## org.jbpm.runtime.manager.impl
Class SimpleRuntimeEnvironment

    java.lang.Object
      org.jbpm.runtime.manager.impl.SimpleRuntimeEnvironment

All Implemented Interfaces:
  SchedulerProvider, RuntimeEnvironment

Direct Known Subclasses:
  DefaultRuntimeEnvironment

    public class SimpleRuntimeEnvironment

extends Object
implements org.kie.internal.runtime.manager.RuntimeEnvironment, SchedulerProvider

The most basic implementation of `RuntimeEnvironment` that at the same time serves as base implementation for all extensions. Encapsulates all important configuration that `RuntimeManager` requires for execution.

- EntityManagerFactory - shared for all runtime engine build based on same `RuntimeEnvironment`
- Environment - Drools/jBPM environment object - will be cloned for every `RuntimeEngine`
- KieSessionConfiguration - will be build passed on defined properties - cloned for every `RuntimeEngine`
- KieBase - resulting knowledge base build on given assets or returned if it was preset
- RegisterableItemsFactory - factory used to provide listeners and work item handlers
- Mapper - mapper used to keep context information
- UserGroupCallback - user group callback, if not given null will be returned
- GlobalSchedulerService - since this environment implements `SchedulerProvider` it allows to get `GlobalTimerService` if available
