Readonly$

$: { $modelId: string; items: { [k: string]: any } }

Data part of the model, which is observable and will be serialized in snapshots. Use it if one of the data properties matches one of the model properties/functions.

Readonly$modelType

$modelType: string

Model type name.

items

items: { [k: string]: any } = ...

Accessors

$modelId

  • get $modelId(): ModelIdPropertyType<TProps, ModelIdPropertyName>

  • Model internal id. Can be modified inside a model action. It will return undefined if there's no id prop set.

    Returns ModelIdPropertyType<TProps, ModelIdPropertyName>

  • set $modelId(newId: ModelIdPropertyType<TProps, ModelIdPropertyName>): void

  • Parameters

    Returns void

size

  • get size(): number

  • Returns number

    the number of elements in the Map.

Methods

[iterator]

  • "[iterator]"(): MapIterator<[string, V]>

  • Returns MapIterator<[string, V]>

clear

  • clear(): void

  • Returns void

delete

  • delete(key: string): boolean

  • Parameters

    • key: string

    Returns boolean

    true if an element in the Map existed and has been removed, or false if the element does not exist.

entries

  • entries(): MapIterator<[string, V]>

  • Returns an iterable of key, value pairs for every entry in the map.

    Returns MapIterator<[string, V]>

forEach

  • forEach(
        callbackfn: (value: V, key: string, map: Map<string, V>) => void,
        thisArg?: any,
    ): void

  • Executes a provided function once per each key/value pair in the Map, in insertion order.

    Parameters

    • callbackfn: (value: V, key: string, map: Map<string, V>) => void
    • OptionalthisArg: any

    Returns void

get

  • get(key: string): undefined | V

  • Returns a specified element from the Map object. If the value that is associated to the provided key is an object, then you will get a reference to that object and any change made to that object will effectively modify it inside the Map.

    Parameters

    • key: string

    Returns undefined | V

    Returns the element associated with the specified key. If no element is associated with the specified key, undefined is returned.

getRefId

  • getRefId(): undefined | string

  • Can be overridden to offer a reference id to be used in reference resolution. By default it will use the idProp if available or return undefined otherwise.

    Returns undefined | string

has

  • has(key: string): boolean

  • Parameters

    • key: string

    Returns boolean

    boolean indicating whether an element with the specified key exists or not.

keys

  • keys(): MapIterator<string>

  • Returns an iterable of keys in the map

    Returns MapIterator<string>

set

  • set(key: string, value: V): this

  • Adds a new element with a specified key and value to the Map. If an element with the same key already exists, the element will be updated.

    Parameters

    • key: string
    • value: V

    Returns this

toString

  • toString(options?: { withData?: boolean }): string

  • Parameters

    • Optionaloptions: { withData?: boolean }

    Returns string

typeCheck

  • typeCheck(): null | TypeCheckError

  • Performs a type check over the model instance. For this to work a data type has to be declared as part of the model properties.

    Returns null | TypeCheckError

    A TypeCheckError or null if there is no error.

values

  • values(): MapIterator<V>

  • Returns an iterable of values in the map

    Returns MapIterator<V>
