Next, you should create a session to interact with the engine. Again, the API is knowledge-based, supporting different types of Knowledge, with a specific extension for each Knowledge Type. The following code snippet shows how easy it is to create a session based on the earlier created Knowledge Base, and to start a process.
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); ProcessInstance processInstance = ksession.startProcess("com.sample.ruleflow");
The ProcessRuntime
interface defines all the session methods
for interacting with processes, as shown below. Consult the Javadocs to get
a detailed explanation for each of the methods.
ProcessInstance startProcess(String processId); ProcessInstance startProcess(String processId, Map<String, Object> parameters); void signalEvent(String type, Object event); Collection<ProcessInstance> getProcessInstances(); ProcessInstance getProcessInstance(long id); WorkItemManager getWorkItemManager();
