Java classes in process objects

Java classes can be defined for diverse process objects. These implement specific use cases within event sources, event handlers, conditions and actions. The selectable classes are described in the following. The links below provide additional information about Java classes in process objects:

Conditions

The following event classes can be defined when configuring generic conditions:

ApplicationApiRequestWorkflowCondition

You can use this condition to distinguish application API requests from others in processes.

It has three possible outputs, which are named "true", "false" and "always" by default. The names can be changed in dialog. At least one output must be defined. A maximum of three outputs may be defined in the condition.

If there is an Application API request, the True output is processed first and then the Always output (if available).

If there is no Application API request, the False output is processed first and then the Always output (if available). Further information can be found here: Intrexx Application API.

CheckPermissionWorkflowCondition

Checks a permission and selects the specified output defined for transitionGrant or transitionDeny based on the result.

Attributes:

• transitionGrant

• transitionDeny

• permissionClass
  The permission class does not need to implement the de.uplanet.lucy.security.permission.IIntrexxPermission class. It must derive from java.security.Permission and have one or two constructor parameters of type "String". The first parameter is the name of the permission, the second (optional) is the actions.
  Further information can be found here:
  https://help.intrexx.com/apidocs/jdk21/api/java.base/java/security/Permission.html
  https://docs.intrexx.com/intrexx/version/steady/api/workflow/jdk/de/uplanet/lucy/security/permission/IIntrexxPermission.html

• permissionActions
  The name of the specific permission to be checked must be defined here.

• permissionName
  The GUID of the object to which the request refers must be specified here.

Example:

            permissionClass: de.uplanet.lucy.security.permission.DatagroupPermission
        permissionActions: create
        permissionName: <DG-GUID>
        

This configuration checks whether the current user is authorized to create new data records in the <DG-GUID> data group.

Class:

            de.uplanet.lucy.server.workflow.condition.CheckPermissionWorkflowCondition
        

ListingWorkflowCondition

This condition can be used to specify a sequence for processing the outputs in the form of a list. ListingWorkflowCondition is always true. The names of the outputs must be stored in the "efferentTransitionOrder" attribute, separated by spaces. If, for example, "two one three" is entered there, output "two" is run through first, then output "one" and finally output "three".

Class:

            de.uplanet.lucy.server.workflow.condition.ListingWorkflowCondition
        

RandomWorkflowCondition

This condition is used to randomly select either the true or false output. The probability of this happening is controlled by the specified weights:

• 1:1 corresponds to p = q = 0.5

• 3:1 corresponds to p = 0.25 and q = 0.75, etc.

Class:

            de.uplanet.lucy.server.workflow.condition.RandomWorkflowCondition
        

From Intrexx version 12.0.0

TransactedAcquireLockWorkflowCondition

Sets a lock cluster-wide via the lock service and releases it again at the end of the transaction. The condition has two outputs: success and failure.

Class:

                de.uplanet.lucy.server.workflow.condition.TransactedAcquireLockWorkflowCondition
            

Event handlers
