A state is a single stage in a + * policy. A state has a single input event, its trigger. A state can output many events, but can + * only output one event on a single execution. After it executes, a state can pass control to + * another state or can simply emit its event to an external system. In the case where a state + * passes control to another state, the output event of the state becomes the input event of the + * next state. The outputs of a state {@link AxStateOutput} are held as a map in the state. Each + * state output contains the outgoing event of the state and optionally the next state to pass + * control to. + * <p> + * A state uses tasks {@link AxTask} to execute its logic. A state holds its tasks in a map and must + * have at least one task. A state uses Task Selection Logic {@link AxTaskSelectionLogic} to select + * which task should be executed in a given execution cycle. Optional Task Selection Logic can use + * fields on the incoming event and information from the context albums available on the state to + * decide what task to execute in a given context. The default task of a state is the task that is + * executed when task Selection Logic is not specified. In cases where only a single task is + * specified on a state, the default task must be that task and the state always executes that task. + * <p> + * What happens when a state completes its execution cycle depends on the task that is selected for + * execution by the state. Therefore, the action to be performed a state on execution of each task + * must be defined in the state as a {@link AxStateTaskReference} instance for each task defined in + * the state. The {@link AxStateTaskReference} instance defines the action to be performed as either + * a {@link AxStateTaskOutputType} of {@link AxStateTaskOutputType#DIRECT} or + * {@link AxStateTaskOutputType#LOGIC} and contains an {@link AxReferenceKey} reference to the + * instance that will complete the state output. + * <p> + * In the case of direct output, the {@link AxReferenceKey} reference in the + * {@link AxStateTaskReference} instance is a reference to an {@link AxStateOutput} instance. The + * state output defines the event to be emitted by the state and the next state to pass control to + * if any. All fields of the executed task are marshaled onto the outgoing event automatically by + * Apex. + * <p> + * In the case of logic output, the {@link AxReferenceKey} reference in the + * {@link AxStateTaskReference} instance is a reference to State Finalizer Logic in an + * {@link AxStateFinalizerLogic} instance, which selects the {@link AxStateOutput} that the state + * will use. The state finalizer logic uses fields emitted by the executed task and information from + * the context albums available on the state to decide what {@link AxStateOutput} to select in a + * given context. The state output defines the event to be emitted by the state and the next state + * to pass control to if any. The State Finalizer Logic instances for the state are held in a map in + * the state. State Finalizer Logic must marshal the fields of the output event in whatever manner + * it wishes; Apex does not automatically transfer the output fields from the task directly to the + * output event. + * <p> + * The Task Selection Logic instance or State Finalizer Logic instances in a state may use + * information in context albums to arrive at their task or state output selections. The context + * albums that the state uses and that should be made available to the state by Apex policy + * distribution are held as a set of references to context albums in the state. + * <p> + * During validation of a state, the validation checks listed below are executed: + * <ol> + * <li>The policy key must not be a null key and must be valid, see validation in + * {@link AxReferenceKey} + * <li>The trigger event key must not be a null key and must be valid, see validation in + * {@link AxArtifactKey} + * <li>At least one state output must be defined + * <li>Each state output in a state must have that state as its parent + * <li>Each state output must be valid, see validation in {@link AxStateOutput} + * <li>The next state defined in a state output must be unique in a state + * <li>The default task key must not be a null key and must be valid, see validation in + * {@link AxArtifactKey} + * <li>The default task must appear in the task map of the state + * <li>At least one task must be defined on the state + * <li>Each task key on the task map for the state must not be a null key and must be valid, see + * validation in {@link AxArtifactKey} + * <li>All state task references for each task in the state must exist and must be valid, see + * validation in {@link AxStateTaskReference} + * <li>Each state task reference in a state must have that state as its parent + * <li>For direct state outputs from tasks, the state output must be defined on the state + * <li>For logic state outputs from tasks, the State Finalizer Logic must be defined on the state + * <li>An observation is issued for each state output defined on the state that is not used as a + * direct output on a task + * <li>An observation is issued for each state finalizer logic instance defined on the state that is + * not used as an output on a task + * <li>Each context album key on the context album set for the state must not be a null key and must + * be valid, see validation in {@link AxArtifactKey} + * <li>Task Selection logic in a state must have that state as its parent + * <li>Task Selection logic in a state must be valid, see validation in {@link AxTaskSelectionLogic} + * <li>Each State Finalizer logic instance in a state must have that state as its parent + * <li>Each State Finalizer logic instance in a state must be valid, see validation in + * {@link AxStateFinalizerLogic} + * </ol> + */ + +@Entity +@Table(name = "AxState") + +@XmlAccessorType(XmlAccessType.FIELD) +@XmlRootElement(name = "apexState", namespace = "http://www.onap.org/policy/apex-pdp") +@XmlType(name = "AxState", namespace = "http://www.onap.org/policy/apex-pdp", + propOrder = {"key", "trigger", "stateOutputs", "contextAlbumReferenceSet", "taskSelectionLogic", + "stateFinalizerLogicMap", "defaultTask", "taskReferenceMap"}) + +public class AxState extends AxConcept { + private static final String DOES_NOT_EQUAL_STATE_KEY = " does not equal state key";
