NodeEngineImpl (Hazelcast Root 3.5 API)

java.lang.Object
- com.hazelcast.spi.impl.NodeEngineImpl

All Implemented Interfaces:

NodeEngine
```
public class NodeEngineImpl
extends Object
implements NodeEngine
```
The NodeEngineImpl is the where the construction of the Hazelcast dependencies take place. It can be compared to a Spring ApplicationContext. It is fine that we refer to concrete types, and it is fine that we cast to a concrete type within this class (e.g. to call shutdown). In an application context you get exactly the same behavior.
But the crucial thing is that we don't want to leak concrete dependencies to the outside. For example we don't leak OperationServiceImpl to the outside.
