Method Detail

initialize

public boolean initialize(com.solarmetric.rd.kodo.runtime.StateManagerImpl sm,
                          com.solarmetric.rd.kodo.runtime.JDOState state,
                          java.lang.Object connection)

Description copied from interface: StoreManager

Initialize the given StateManager. The oid of the StateManager will be set, and the meta field of the StateManager will be set to the class of the instance to load, or possibly one of its superclasses. Initialization involves first calling the StateManagerImpl.initialize(javax.jdo.spi.PersistenceCapable, com.solarmetric.rd.kodo.runtime.JDOState) method with a new instance of the correct type constructed with the JDOImplHelper#newInstance(Class,StateManager,Object) method (this will reset the meta field of the StateManager if the actual type was a subclass), then possibly loading fields if if desired. If this method is called during a data store transaction, the instance's database record should be locked. Version information can be loaded if desired through the StateManagerImpl.setVersion(java.lang.Object) method.

Specified by:

initialize in interface StoreManager

Overrides:

initialize in class DelegatingStoreManager

Parameters:

sm - the instance to initialize

state - the lifecycle state to initialize the state manager with

connection - the current connection information, or null if not given to the calling method of the persistence manager

Returns:

true if the matching instance exists in the data store, false otherwise

synchVersion

public boolean synchVersion(com.solarmetric.rd.kodo.runtime.StateManagerImpl sm,
                            java.lang.Object connection)

Description copied from interface: StoreManager

Update the version information in the given state manager to the version stored in the data store.

Specified by:

synchVersion in interface StoreManager

Overrides:

synchVersion in class DelegatingStoreManager

Parameters:

sm - the instance to check

connection - the current connection information, or null if not given to the calling method of the persistence manager

Returns:

true if the instance is up-to-date, false otherwise

load

public void load(com.solarmetric.rd.kodo.runtime.StateManagerImpl sm,
                 int field,
                 java.lang.Object connection)

Description copied from interface: StoreManager

Load the given StateManager. Note that any collection or map types loaded into the StateManager will be proxied with the correct type; therefore the StoreManager does not have to load the same concrete collection/map types as the instance declares. However, array types must be consistent with the array type stored by the PersistenceCapable instance. If this method is called during a data store transaction, the instance should be locked. If the given state manager does not have its version set already, version information can be loaded if desired through the StateManagerImpl.setVersion(java.lang.Object) method.

Specified by:

load in interface StoreManager

Overrides:

load in class DelegatingStoreManager

Parameters:

sm - the instance to load

field - the field to load; the field corrsponding to the metadata field at the given absolute index should be loaded; additional fields can be loaded if desired; attempting to load an additional field that has been dirtied will cause the load to be ignored

connection - the current connection information, or null if not given to the calling method of the persistence manager
