Constructor Detail

XMLStoreManager

public XMLStoreManager(org.datanucleus.ClassLoaderResolver clr,
               org.datanucleus.PersistenceNucleusContext ctx,
               Map<String,Object> props)

Constructor.

Parameters:

clr - ClassLoader resolver

ctx - Context

props - Properties for this store manager

Method Detail

close

public void close()

Release of resources

Specified by:

close in interface org.datanucleus.store.StoreManager

Overrides:

close in class org.datanucleus.store.AbstractStoreManager

getJAXBHandler

public JAXBHandler getJAXBHandler()

getClassNameForObjectID

public String getClassNameForObjectID(Object id,
                             org.datanucleus.ClassLoaderResolver clr,
                             org.datanucleus.ExecutionContext ec)

Specified by:

getClassNameForObjectID in interface org.datanucleus.store.StoreManager

Overrides:

getClassNameForObjectID in class org.datanucleus.store.AbstractStoreManager

getClassNameForIdentity

public String getClassNameForIdentity(org.datanucleus.ExecutionContext ec,
                             String[] possibleNames,
                             Object id)

Method to return which of the possible class names for an identity corresponds to an object in the datastore. ONLY SUPPORTS SINGLE-FIELD IDENTITY.

Parameters:

ec - execution context

possibleNames - The possible class names of the object

id - The identity

Returns:

The class name of the object it corresponds to

getSupportedOptions

public Collection getSupportedOptions()

Accessor for the supported options in string form.

Specified by:

getSupportedOptions in interface org.datanucleus.store.StoreManager

Overrides:

getSupportedOptions in class org.datanucleus.store.AbstractStoreManager

Returns:

The supported options

getStrategyForNative

public String getStrategyForNative(org.datanucleus.metadata.AbstractClassMetaData cmd,
                          int absFieldNumber)

Method defining which value-strategy to use when the user specifies "native". Returns "generate-id" no matter what the field is. Override if your datastore requires something else.

Overrides:

getStrategyForNative in class org.datanucleus.store.AbstractStoreManager

Parameters:

cmd - Class requiring the strategy

absFieldNumber - Field of the class

Returns:

Just returns "generate-id".

getStrategyValueForGenerator

protected Object getStrategyValueForGenerator(org.datanucleus.store.valuegenerator.ValueGenerator generator,
                                  org.datanucleus.ExecutionContext ec)

Accessor for the next value from the specified generator. This implementation simply returns generator.next(). Any case where the generator requires datastore connections should override this method.

Overrides:

getStrategyValueForGenerator in class org.datanucleus.store.AbstractStoreManager

Parameters:

generator - The generator

ec - ExecutionContext

Returns:

The next value.
