Method Detail

loadRepositoryDescriptor

void loadRepositoryDescriptor(String ojbRepositoryFilePath)

clearCache

void clearCache()

resolveProxy

Object resolveProxy(Object o)

getPrimaryKeyFieldValues

Map getPrimaryKeyFieldValues(Object persistableObject)

Parameters:

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

Returns:

a Map containing the names and values of fields specified the given class which are designated as key fields in the OJB repository file

Throws:

IllegalArgumentException - if the given Object is null

ClassNotPersistableException - if the given object is of a type not described in the OJB repository

getPrimaryKeyFieldValues

Map getPrimaryKeyFieldValues(Object persistableObject,
                             boolean sortFieldNames)

Parameters:

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

sortFieldNames - if true, the returned Map will iterate through its entries sorted by fieldName

Returns:

a Map containing the names and values of fields specified the given class which are designated as key fields in the OJB repository file

Throws:

IllegalArgumentException - if the given Object is null

ClassNotPersistableException - if the given object is of a type not described in the OJB repository

retrieveNonKeyFields

void retrieveNonKeyFields(Object persistableObject)

Parameters:

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

Throws:

IllegalArgumentException - if the given Object is null

ClassNotPersistableException - if the given object is of a type not described in the OJB repository

retrieveReferenceObject

void retrieveReferenceObject(Object persistableObject,
                             String referenceObjectName)

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

Throws:

IllegalArgumentException - if the given Object is null

ClassNotPersistableException - if the given object is of a type not described in the OJB repository

retrieveReferenceObjects

void retrieveReferenceObjects(Object persistableObject,
                              List referenceObjectNames)

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

Throws:

IllegalArgumentException - if either of the given lists is null or empty, or if any of the referenceObjectNames is blank

ClassNotPersistableException - if the given object is of a type not described in the OJB repository

retrieveReferenceObjects

void retrieveReferenceObjects(List persistableObjects,
                              List referenceObjectNames)

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

Throws:

IllegalArgumentException - if either of the given lists is null or empty, or if any of the referenceObjectNames is blank

ClassNotPersistableException - if the given object is of a type not described in the OJB repository

linkObjects

void linkObjects(Object persistableObject)

Parameters:

persistableObject - object whose objects need to have keys filled

Throws:

IllegalArgumentException - if the given Object is null

ClassNotPersistableException - if the given object is of a type not described in the OJB repository

getFlattenedPrimaryKeyFieldValues

String getFlattenedPrimaryKeyFieldValues(Object persistableObject)

Parameters:

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

bounded - - whether to restrict the number of rows returned

Returns:

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

Throws:

IllegalArgumentException - if the given Object is null

ClassNotPersistableException - if the given object is of a type not described in the OJB repository

allForeignKeyValuesPopulatedForReference

boolean allForeignKeyValuesPopulatedForReference(PersistableBusinessObject bo,
                                                 String referenceName)

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

Parameters:

bo -

referenceName -

Returns:

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

refreshAllNonUpdatingReferences

void refreshAllNonUpdatingReferences(PersistableBusinessObject bo)

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.

Parameters:

bo - - the businessObject to be refreshed

isProxied

boolean isProxied(Object object)

Determines if the given object is proxied by the ORM or not

Parameters:

object - the object to determine if it is a proxy

Returns:

true if the object is an ORM proxy; false otherwise

isJpaEnabledForKradClass

boolean isJpaEnabledForKradClass(Class clazz)

Determines if JPA is enabled for the KNS and for the given class

Parameters:

clazz - the class to check for JPA enabling of

Returns:

true if JPA is enabled for the class, false otherwise
