ManagedInitializationContext (Flink : Runtime 2.0.0 API)

All Known Subinterfaces:

FunctionInitializationContext, StateInitializationContext

All Known Implementing Classes:

StateInitializationContextImpl
```
public interface ManagedInitializationContext
```
This interface provides a context in which operators can initialize by registering to managed state (i.e. state that is managed by state backends).
Operator state is available to all operators, while keyed state is only available for operators after keyBy.
For the purpose of initialization, the context signals if the state is empty (new operator) or was restored from a previous execution of this operator.
