public class ConfigurationState

extends RootObject

This class encapsulates the state of a reconfiguration manager. A reconfiguration is usually the result of a detected or suspected fault in an object that, through the reconfiguration, is excluded from the normal flow of control. Reconfiguration information should therefore be preserved across software and hardware resets in order to allow safe autonomous re-initialization of the AOCS software.

Configuration information is stored in an object of type ConfigurationState. This object encapsulates the configuration of a reconfiguration group by storing the following information: the configurations that have been marked unhealthy; and the current configuration. Individual configuration managers may add more specific information.

Storage of configuration information is done using the memento design pattern. Since the exact format of the configuration state data cannot be specified in advance, the internal structure of the ConfigurationState type remains correspondingly open. Essentially, configuration state object reserve a fixed amount of memory that reconfiguration managers can use to store class-specific information. In the present implementation, this "memory pad" area consists of a single integer.
