The defaultCallable class is a stubbed-out implementation of the PCHcallable
interface with an empty definition for the processCustomMessage
method. When the application does not require the functionality afforded by
the callbacks specified in the PCHcallable interface, it can use an instance
of this class as the value for the heartbeatObject
parameter
of the constructor of the Listener object. The
heartbeatObject
provides the Listener with the ability
to handle health status requests or Custom Messages received from connected
Managers. When no value is specified for the heartbeatObject
,
then an instance of the defaultCallable class is automatically created.
For more information about implementing this class, see Supporting Communication from Managers.
