Class Summary

Modifier and Type	Class and Description
public class	AggregateCollectionMapping Purpose: The aggregate collection mapping is used to represent the aggregate relationship between a single source object and a collection of target objects.
public abstract class	AggregateMapping Purpose: Two objects can be considered to be related by aggregation if there is a strict 1:1 relationship between the objects.
public class	AggregateObjectMapping Purpose:Two objects can be considered to be related by aggregation if there is a strict 1:1 relationship between the objects.
public class	Association Purpose: Generic association object.
public abstract class	AttributeAccessor Purpose: This provides an abstract class for setting and retrieving the attribute value for the mapping from an object.
public abstract class	CollectionMapping Purpose: Abstract class for relationship mappings which store collection of objects
public abstract class	DatabaseMapping Purpose: Defines how an attribute of an object maps to and from the database Responsibilities: Define type of relationship (1:1/1:M/M:M/etc.) Define instance variable name and fields names required Define any additional properties (ownership, indirection, read only, etc.) Control building the value for the instance variable from the database row Control building the database fields from the object Control any pre/post updating/inserting/deleting required to maintain the relationship Merges object changes for unit of work. Clones objects for unit of work. cache computed information to optimize performance
public class	DirectCollectionMapping Purpose: This mapping is used to store a collection of simple types (String, Number, Date, etc.) into a single table.
public class	DirectMapMapping Mapping for a collection of key-value pairs.
public class	DirectToFieldMapping Purpose: Maps an attribute to the corresponding database field type.
public abstract class	ForeignReferenceMapping Purpose: Abstract class for relationship mappings
public class	ManyToManyMapping Purpose: Many to many mappings are used to represent the relationships between a collection of source objects and a collection of target objects.
public class	ManyToOneMapping Purpose: Define the relationship to be a ManyToOne.
public class	MultitenantPrimaryKeyMapping Purpose: Maps a multitenant property to the corresponding database field type.
public abstract class	ObjectReferenceMapping Purpose: Abstract class for 1:1, variable 1:1 and reference mappings
public class	OneToManyMapping Purpose: This mapping is used to represent the typical RDBMS relationship between a single source object and collection of target objects; where, on the database, the target objects have references (foreign keys) to the source object.
public class	OneToOneMapping Purpose: One to one mappings are used to represent a pointer references between two java objects.
public class	PropertyAssociation Purpose: Generic association object.
public class	RelationTableMechanism Purpose: Contains relation table functionality that was originally defined in ManyToManyMapping and now is shared with OneToOneMapping.
public class	TransformationMapping Purpose: A transformation mapping is used for a specialized translation between how a value is represented in Java and its representation on the databae.
public class	TypedAssociation Purpose: Generic association object.
public class	UnidirectionalOneToManyMapping Purpose: UnidirectionalOneToManyMapping doesn't have 1:1 back reference mapping.
public class	VariableOneToOneMapping Purpose: Variable one to one mappings are used to represent a pointer references between a java object and an implementer of an interface.
