Trait: DataStorage

Properties

Name	Trait	Description
value	any	Holds the current value in the storage. Readonly.

Methods

constructor() => DataStorage

Instantiates a new data storage.

fill(value: any) => void

fills the data storage with the given value.

when(callback: (value: any) => void) => void

Registers a callback for when ever a new value is filled into the data storage. This also fires if there is already a value inside the storage.

whenNext(callback: (value: any) => void) => void

Same as when() but only fires when the data storage is filled the next time. The callback is not invoked for the current value.

once(callback: (value: any) => void) => void

Registers a callback which is invoked once the data storage has been filled. If the storage is already filled, it is invoked immediately.

Specialties

Every method has two properties. then() and catch(). This means they can always be passed into something that expects a promise. While catch()'s callback never will be called, the then() callbacks will be registered just like they would have been in the actual function.
