StateManagerImpl (OpenJPA Parent POM 2.4.2 API)

java.lang.Object
- org.apache.openjpa.kernel.StateManagerImpl

All Implemented Interfaces:

Serializable, FieldConsumer, FieldManager, FieldSupplier, StateManager, OpenJPAStateManager
```
public class StateManagerImpl
extends Object
implements OpenJPAStateManager, Serializable
```
Implementation of the OpenJPAStateManager interface for use with this runtime. Each state manager manages the state of a single persistence capable instance. The state manager is also responsible for all communications about the instance to the StoreManager. The state manager uses the State pattern in both its interaction with the governed instance and its interaction with the broker. In its interactions with the persistence capable instance, it uses the FieldManager interface. Similarly, when interacting with the broker, it uses the PCState singleton that represents the current lifecycle state of the instance.

  - getImplData
```
public Object getImplData(int field)

    Description copied from interface: OpenJPAStateManager
    
    Use intermediate field data to store intermediate information that might be available before the field is fully loaded. The system will automatically clear this data when the field gets loaded.

```
    Description copied from interface: OpenJPAStateManager
    
    Set the value of the field with the given index as from the external object value. If there is no externalizer, this is equivalent to OpenJPAStateManager.storeField(int, java.lang.Object).

  - dirtyCheck
```
public void dirtyCheck()
```
    Checks whether or not _pc is dirty. In the cases where field tracking is not happening (see below), this method will do a state comparison to find whether _pc is dirty, and will update this instance with this information. In the cases where field tracking is happening, this method is a no-op.
    
    Fields are tracked for all classes that are run through the OpenJPA enhancer prior to or during deployment, and all classes (enhanced or unenhanced) in a Java 6 environment or newer.
    
    In a Java 5 VM or older:
    - instances of unenhanced classes that use property access and obey the property access limitations are tracked when the instances are loaded from the database by OpenJPA, and are not tracked when the instances are created by application code.
    - instances of unenhanced classes that use field access are never tracked.

  - setRemote
```
public void setRemote(int field,

```
    Description copied from interface: OpenJPAStateManager
    
    Set the given field to the given value. Make the field dirty as if user code set it. Do not delete dependent objects in the field's current value. This method is invoked by the remote package to synch a server-side state manager with remote changes. We do not need to delete dependent instances because they will have been deleted when the field changed on the client side, and those client-side deletes will be transmitted independently.
    
    Specified by:
    
    setRemote in interface OpenJPAStateManager

```
public Object newProxy(int field)
```
    Description copied from interface: OpenJPAStateManager
    
    Create a new hollow proxy instance for the given field. In cases where the field externalizes to an SCO but is declared something else, the returned object may not implement Proxy. In all other cases, this method delegates to the system ProxyManager with the correct field information. The returned proxy's owner is unset so that modifications to the proxy will not be tracked while its state is initialized. Calling OpenJPAStateManager.storeField(int, java.lang.Object) or OpenJPAStateManager.store(int, java.lang.Object) will set the proxy's owner automatically.
    
    Specified by:

public Object newFieldProxy(int field)
```
