The valid state transitions specified for the DomainDownload Program are specified inTable A.1.Each of the transitions defines a start state and end state for the transition and is identified by a unique number. Five of the transitions are from the base ProgramStateMachineTypeand retain the transition identifier numbers specified for Programs. The additional transitions relate the base Program states with the subordinate states defined for the DomainDownload. These states have been assigned unique transition identifier numbers that distinguish them from the base Programtransition identifiers. In cases where transitions occur between substates and the Program’sbase states, two transitions are specified. One transition identifies the base state change and a second substate change. For example, ReadyToRunning and ToOpening occur at the same time.
Table A.1 also specifies the defined states, causes for the transitions, and the effects of each transition. Program Control Methodsare used by the Clientto “run” the DomainDownload. The Methodscause or trigger the specified transitions. The transition effects are the specified EventTypeswhich notify the Clientof Programactivity.
