Otherwise, the instance will be initialized through the store as usual; however, in this case the store will be passed the given execution data, and the system will load the object according to the given fetch configuration (or the context's configuration, if the given one is null). Fields can optionally be excluded from required loading using the exclude mask. By default this method does not find new unflushed instances, validates, and does not throw an exception if a cached instance has been deleted concurrently. These options are controllable through the given OID_XXX flags.

public void setTrackChangesByType(boolean largeTransaction)
```
    Description copied from interface: StoreContext
    
    If a large number of objects will be created, modified, or deleted during this transaction setting this option to true will reduce memory usage if you perform periodic flushes by tracking changes at the type level instead of the instance level, resulting in more aggressive cache invalidation. Upon transaction commit the data cache will have to more aggressively flush objects. The store cache will have to flush instances of objects for each class of object modified during the transaction. A side benefit of large transaction mode is that smaller update messages can be used for RemoteCommitEvents. Defaults to false.

    Detach the specified objects from the broker. The objects returned can be manipulated and re-attached with Broker.attachAll(java.util.Collection, boolean, org.apache.openjpa.kernel.OpCallbacks). The detached instances will be unmanaged copies of the specified parameters, and are suitable for serialization and manipulation outside of a OpenJPA environment.

```
public void setAllowReferenceToSiblingContext(boolean allow)
```
    Description copied from interface: StoreContext
    
    Affirms if this context will allow its managed instances to refer instances that are managed by other contexts. Note: Some specification (such as JPA) does not warranty predictable behavior when strict group-like property of a persistent context (where managed instances can only refer to instances managed by the same context). Please be aware of consequences when the flag is set to true.
