Method Detail

main

public static void main(java.lang.String[] args)

setUp

public void setUp()
           throws PBFactoryException

Throws:

PBFactoryException

tearDown

public void tearDown()

testHandlingOfMultiplePKFields

public void testHandlingOfMultiplePKFields()
                                    throws java.lang.Exception

not really a reference test, here we check handling of objects with multiple PK fields. Such an object was used in following reference tests.

Throws:

java.lang.Exception

testStoreWithMultiplePK_1

public void testStoreWithMultiplePK_1()
                               throws java.lang.Exception

Throws:

java.lang.Exception

testStoreWithMultiplePK_2

public void testStoreWithMultiplePK_2()
                               throws java.lang.Exception

Throws:

java.lang.Exception

testStoreWithMultiplePK_3

public void testStoreWithMultiplePK_3()
                               throws java.lang.Exception

Throws:

java.lang.Exception

testStoreReferencesMappedToSameTable

public void testStoreReferencesMappedToSameTable()

testGetReferencesByIdentityMappedToSameTable

public void testGetReferencesByIdentityMappedToSameTable()

testQueryReferencesMappedToSameTable

public void testQueryReferencesMappedToSameTable()

testDeleteReferencesMappedToSameTable

public void testDeleteReferencesMappedToSameTable()

testRepositoryFKStore

public void testRepositoryFKStore()

This test does the same as the testRepositoryFKStore(), but the used mapping data differ. ReferenceTest.RepositoryFK defines all the reference fields as primary key in field-descriptors. Further on the used database table declares the reference fields as PK too. Based on a user post: > The following fails to be stored by PersistenceBroker: > > I have a class ACL which has two primary keys: objectId and userFK, and > userFK is also a foreign key tied to a reference of type User. If I do this: > > persistentBroker.beginTransaction(); > ACL acl = new ACL(); > acl.setObjectId( 100 ); > acl.setUser( currentUser ); > persistentBroker.store(acl); > persistentBroker.commitTransaction(); > > Acl will not be saved. The reason seems to be because in the storeToDb() > method of the PersistentBroker, there first comes an assertion of the > PrimaryKeys and afterwards comes the assignment of all the foreign keys. In > the scenario above the assertion of the primary keys will fail, because the > userFK has not been assigned yet, so we have an incomplete set of primary > keys. This does work with the ODMG layer, probably because of a different > sequence of events during the storing of the object. > > I wonder if there should be a check whether a primary key is shared by the > foreign key and allow that assignment before the assertion of the primary > keys is performed. Any ideas? > > Cheers, > --Bill.
