This item is read only and cannot be modified. Read Only
</>
ObservableMap.KeyAdded: Signal<TKey>

Fires when a key is added

KeyRemoved​

This item is read only and cannot be modified. Read Only
</>
ObservableMap.KeyRemoved: Signal<TKey>

Fires when a key is removed

KeyValueChanged​

This item is read only and cannot be modified. Read Only
</>
ObservableMap.KeyValueChanged: Signal<(
TKey,
TValue,
TValue
)>

Fires when a key value changes, including add and remove.

CountChanged​

</>
ObservableMap.CountChanged: RBXScriptSignal

Fires when the count changes.

Functions​

new​

</>
ObservableMap.new() → ObservableMap<TKey,TValue>

Returns whether the set is an observable map

ObserveValueForKey​

</>
ObservableMap.ObserveValueForKey(key: TKey) → Observable<TValue?>

Observes the value for the given key. Alias for ObservableMap.ObserveAtKey.

</>
ObservableMap:ObserveKeysBrio() → Observable<Brio<TKey>>

Observes all keys in the map

ObserveValuesBrio​

</>
ObservableMap:ObserveValuesBrio() → Observable<Brio<TKey>>

Observes all keys in the map

ObservePairsBrio​

</>
ObservableMap:ObservePairsBrio() → Observable<Brio<(
TKey,
TValue
)>>

Observes all keys in the map

Get​

</>
ObservableMap:Get(key: TKey) → TValue

Returns the value for the given key

ContainsKey​

</>
ObservableMap:ContainsKey(key: TKey) → boolean

Returns whether the map contains the key

GetCount​

</>
ObservableMap:GetCount() → number

Gets the count of items in the set

ObserveCount​

</>
ObservableMap:ObserveCount() → Observable<number>

Observes the count of the set

ObserveAtKeyBrio​

</>
ObservableMap:ObserveAtKeyBrio(key: TKey) → Observable<Brio<TValue>>

Observes the value for the given key.

ObserveAtKey​

</>
ObservableMap:ObserveAtKey(key: TKey) → Observable<TValue?>

Observes the value for the given key.

Set​

</>
ObservableMap:Set(
key: TKey,
value: TValue?
) → callback--

Call to remove the value if it was added

Adds the item to the set if it does not exists.

Remove​

</>
ObservableMap:Remove(key: TKey) → ()

Removes the item from the map if it exists.

GetValueList​

</>
ObservableMap:GetValueList() → {TValue}

Gets a list of all values.

GetKeyList​

</>
ObservableMap:GetKeyList() → {TKey}

Gets a list of all keys.

ObserveKeyList​

</>
ObservableMap:ObserveKeyList() → Observable<{TKey}>

Observes the list of all keys.

Destroy​

</>
ObservableMap:Destroy() → ()

Cleans up the ObservableMap and sets the metatable to nil.
