Field Detail MISSING_ROW_ID final static int MISSING_ROW_ID(Code) NO_TABLE_INFO final static int NO_TABLE_INFO(Code) OBJECT_CAN_PERSIST final static int OBJECT_CAN_PERSIST(Code) Method Detail addIgnoreAssociation protected void addIgnoreAssociation(Class objectClass)(Code) Adds the class to the set of ignored associations. Parameters:   objectClass - the class to ignore canPersist protected boolean canPersist()(Code) Returns true if the object can be persistent. If an object doesn't have table information or row id information, it can not be persistent. true if the object can be persistent. classInIgnoreAssociation boolean classInIgnoreAssociation(Class objectClass)(Code) delete protected int delete(Database database) throws JPersistException(Code) Deletes the object from a matching database table using the jpersist.Database instance. Parameters:   database - a database instance throws:   JPersistException - delete protected int delete(DatabaseManager databaseManager) throws JPersistException(Code) Deletes the object from a matching database table using the jpersist.DatabaseManager instance. Parameters:   databaseManager - a database manager instance throws:   JPersistException - delete protected int delete(TransactionManager transactionManager) throws JPersistException(Code) Deletes the object from a matching database table using the jpersist.TransactionManager instance. Parameters:   transactionManager - a jpersist.TransactionManager instance throws:   JPersistException - getIgnoreAssociations protected boolean getIgnoreAssociations()(Code) Returns true is associations are being ignored and not loaded or saved, false otherwise. true is associations are being ignored and not loaded or saved, false otherwise. getObjectChecksum long getObjectChecksum()(Code) getObjectKeyValue protected Object getObjectKeyValue(Object key)(Code) Returns the key value that was originally loaded with the object. Even if the field in the object changes the original key's value remains for updates and deletes. Parameters:   key - a key field defined in the object the key value that was originally loaded with the object getObjectKeyValues Map getObjectKeyValues()(Code) getObjectPersistence protected int getObjectPersistence()(Code) Returns whether an object can be persistent, and the reason why or why not. Objects are checked during loading to see if they can be made persistent. If they can OBJECT_CAN_PERSIST will be returned. If the object can't persist, then the reason why, usually MISSING_ROW_ID, will be returned. whether an object can be persistent, and the reason why or why not getReloadAfterSave protected boolean getReloadAfterSave()(Code) Returns true if the object is to be reloaded following a save. true if the object is to be reloaded following a save. isPersistent protected boolean isPersistent()(Code) Returns true if object is in the persistent state (has been saved/loaded and will be updated) true if object is in the persistent state (has been saved/loaded and will be updated) makeObjectTransient protected void makeObjectTransient()(Code) Make object transient/new. Will insert instead of update. objectHasChanged protected boolean objectHasChanged()(Code) Returns true if the object has changed in some way and needs to be saved. true if the object has changed in some way and needs to be saved. removeIgnoreAssociation protected void removeIgnoreAssociation(Class objectClass)(Code) Removes the class from the set of ignored associations. Parameters:   objectClass - the class to remove save public int save(Database database) throws JPersistException(Code) Saves the object to a matching database table using the jpersist.Database instance. Parameters:   database - a database instance throws:   JPersistException - save public int save(DatabaseManager databaseManager) throws JPersistException(Code) Saves the object to a matching database table using the jpersist.DatabaseManager instance. Parameters:   databaseManager - a database manager instance throws:   JPersistException - save public int save(TransactionManager transactionManager) throws JPersistException(Code) Saves the object to a matching database table using the jpersist.TransactionManager instance. Parameters:   transactionManager - a jpersist.TransactionManager instance throws:   JPersistException - setIgnoreAssociations protected void setIgnoreAssociations(boolean ignoreAssociations)(Code) Set whether loads/saves ignore associations. Parameters:   ignoreAssociations - true to ignore saving/loading associations, false otherwise. setObjectChecksum void setObjectChecksum(long objectChecksum)(Code) setObjectHasChanged protected void setObjectHasChanged(boolean objectHasChanged)(Code) Set the state of the object to has changed which will cause it to be saved. Parameters:   objectHasChanged - true if the object has changed and needs to be saved setObjectPersistence void setObjectPersistence(int reason)(Code) setReloadAfterSave protected void setReloadAfterSave(boolean reloadAfterSave)(Code) Set whether objects are reloaded after saves. If the database changes any of the columns associated with an object, it should be reloaded. Parameters:   reloadAfterSave - true if the object is to be reloaded following a save Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
