IviServiceConnectionManagerImpl

The IVI service connection managers.

An IVI service connection manager manages the connection of a service interface instance identified by the iviInstanceId and serviceId.

<Interface>Api class instances can observe the connection of type C. As long as connection is observed by an active LifecycleOwner owner, the IVI service host manager will try to establish the connection.

connection is set when the IVI service host manager provide the connection data D. The IVI service host managers provides D when the connection has been established by calling onServiceConnectionAvailable. C is created through IviServiceInterfaceRegistration.connectionFactory of the serviceInterfaceRegistration. C is parameterized by the properties class P and a properties observer interface PO.

The manager keeps a cache of the IVI service interface properties. This cache is updated after a new connection is available and when the IVI service's serviceReady property is set to true. The cache is also updated on any following property changes. The caches are live data properties as such clients can observe the property changes.

serviceAvailable is set to true after the property cache is updated and set to false when either the connection is lost or when the IVI service's serviceReady property is set to false.

On disconnect, the IVI service connection manager is responsible to set the mutableConnection property to null.
