Description

Observable implementation of ExpandedKeySet that keeps track of mutation of KeySet. Since KeySet is immutable, all mutation methods return a new KeySet, and therefore applications must update the associated attribute with the new KeySet. The ObservableExpandedKeySet provides a convenient way for applications to mutate the KeySet directly without the need to update the associated attribute.
Deprecated:
Since Description
7.0.0 Use ObservableKeySet instead.

Constructor

new ObservableExpandedKeySet(initialValue)

Create an observable version of a KeySet.
Parameters:
Name Type Argument Description
initialValue ExpandedKeySet.<K> | ExpandAllKeySet.<K> <optional>
