SortedMap

Defined in: packages/db/src/SortedMap.ts:8

A Map implementation that keeps its entries sorted based on a comparator function

Type Parameters

TKey

TKey extends string | number

The type of keys in the map (must be string | number)

TValue

TValue

The type of values in the map

Constructors

Constructor

ts
new SortedMap<TKey, TValue>(comparator?): SortedMap<TKey, TValue>;

Defined in: packages/db/src/SortedMap.ts:21

Creates a new SortedMap instance

Parameters

comparator?

(a, b) => number

Optional function to compare values for sorting. If not provided, entries are sorted by key only.

Returns

SortedMap<TKey, TValue>

Accessors

size

Get Signature

ts
get size(): number;

Defined in: packages/db/src/SortedMap.ts:196

Gets the number of key-value pairs in the map

Returns

number

Methods

[iterator]()

ts
iterator: IterableIterator<[TKey, TValue]>;

Defined in: packages/db/src/SortedMap.ts:205

Default iterator that returns entries in sorted order

Returns

IterableIterator<[TKey, TValue]>

An iterator for the map's entries


clear()

ts
clear(): void;

delete()

ts
delete(key, deferOrder): boolean;

Defined in: packages/db/src/SortedMap.ts:153

Removes a key-value pair from the map

Parameters

key

TKey

The key to remove

deferOrder

boolean = false

Defer ordering until restoreOrder or the next ordered read

Returns

boolean

True if the key was found and removed, false otherwise


entries()

ts
entries(): IterableIterator<[TKey, TValue]>;

Defined in: packages/db/src/SortedMap.ts:217

forEach()

ts
forEach(callbackfn): void;

Defined in: packages/db/src/SortedMap.ts:250

has()

ts
has(key): boolean;

Defined in: packages/db/src/SortedMap.ts:179

Checks if a key exists in the map

Parameters

key
