  Description copied from interface: Persistence
  Creates and returns a new query object. The query object is used to execute a query against persistent storage and fetch the results of the query. The query parameter types are specified prehand. If a particular parameter type is unknown, null may be used and type checking will defer to query execution.

  query - The query expression

  types - List of all parameter types, or null

  Returns:

  A new query object that can be executed

  Throws:

  QueryException - The query is invalid

                         Identity identity)
                  throws PersistenceException

  Description copied from interface: Persistence
  Creates a new object in persistence storage. Called for an object that was created during the transaction when the identity of that object is known. Creates a new record in persistence storage. Must detect an attempt to create an object with the same identity and must retain a lock on the object after creation. If the identity is null, an identity might be created and returned by this method.

  Specified by:

  create in interface Persistence

  conn - An open connection

  entity - The fields to store

  identity - The object's identity

  Returns:

  The object's identity

  Throws:

  PersistenceException - An object with the same identity already exists in persistent storage or any other persistence error occured.

• store

  public void store​(java.lang.Object conn,
                    Identity identity,
                    ProposedEntity newentity,
                    ProposedEntity oldentity)
             throws PersistenceException

  Description copied from interface: Persistence
  Stores the object in persistent storage, given the object fields and its identity. The object has been loaded before or has been created through a call to Persistence.create(org.exolab.castor.jdo.Database, java.lang.Object, org.castor.persist.ProposedEntity, org.exolab.castor.persist.spi.Identity). This method should detect whether the object has been modified in persistent storage since it was loaded. After this method returns all locks on the object must be retained until the transaction has completed. This method may return a new stamp to track further updates to the object.

  If the object was not retrieved for exclusive access, this method will be asked to perform dirty checking prior to storing the object. The original argument will contains the object's original fields as retrieved in the transaction, and stamp the object's stamp returned from a successful call to Persistence.load(java.lang.Object, org.castor.persist.ProposedEntity, org.exolab.castor.persist.spi.Identity, org.exolab.castor.mapping.AccessMode). These arguments are null for objects retrieved with an exclusive lock.

  Specified by:

  store in interface Persistence

  Parameters:

  conn - An open connection

  identity - The object's identity

  newentity - The fields to store

  oldentity - The original fields, or null

  Throws:

  PersistenceException - The object has been modified in persistence storage since it was last loaded or has been deleted from persitence storage or any other persistence error occored.

• delete

  public void delete​(java.lang.Object conn,
                     Identity identity)
              throws PersistenceException

  Description copied from interface: Persistence
  Deletes the object from persistent storage, given the object' identity. The object has been loaded before or has been created through a call to Persistence.create(org.exolab.castor.jdo.Database, java.lang.Object, org.castor.persist.ProposedEntity, org.exolab.castor.persist.spi.Identity). After this method returns all locks on the object must be retained until the transaction has completed.

  Specified by:

  delete in interface Persistence

  Parameters:

  conn - An open connection

  identity - The object's identity

  Throws:

  PersistenceException - A persistence error occured

• load

  public void load​(java.lang.Object conn,
                   ProposedEntity entity,
                   Identity identity,
                   AccessMode accessMode)
            throws PersistenceException

  Loads the object from persistence storage. This method will load the object fields from persistence storage based on the object's identity. This method may return a stamp which can be used at a later point to determine whether the copy of the object in persistence storage is newer than the cached copy (see store(java.lang.Object, org.exolab.castor.persist.spi.Identity, org.castor.persist.ProposedEntity, org.castor.persist.ProposedEntity)). If lock is true the object must be locked in persistence storage to prevent concurrent updates.

  Specified by:

  load in interface Persistence

  Parameters:

  conn - An open connection

  entity - An Object[] to load field values into

  identity - Identity of the object to load.

  accessMode - The access mode (null equals shared)

  Throws:

  PersistenceException - A persistence error occured

• toString

  public java.lang.String toString()

  Overrides:

  toString in class java.lang.Object
