Getting started in JOAFIP usage

by the example: code sample
more details: feature and usage

below an artless example to help unterstand basic principle:

private final File storageDirectory = new File("runtime");

private FilePersistence filePersistence;

private IDataAccessSession session;

/** open file persistence */
public static void openFilePersistence() throws Exception {

final
FilePersistenceBuilder builder = new
FilePersistenceBuilder();

builder.setPathName(storageDirectory,);

builder.setRemoveFiles(false,);

builder.setGarbageManagement(false,);

filePersistence = builder.build();

session
= filePersistence.createDataAccessSession();

}

/** close file persistence saving */
public static void closeFilePersistenceSave() throws Exception {

if (session.isOpened()) {

session.close(EnumFilePersistenceCloseAction.SAVE);

}
filePersistence.close();

}

/** close file persistence do not save */
public static void closeFilePersistenceDoNotSave() throws Exception {

if (session.isOpened()) {

session.close(EnumFilePersistenceCloseAction.DO_NOT_SAVE);

}
filePersistence.close();

}

/** open session */
public static void openSession() throws Exception {

session.open();

}

/** close session saving */
public static void closeSession() throws Exception {

session.close(EnumFilePersistenceCloseAction.SAVE);

}

/** write an object */
public static void writeObject(final String key, final Object object) throws Exception {

session.setObject(key,
object);

}

/** read an object */
public static Object readObject(final String key) throws Exception {

return session.getObject(key);

}

public static void main(final String[] args) {

try {

openFilePersistence();
openSession();
MyEntity entity=getObject("myEntity");
if( entity==null ) {

entity=new MyEntity();
setObject("myEntity",entity);

}
entity.anOperation(...);
closeSession();
... some other operations ...
closeFilePersistenceSave();

} catch(Exception e) {

e.printStackTrace();

}
