Deprecated.

Attempts to match the attribute name given for the class as a fk field to a reference class defined in the repository. Since a fk field can have references to many tables, this returns a list of all found.

Parameters:

attributeName -

Returns:

Map with attribue name as key of map and class as value

                             String attributeName)

Deprecated.

This method will return a Map of all the foreign key fields and the corresponding primary key fields for a given reference. The Map structure is: Key(String fkFieldName) => Value(String pkFieldName)

Parameters:

clazz - - Class that contains the named reference

attributeName - - Name of the member that is the reference you want foreign keys for

Returns:

returns a Map populated as described above, with one entry per foreign key field

getBusinessObjectAttributeClass

                                                                                  String attributeName)

Deprecated.

This method is a PersistableBusinessObject specifific utility method. If the Class clazz passed in is a descendent of PersistableBusinessObject, and if the attributeName specified exists on the object, then the class of this attribute named will be returned.

Parameters:

clazz - - class to be examined for the attribute's class

attributeName - - name of the class' attribute to be examined

Returns:

the class of the named attribute, if no exceptions occur

getNestedForeignKeyMap

Map getNestedForeignKeyMap(Class persistableObjectClass)

Deprecated.

Builds a map of reference pk attributes back to the foreign key.

Parameters:

persistableObjectClass -

Returns:

getForeignKeyFieldsPopulationState

ForeignKeyFieldsPopulationState getForeignKeyFieldsPopulationState(PersistableBusinessObject bo,
                                                                 String referenceName)

Deprecated.

This method checks the foreign keys for a reference on a given BO, and tests that all fk fields are populated if any are populated. In other words, for a given reference, it finds all the attributes of the BO that make up the foreign keys, and checks to see if they all have values. It also keeps a list of all the fieldNames that do not have values.

Parameters:

bo - - A populated BusinessObject descendent. Must contain an attributed named referenceName.

referenceName - - The name of the field that is a reference we are analyzing.

Returns:

A populated ForeignKeyFieldsPopulation object which represents the state of population for the foreign key fields.

listReferenceObjectFields

Map<String,Class> listReferenceObjectFields(Class boClass)

Deprecated.

This method uses the persistence layer to determine the list of reference objects contained within this parent object. For example, an Account object contains sub-objects such as Chart, as well as the key that connects the two, String chartOfAccountsCode. The return structure is: Map. As an example, an Account object passed into this would return: 0:['chartOfAccounts', org.kuali.module.chart.bo.Chart] 1:['organization', org.kuali.module.chart.bo.Org] etc.

Parameters:

boClass - Class that would like to be analyzed for reference names

Returns:

Map containing the reference name for the key as a string, and the class of the reference as the value. If the object contains no references, then this Map will be empty.

listReferenceObjectFields

Map<String,Class> listReferenceObjectFields(PersistableBusinessObject bo)

Deprecated.

This method uses the persistence layer to determine the list of reference objects contained within this parent object. For example, an Account object contains sub-objects such as Chart, as well as the key that connects the two, String chartOfAccountsCode. The return structure is: Map. As an example, an Account object passed into this would return: 0:['chartOfAccounts', org.kuali.module.chart.bo.Chart] 1:['organization', org.kuali.module.chart.bo.Org] etc.

Parameters:

bo - BusinessObject (or subclass) instance that would like to be analyzed for reference names

Returns:

Map containing the reference name for the key as a string, and the class of the reference as the value. If the object contains no references, then this Map will be empty.

listCollectionObjectTypes

Map<String,Class> listCollectionObjectTypes(Class boClass)

Deprecated.

listCollectionObjectTypes

Map<String,Class> listCollectionObjectTypes(PersistableBusinessObject bo)

Deprecated.

hasReference

boolean hasReference(Class boClass,
                   String referenceName)

Deprecated.

Returns whether there is a reference defined in the persistence layer with the given name. Depending on the type of underlying persistence mechanism, this method may or may not return true when the referenceName really refers to a collection type. To determine whether a reference is a collection, use the hasCollection method instead. In OJB, this method will return false for collection references.

Parameters:

boClass -

referenceName -

Returns:

hasCollection

boolean hasCollection(Class boClass,
                    String collectionName)

Deprecated.

Returns whether BOs of the given class have a collection defined within them with the given collection name.

Parameters:

boClass -

collectionName -

Returns:

isReferenceUpdatable

boolean isReferenceUpdatable(Class boClass,
                           String referenceName)

Deprecated.

isCollectionUpdatable

boolean isCollectionUpdatable(Class boClass,
                            String collectionName)

Deprecated.

getInverseForeignKeysForCollection

Map<String,String> getInverseForeignKeysForCollection(Class boClass,
                                                    String collectionName)

Deprecated.

Returns a listing of the FK field mappings between a BO and the elements in a collection. Since this is in effect a 1:n relationship, only the complete primary key set of the parent BO will be returned. for example, assume Account BO has an "acctNbrForAcct" PK, and it has a list of subAccounts, each of which has a ("acctNbrForSubAcct", "subAcctNbr") PK pair. the Account PK will be mapped to some of the PK fields of the element list. When called on the Account BO class with the "subAccounts" collection name, his method should return a map with a mapping of "acctNbrForAcct" (key) => "acctNbrForSubAcct"

Parameters:

boClass -

collectionName -

Returns:

getTableName

String getTableName(Class<? extends PersistableBusinessObject> boClass)

Deprecated.

Returns the name of the table underlying the business object class

Parameters:

boClass -

Returns:
