public class VariableOneToOneMapping extends ObjectReferenceMapping implements RelationalMapping
Purpose: Variable one to one mappings are used to represent a pointer references between a java object and an implementer of an interface. This mapping is usually represented by a single pointer (stored in an instance variable) between the source and target objects. In the relational database tables, these mappings are normally implemented using a foreign key and a type code.

isRelationalMapping
public boolean isRelationalMapping()
INTERNAL:- Overrides:

-
addClassIndicator
public void addClassIndicator(java.lang.Class implementer, java.lang.Object typeIndicator)PUBLIC: Add a type indicator conversion to this mapping.
-
addClassNameIndicator
public void addClassNameIndicator(java.lang.String className, java.lang.Object typeIndicator)INTERNAL: Add indicators by classname. For use by the Mapping Workbench to avoid classpath dependencies
-
addForeignQueryKeyName
public void addForeignQueryKeyName(org.eclipse.persistence.internal.helper.DatabaseField sourceForeignKeyField, java.lang.String targetQueryKeyName)PUBLIC: A foreign key from the source table and abstract query key from the interface descriptor are added to the mapping. This method is used if there are multiple foreign keys.
-
addForeignQueryKeyName
public void addForeignQueryKeyName(java.lang.String sourceForeignKeyFieldName, java.lang.String targetQueryKeyName)PUBLIC: A foreign key from the source table and abstract query key from the interface descriptor are added to the mapping. This method is used if there are multiple foreign keys.
-
addTargetForeignQueryKeyName
public void addTargetForeignQueryKeyName(java.lang.String targetForeignQueryKeyName, java.lang.String sourcePrimaryKeyFieldName)PUBLIC: Define the target foreign key relationship in the Variable 1-1 mapping. This method is used for composite target foreign key relationships, that is the target object's table has multiple foreign key fields to the source object's primary key fields. Both the target foreign key query name and the source primary key field name must be specified. The distinction between a foreign key and target foreign key is that the variable 1-1 mapping will not populate the target foreign key value when written (because it is in the target table). Normally 1-1's are through foreign keys but in bi-directional 1-1's the back reference will be a target foreign key. In obscure composite legacy data models a 1-1 may consist of a foreign key part and a target foreign key part, in this case both method will be called with the correct parts.
