It also uses the standard ``Java`` time utilities - to check if the current time is between ``00:00:00 GMT`` - and ``11:30:00 GMT``.

The 'Policy Trigger Event' is the input - event for the policy as a whole. This event is then - passed to the first state in the chain of states in the - policy, therefore the 'Policy Trigger Event' will be the - input event for the first state. Each policy can only - have one 'First State'. For our ``MyFirstPolicy`` policy, - select ``BoozeAuthDecide`` as the 'First State'. This - will automatically select ``SALE_INPUT`` as the 'Policy - Trigger Event' for our policy. - - .. container:: imageblock - - .. container:: content - - |Create a state| - - .. container:: title - - Figure 15.

This is how states are - chained together to form a (`Directed Acyclic Graph - (DAG) <https://en.wikipedia.org/wiki/Directed_acyclic_graph>`__ ) - of states. The final state(s) of a policy are those that do - not select any 'next' state. Since a 'State' can only - accept a single type of event, the type of the event emitted - by a previous 'State' must be match the incoming event type - of the next 'State'. This is also how the last state(s) in - a policy can emit events of different types. The 'State - Output Mapping' is also responsible for taking the - fields that are output by the task executed in the state and - populating the state’s output event before it is emitted. - - .. container:: paragraph - - Each 'Task' referenced in 'State' must have a defined - 'Output Mapping' to take the output of the task, select an - 'Outgoing Event' type for the state, populate the state’s - outgoing event, and then select the next state to be - executed (if any). - - .. container:: paragraph - - There are 2 basic types of output mappings: - - .. container:: olist arabic - - #. **Direct Output Mappings** have a single value for - 'Next State' and a single value for 'State Output - Event'. The outgoing event for the state is - automatically created, any outgoing event parameters - that were present in the incoming event are copied - into the outgoing event, then any task output fields - that have the same name and type as parameters in the - outgoing event are automatically copied into - the outgoing event. - - #. **Logic-based State Output Mappings / Finalizers** - have some logic defined that dynamically selects - and creates the 'State Outgoing Event', manages - the population of the outgoing event parameters - (perhaps changing or adding to the outputs from the - task), and then dynamically selects the next state to - be executed (if any). - - .. container:: paragraph - - Each task reference must also have an associated 'Output - State Mapping' so we need an 'Output State Mapping' for - the ``BoozeAuthDecide`` state to use when the - ``MorningBoozeCheck`` task is executed. The simplest type - of output mapping is a 'Direct Output Mapping'. - - .. container:: paragraph - - Create a new 'Direct Output Mapping' for the state called - ``MorningBoozeCheck_Output_Direct`` using the 'Add New - Direct State Output Mapping' button. Select ``SALE_AUTH`` - as the output event and select ``None`` for the next - state value. We can then select this output mapping for - use when the the ``MorningBoozeCheck`` task is executed. - Since there is only state, and only one task for that - state, this output mapping ensures that the - ``BoozeAuthDecide`` state is the only state executed and - the state (and the policy) can only emit events of type - ``SALE_AUTH``. (You may remember that the output fields - for the ``MorningBoozeCheck`` task have the exact same - names and reuse the item schemas that we used for the - parameters in ``SALE_AUTH`` event. The - ``MorningBoozeCheck_Output_Direct`` direct output mapping - can now automatically copy the values from the - ``MorningBoozeCheck`` task directly into outgoing - ``SALE_AUTH`` events.) - - .. container:: imageblock - - .. container:: content - - |Add a Task and Output Mapping| - - .. container:: title - - Figure 16.

Note, all tests - from Step 1 will still work perfectly since none of those - events originate from a branch with ``branch_ID`` between - ``1000`` and ``2000``. The 'Task Selection Logic' will - therefore pick the ``MorningBoozeCheck`` task as - expected, and will therefore give the same results. - - .. table:: Table 14.
