This package contains the implementation of the File/Object Store JDO R= eference + Implementation (FOStore, pronounced "foster").

+

This file provides information for implementors and maintainers of the = package.

+

Identity in FOStore and provisional ID's

+

All objects created by the client have a datastore-provided ID, called = an Object + Id (OID.java). Part of the OID represents the class of the object; these= id's + are called Class Id's and are separately managed (CLID.java). When an ob= ject + is made persistent:

+
+ 
Employee emp =3D new Employee("John Doe", 12345);
+ 
PersistenceManager pm =3D PersistenceManagerFactory.getPersistenceM=
anager();
+ 
pm.makePersistent(emp);
+
+

the object is assigned a "provisional" OID, assigned by the c= lient, + not by the datastore. When a real OID is required (getObjectId) or the t= ransaction + commits, the user's object is then flushed to the store, and a real ID i= s provided. + The datastore provides a datastore ID corresponding to the provisional I= D=2E

+

The mapping from provisional to real id's is maintained by both the cli= ent + and the store. The client maintains it on a per-PMF basis (in FOStorePMF= .java). + The store maintains it for all clients (currently a single map, which is= incorrect + as it should be per-client; see FOStoreDatabase.java).

+

Similar tables are kept, separately, for CLIDs. These tables are in FOS= toreModel.java + on the client side, and in FOStoreDatabase.java on the store side. Recal= l that + the OID of an object contains the CLID of the class of the object. If no= instances + of that class have yet been stored, then the OID contains a provisional = CLID. + The process of storing the object also stores a representation of the ob= ject's + class, and creates a datastore-provided CLID.

+

The need for each of the tables is as follows:

+

OID, client: Assume a persistent object is created, and put into a pers= istent + graph structure. Assume further that the object is comitted, but not the= graph + structure. At that point, the graph still refers to the object by its pr= ovisional + OID. Having this table allows us to find the real object ID.

+

OID, store: Assume a graph structure of new objects is to be stored, in= which + a single object is referenced more than once. Each time it is referenced= , it + is with the provisional ID assigned by the client. The store must ensure= that + an object is only assigned a single datastore ID, and this table ensures= that.

+

CLID, client: StoreManager implementations are required to be able to p= rovide + a java.lang.Class given an OID. When assigning OIDs, FOStore will never = use + a provisional CLID if the datastore-provided CLID is available. However,= it + is possible that two objects of the same class are created, and one is s= tored. + The CLID table in FOStoreMetaData will, after the store, only the datast= ore-provided + ID. If one then asks the store manager for the class of the unstored obj= ect + by it's OID, we still have to provide the right answer. By keeping a map= ping + of provisional IDs to datastore IDs in this table, we can do so.

+

CLID, store: Exactly the same reasoning as for the OID table in the sto= re: + ensuring that a given class is only ever assigned a single CLID.

+

Storing and Fetching Objects

+

Objects are stored in the database by way of InsertRequest, and fetched= by +way of FetchRequest. Each contains several methods to store and fetch Java +types. If in the unlikely event that more primitive types are added to Ja= va, +they will have to be added here. Also, support will have to be added to +FieldManager, which is outside of FOStore in the common package, and to it= 's +implementation in the fostore package, in AbstractFieldManager

+

More likely, however, is the need to extend the set of non-primitive ty= pes, + such as Collection types, that FOStore supports. Support for these lies = in 2 + files: CLID.java and the various XXXTranscriber.java files. The f= irst + keeps a table of "known" CLID's, which maps between a java.lan= g=2EClass + and a compiletime-fixed CLID. The latter has a Transcriber class for eac= h of + the known CLID's, for instance LocaleTranscriber writes and reads java.u= til.Locale + objects to/from I/O streams.
