Interface KieBase

All Superinterfaces:
  KieBaseEventManager

    public interface KieBase

extends KieBaseEventManager

The KieBase is a repository of all the application's knowledge definitions. It will contain rules, processes, functions, type models. The KieBase itself does not contain runtime data, instead sessions are created from the KieBase in which data can be inserted and process instances started.

Method Summary
`Set<String>` | `getEntryPointIds()` Returns the set of the entry points declared and/or used in this knowledge base
`FactType` | `getFactType(String packageName, String typeName)` Returns the FactType identified by the given package and type names.
`KiePackage` | `getKiePackage(String packageName)` Returns a reference to the KnowledgePackage identified by the given name.
`Collection<KiePackage>` | `getKiePackages()` Return an immutable collection of the packages that exist in this KieBase.
`Collection<? extends KieSession>` | `getKieSessions()` Return a collection of the StatefulKnowledgeSessions that exist in this KnowledgeBase.
`Process` | `getProcess(String processId)` Returns a referent to the Process identified by the given processId

`Query` | `getQuery(String packageName, String queryName)` Returns a reference to the Rule identified by the given package and rule names.
`Rule` | `getRule(String packageName, String ruleName)` Returns a reference to the Rule identified by the given package and rule names.
`KieSession` | `newKieSession()` Create a new StatefulKnowledgeSession using the default session configuration.
`KieSession` | `newKieSession(KieSessionConfiguration conf, Environment environment)` Create a new StatefulKnowledgeSession using the given session configuration and/or environment.
`StatelessKieSession` | `newStatelessKieSession()` Create a new StatelessKnowledgeSession using the default session configuration.
`StatelessKieSession` | `newStatelessKieSession(KieSessionConfiguration conf)` Create a new StatelessKnowledgeSession using the given session configuration.
