Examples of org.drools.ruleflow.common.core.Process

org.drools.ruleflow.common.core.Process
Represents a some process definition. A process has a name and a unique id. When a new version of a process is created, the name stays the same, but the id and the version of the process should be different. Different types of processes could be defined (like RuleFlow). @author Kris Verlaenen
