returns the number of distinct values in the collection.

readonly
countMap: WithElem<Tp, T>["countMap"]

Returns the Map representation of this collection.

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 collection as a .NonEmpty type

stream(): Stream<T>

Returns a Stream containing all values of this collection.

streamDistinct(): Stream<T>

Returns a Stream containing all distinct values of this collection.

remove<U = T>(value: RelatedTo<T, U>, amount?: number | "ALL"): WithElem<Tp, T>["normal"]

Returns the collection where the given amount (default: 'ALL') of the given value are removed.

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

Returns the collection where every single value from given values StreamSource is removed.

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

Returns the collection where for every value from given values StreamSource, all values in the collection are removed.

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

Returns true if the given value exists in the collection.

count<U = T>(value: RelatedTo<T, U>): number

Returns the amount of occurrances of the given value in the collection.

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.

filterEntries(pred: (entry: readonly [T, number], index: number) => boolean): WithElem<Tp, T>["normal"]

Returns the collection containing only those values for which the given pred function returns true.

toArray(): T[]

Returns an array containing all values in this collection.

toString(): string

Returns a string representation of this collection.

toJSON(): ToJSON<(readonly [T, number])[]>
