Method Detail

clearCache

public void clearCache()

Specified by:

clearCache in interface PersistenceService

resolveProxy

public Object resolveProxy(Object o)

Specified by:

resolveProxy in interface PersistenceService

loadRepositoryDescriptor

public void loadRepositoryDescriptor(String ojbRepositoryFilePath)

Specified by:

loadRepositoryDescriptor in interface PersistenceService

retrieveNonKeyFields

public void retrieveNonKeyFields(Object persistableObject)

Specified by:

retrieveNonKeyFields in interface PersistenceService

Parameters:

persistableObject - object whose objects need to be filled in based on primary keys

See Also:

PersistenceService.retrieveNonKeyFields(java.lang.Object)

retrieveReferenceObject

public void retrieveReferenceObject(Object persistableObject,
                           String referenceObjectName)

Specified by:

retrieveReferenceObject in interface PersistenceService

Parameters:

persistableObject - object whose specified reference object needs to be filled in based on primary keys

referenceObjectName - the name of the reference object that will be filled in based on primary key values

See Also:

PersistenceService.retrieveReferenceObject(java.lang.Object, String referenceObjectName)

retrieveReferenceObjects

public void retrieveReferenceObjects(Object persistableObject,
                            List referenceObjectNames)

Specified by:

retrieveReferenceObjects in interface PersistenceService

Parameters:

persistableObject - object whose specified reference objects need to be filled in based on primary keys

referenceObjectNames - the names of the reference objects that will be filled in based on primary key values

See Also:

PersistenceService.retrieveReferenceObject(java.lang.Object, String referenceObjectName)

retrieveReferenceObjects

public void retrieveReferenceObjects(List persistableObjects,
                            List referenceObjectNames)

Specified by:

retrieveReferenceObjects in interface PersistenceService

Parameters:

persistableObjects - objects whose specified reference objects need to be filled in based on primary keys

referenceObjectNames - the names of the reference objects that will be filled in based on primary key values

See Also:

PersistenceService.retrieveReferenceObject(java.lang.Object, String referenceObjectName)

getFlattenedPrimaryKeyFieldValues

public String getFlattenedPrimaryKeyFieldValues(Object persistableObject)

Specified by:

getFlattenedPrimaryKeyFieldValues in interface PersistenceService

Parameters:

persistableObject - object whose primary key field name,value pairs you want

Returns:

a String representation of the primary key fields and values for the given persistableObject

See Also:

PersistenceService.getFlattenedPrimaryKeyFieldValues(java.lang.Object)

linkObjects

public void linkObjects(Object persistableObject)

For each reference object to the parent persistableObject, sets the key values for that object. First, if the reference object already has a value for the key, the value is left unchanged. Otherwise, for non-anonymous keys, the value is taken from the parent object. For anonymous keys, all other persistableObjects are checked until a value for the key is found.

Specified by:

linkObjects in interface PersistenceService

Parameters:

persistableObject - object whose objects need to have keys filled

See Also:

org.kuali.rice.krad.service.PersistenceService#getReferencedObject(java.lang.Object, org.apache.ojb.broker.metadata.ObjectReferenceDescriptor)

allForeignKeyValuesPopulatedForReference

public boolean allForeignKeyValuesPopulatedForReference(PersistableBusinessObject bo,
                                               String referenceName)

Description copied from interface: PersistenceService

This method examines whether all the foreign key fields for the specified reference contain values.

Specified by:

allForeignKeyValuesPopulatedForReference in interface PersistenceService

Returns:

true if they all are accessible and have values, false otherwise

See Also:

org.kuali.rice.krad.service.PersistenceService#allForeignKeyValuesPopulatedForReference(org.kuali.rice.krad.bo.BusinessObject, java.lang.String)

refreshAllNonUpdatingReferences

public void refreshAllNonUpdatingReferences(PersistableBusinessObject bo)

Description copied from interface: PersistenceService

This method refreshes all reference objects to this main object that are 'non-updateable'. In general, this means that if a reference object is configured to not be updated when the parent document is saved, then they are non-updated. This will not refresh updateable objects, which can cause problems when you're creating new objects. See PersistenceServiceImpl.isUpdateableReference() for the full logic.

Specified by:

refreshAllNonUpdatingReferences in interface PersistenceService

Parameters:

bo - - the businessObject to be refreshed

See Also:

org.kuali.rice.krad.service.PersistenceService#refreshAllNonUpdatingReferences(org.kuali.rice.krad.bo.BusinessObject)

isProxied

public boolean isProxied(Object object)

Asks persistenceDao if this represents a proxy

Specified by:

isProxied in interface PersistenceService

Parameters:

object - the object to determine if it is a proxy

Returns:

true if the object is an ORM proxy; false otherwise

See Also:

PersistenceService.isProxied(java.lang.Object)

setPersistenceDao

public void setPersistenceDao(PersistenceDao persistenceDao)

Sets the persistenceDao attribute value.

Parameters:

persistenceDao - The persistenceDao to set.
