+/**
+ * This class is used to test Ndb's ability to handle
+ * node- and system-restarts.
+ * For example:
+ * Node restart: Restart one node in the cluster.
+ * System restart: Restart all nodes in the cluster.
+ * Node crash: Crash one node in the middle of execution and bring it up again.
+ * Multiple node crash: Crash multiple nodes with a few seconds or milliseconds delay between.
+ * Initial node restart: Restart one node in the cluster without a filesystem on disk.
+ *
+ * Each restart type is represented by a NdbRestart class and a collection of these are stored
+ * in the NdbRestarts class.
+ *
+ * This class may be used from other programs to execute a particular restart.
