NodeEngine (Hazelcast Root 3.12.9 API)

All Known Implementing Classes:

NodeEngineImpl
```
public interface NodeEngine
```
The NodeEngine is the 'umbrella' of services/service-method that gets injected into a ManagedService.
So if you are writing a custom SPI service, such as a stack-service, this service should probably implement the ManagedService so you can get access to the services within the system.

```
MemberVersion getVersion()
```
    Returns the codebase version of the node. For example, when running on hazelcast-3.8.jar, this would resolve to Version.of(3,8,0). A node's codebase version may be different than cluster version.
    
    Returns:
    
    codebase version of the node
    
    Since:
    
    3.8
