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:

RollbackTransactionWorkflowAction

This action causes the transaction manager to rollback the current transaction.

de.uplanet.lucy.server.workflow.action.RollbackTransactionWorkflowAction

VelocityWorkflowAction

Velocity templates can be generated with this action.

de.uplanet.lucy.server.workflow.action.VelocityWorkflowAction

TouchSessionWorkflowAction

A timeout of the current session can be prevented with this action.

de.uplanet.lucy.server.workflow.action.TouchSessionWorkflowAction

DisableTriggerSubsequentWorkflowEventsWorkflowAction

The triggering of subsequent events can be deactivated with this action.

de.uplanet.lucy.server.workflow.action.DisableTriggerSubsequentWorkflowEventsWorkflowAction

EnableTriggerSubsequentWorkflowEventsWorkflowAction

The triggering of subsequent events can be activated with this action.

de.uplanet.lucy.server.workflow.action.EnableTriggerSubsequentWorkflowEventsWorkflowAction

JMSQueueMessageProducerWorkflowAction

JMS messages can be sent to a queue with this action.

de.uplanet.lucy.server.jms.workflow.action.JMSQueueMessageProducerWorkflowAction

JMSTopicMessageProducerWorkflowAction

JMS messages can be sent to a topic with this action.

de.uplanet.lucy.server.jms.workflow.action.JMSTopicMessageProducerWorkflowAction

UDPSendDatagramWorkflowAction

UDP datagrams can be sent with this action.

de.uplanet.lucy.server.workflow.action.UDPSendDatagramWorkflowAction

GroupTextFeedWorkflowAction

Messages can be created in Intrexx Share groups with this action.

de.uplanet.lucy.server.share.workflow.action.GroupTextFeedWorkflowAction

Conditions

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

ApplicationApiRequestWorkflowCondition

In processes, you can use this condition to distinguish application API requests from others.

It has three possible outputs, which are named "true", "false" and "always" by default. The names can be changed in the 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 applicable).

If there is no Application API Request, the False output is processed first and then the Always output (if applicable). More information about this is available 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 string parameters. The first parameter is the name of the permission, the second parameter (optional) defines the actions.
  More information about this is available 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 if the current user has the permission to create new 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 defined in the attribute "efferentTransitionOrder" separated by spaces. If, for example, "two one three" is entered there, the output "two" is passed through first, then the output "one" and finally the 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
