Class Condition

java.lang.Object

com.orchestranetworks.workflow.Condition

public abstract class Condition
extends Object

Condition node; its purpose is to evaluate which fork the process must take.

This abstract class must be implemented in order to define a specific exclusive choice in the context of a process control flow.

Life cycle

This class is state-less, it is instantiated each time the control flow of the process instance has reached a condition node.
Example of Condition.

It is recommended to use ConditionBean instead, because ConditionBean allows to declare input and output parameters. By this way, the bean is more dynamic and reusable (no dependent on data context variables).

public abstract boolean evaluateCondition(ConditionContext aContext)
                                   throws OperationException

This method is automatically executed when the control flow reaches an exclusive choice (or condition).

It is not recommended for an implementation of this method to have a persistent side-effect on the repository. For automatic updates on the repository, the class ScriptTask should be used instead.

Throws:

OperationException
