Now you can simplify:
StringParameter valueS = resource.getParameter("bagId", "paramId");
String value = valueS.getValue();
to:
String value = resource.getParameter("bagId", "paramId").getValue();
Casting is done implicitly, thus this can lead to runtime exceptions
when the parameter is not of the relevant type, but otherwise it reduces
the code by one line.
Setting the value in this manor is not supported due to the
ListParameters requiring a type of List<T>.
These allow to get the date or state respectively from a
StrolchRootElement which supports such a field (Order and/or Activity)
and thus eliminates the need for casting
This is required because in certain instances it is important to lock
the object before retrieving it, otherwise if, for instance in
execution, we would need to fetch, lock and re-fetch to be sure we have
the latest object.
In moste of the Update*Commands this is not important as we perform a
list commit wins, where the client wants their version to be persisted.
Later a optimistic locking can be performed in that the given version
must be the latest, otherwise an exception would be thrown
Using the DurationExecution:
<Activity Id="produceBicycle" Name="Activity" Type="ToStock"
TimeOrdering="Series">
<ParameterBag Name="objectives" Id="Objectives" Type="Objectives">
<Parameter Name="Duration" Id="duration" Value="PT0.01S"
Type="Duration" />
</ParameterBag>
<Action Id="produce" Name="Produce" ResourceId="bicycle"
ResourceType="Product" Type="Produce" />
</Activity>
IActivityElement now has a new method .findParameter() to search up the
activity hierarchy to find the element
We have three major blocks:
- In Execution Warning:
- STOPPED
- WARNING
- ERROR
- in execution:
- above including EXECUTION and EXECUTED
- in planning:
- PLANNING and PLANNED
- CREATED
- CLOSED
EXECUTION is used if any action is EXECUTED and a prior state exists
PLANNING is used if any action is PLANNED and PLANNING or CREATED
state exists
CLOSED is only used if everything is CLOSED, otherwise one of the
previous states is used
