Description

Sub-Service of the InteractionDirector: Hold and maintain InteractionState.

Typically, each distinct gesture or elaborate interaction pattern has a dedicated InteractionState subclass to maintain the state of ongoing gestures within the UI. Client code attaches and accesses this state through the CmdContext front-end. The InteractionDirector exposes a singleton instance of the GestureState manager through the lib::Depend access framework (Dependency-Injection).
