• java.lang.Object
  • imaginary.persist.Persistent

Fields Summary
private static final CustomerPeer	peer
private AccountSet	accounts
private String	first_name
private String	last_name

Constructors Summary
public Customer() Constructs a new Customer. super();

Methods Summary
public synchronized RemoteAccountSet	getAccountSet() return the AccountSet of accounts for this customer return accounts;
public RemoteAccount[]	getAccounts() Each customer has one or more accounts stored in an account set. This method provides those accounts in an array format. return an array of customer accounts // getPersistents() is all the synchronization we need RemotePersistent[] obs = accounts.getPersistents(); RemoteAccount[] accts = new RemoteAccount[obs.length]; // This trick is needed to make a Persistent[] an Account[] for(int i=0; i<obs.length; i++) { accts[i] = (RemoteAccount)obs[i]; } return accts;
public synchronized java.lang.String	getFirstName() return the customer's first name return first_name;
public synchronized java.lang.String	getLastName() return the customer's last name return last_name;
protected synchronized imaginary.persist.PersistentPeer	getPersistentPeer() return this object's PersistentPeer return Customer.peer;
public synchronized void	restore(imaginary.persist.Transaction trans, java.util.Hashtable data) The Customer implementation of the Persistent interface's restore() method. This takes a Hashtable of values and assigns them to attributes in the Customer object. param trans the Transaction being used for the restore param data the Hashtable of data pulled from the data store exception imaginary.persist.PersistenceException An error occurred restoring the Customer Hashtable hash = new Hashtable(); /* * Depending on your data store and table structure, the * Hashtable may have different keys */ // Set the ID setId(((Integer)data.get(CustomerPeer.CUST_ID)).intValue()); // Set the last name last_name = (String)data.get(CustomerPeer.LAST_NAME); // Set the first name first_name = (String)data.get(CustomerPeer.FIRST_NAME); // Create an account set try { accounts = new AccountSet(); } catch( RemoteException e ) { throw new PersistenceException(e); } // Create a Hashtable that tells the AccountSet what customer ID // to use for restoring the accounts hash.put("cust_id", new Integer(getId())); // Restore all accounts for this customer accounts.restore(trans, hash);
public synchronized void	setId(java.util.Hashtable h) The Persistent interface mandates that implementors provide a setId(Hashtable) method that pulls the ID out of a Hashtable and calls setId(int). param h a Hashtable of values from the data store see imaginary.persist.Persistent#setId // CustomerPeer defines the key for cust_id in the data store setId(((Integer)h.get(CustomerPeer.CUST_ID)).intValue());
