AbstractStateManager (DataNucleus Core 4.1.17-SNAPSHOT API)

java.lang.Object
- org.datanucleus.state.AbstractStateManager<T>

All Implemented Interfaces:

ObjectProvider<T>

Direct Known Subclasses:

StateManagerImpl
```
public abstract class AbstractStateManager<T>
extends Object
implements ObjectProvider<T>
```
Abstract representation of an implementation of a bytecode enhancement-based StateManager. This class should have no reference to any JDO class, so it can be reused by a JPAStateManager too (in the future).

The difference is, it's possible for an object's state to be P_DIRTY, yet have no "dirty" fields because flush() has been called at least once during the transaction.

    setAssociatedValue in interface ObjectProvider<T>
    
    Parameters:
    
    key - Key for the value
    
    value - The associated value
  - getAssociatedValue
```
public Object getAssociatedValue(Object key)
```
