Workflow Manual / Version 2301
Table Of ContentsExpressions come in two variants:
generic expressions and
Boolean expressions.
A generic expression must evaluate to a java.lang.Comparable result and can be
used for example in a <Less> or <Greater> expression. A
Boolean expression must evaluate to a Boolean result value and can be used for
example in a <Condition> task.
Expressions can be used for many purposes in the workflow:
Guards for automated and user tasks
Preconditions and postconditions (assertions) in automated and user task
Validators for variable assignments in client views
Conditions for branching tasks
Guards for actions
