execute

public void execute(ActivityExecution execution)
             throws Exception

Description copied from class: FlowNodeActivityBehavior

Default behaviour: just leave the activity with no extra functionality.

Specified by:

execute in interface CoreActivityBehavior<ActivityExecution>

Specified by:

execute in interface ActivityBehavior

Overrides:

execute in class FlowNodeActivityBehavior

Throws:

Exception
