_handles: Handles<unknown, ResourceHandle>

`Protected`_originalMap

_originalMap: ObservableMap<string, V> | Map<string, V>

Accessors

size

get size(): number
The number of elements.

Returns number
Inherited from ObservableMap.size

Methods

[iterator]

[iterator](): MapIterator<[string, V]>
Returns the [key, value] pairs for each element in the map in insertion order.

Returns MapIterator<[string, V]>
Overrides ObservableMap.[iterator]

clear

clear(): void
Removes all elements.

Returns void
Inherited from ObservableMap.clear

delete

delete(key): boolean
Removes the specified element.
Parameters
- key: string
  The element's key.
Returns boolean
True if an element was deleted, otherwise false.

Overrides ObservableMap.delete

destroy

destroy(): void
Returns void
Inherited from ObservableMap.destroy

entries

entries(): MapIterator<[string, V]>
Returns the [key, value] pairs for each element in the map in insertion order.

Returns MapIterator<[string, V]>
Overrides ObservableMap.entries

forEach

forEach(callbackfn, thisArg?): void
Executes a provided function once per each key/value pair in the map.
Parameters
- callbackfn: ((value: V, key: string, map: Map<string, V>) => void)
  Function to execute for each element.
  - - (value, key, map): void
    - Parameters
      value: V
      key: string
      map: Map<string, V>
      Returns void
- OptionalthisArg: unknown
  Value to use as this when executing callback.
Returns void
Inherited from ObservableMap.forEach

get

get(key): 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 V
Returns the element associated with the specified key. If no element is associated with the specified key, undefined is returned.

Overrides ObservableMap.get

has

has(key): boolean
Indicates whether or not an element with the specified key exists.
Parameters
- key: string
  The key to test for.
Returns boolean
Overrides ObservableMap.has

keys

keys(): MapIterator<string>
Returns the keys for each element in the map in insertion order.

Returns MapIterator<string>
Overrides ObservableMap.keys

set

set(key, value?): 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
- Optionalvalue: V
Returns this
Overrides ObservableMap.set

toJSON

toJSON(): unknown
Returns a serializable representation of the map.

Returns unknown
Inherited from ObservableMap.toJSON

values

values(): MapIterator<V>
Returns the values for each element in the map in insertion order.

Returns MapIterator<V>
Inherited from ObservableMap.values
