org.jbpm.runtime.manager.impl

## Class AbstractRuntimeManager

- java.lang.Object
- - org.jbpm.runtime.manager.impl.AbstractRuntimeManager

- All Implemented Interfaces:
    org.kie.api.runtime.manager.RuntimeManager, org.kie.internal.runtime.manager.InternalRuntimeManager
  Direct Known Subclasses:
    PerCaseRuntimeManager, PerProcessInstanceRuntimeManager, PerRequestRuntimeManager, SingletonRuntimeManager

      public abstract class AbstractRuntimeManager
      extends Object
      implements org.kie.internal.runtime.manager.InternalRuntimeManager

  Common implementation that all `RuntimeManager` implementations should inherit from. Provides the following capabilities:
  - keeps track of all active managers by their identifier and prevents multiple managers from having the same id
  - provides a common close operation
  - injects the RuntimeManager into the ksession's environment for further reference
  - registers dispose callbacks (via transaction synchronization) to dispose of the runtime engine automatically on transaction completion
  - registers all defined items (work item handlers, event listeners)
  Additionally, this provides a abstract `init` method that will be called on RuntimeManager instantiation.
