Working with Constraints

Constraint definitions let you veto the submission of a Process Definition or Chain Definition if it contains Parameters values that violate certain rules. Constraints are based on Constraint classes, which must be defined in a library.

To create a Constraint definition, navigate to Definitions > Constraints and click .

Tabs and Fields

The following table illustrates the fields of each tab of Constraint Definition editor dialogs.

Attaching a Constraint Definition to a Process or Chain Definition

There is no way to attach a Constraint definition to a Process Definition or Chain Definition in the user interface. Instead, use a RedwoodScript Process Definition with a Source script like the following.

{
    ConstraintDefinition cd = jcsSession.getConstraintDefinitionByName("MyConstraintDefinition");
    JobDefinition jd = jcsSession.getJobDefinitionByName("MyProcessDefinition");
    jd.createJobDefinitionConstraint(cd);
    jcsSession.persist();
}
