Interface MappingConfigurationStrategy

All Known Implementing Classes:

GormMappingConfigurationStrategy

public interface MappingConfigurationStrategy

This interface defines a strategy for reading how persistent properties are defined in a persistent entity.

Subclasses can implement this interface in order to provide a different mechanism for mapping entities such as annotations or XML.

Since:

1.0

Method Summary

IdentityMapping	getDefaultIdentityMapping(ClassMapping classMapping) Obtains the default manner in which identifiers are mapped.
PersistentProperty	getIdentity(Class javaClass, MappingContext context) Obtains the identity of a persistent entity
Set	getOwningEntities(Class javaClass, MappingContext context) Returns a set of entities that "own" the given entity.
List<PersistentProperty>	getPersistentProperties(Class javaClass, MappingContext context)
List<PersistentProperty>	getPersistentProperties(Class javaClass, MappingContext context, ClassMapping mapping) Obtains a List of PersistentProperty instances for the given Mapped class
boolean	isPersistentEntity(Class javaClass) Tests whether the given class is a persistent entity

Method Detail

isPersistentEntity

boolean isPersistentEntity(Class javaClass)

Tests whether the given class is a persistent entity

Parameters:

javaClass - The java class

Returns:

true if it is a persistent entity

getPersistentProperties

List<PersistentProperty> getPersistentProperties(Class javaClass,
                                                 MappingContext context)

getPersistentProperties

List<PersistentProperty> getPersistentProperties(Class javaClass,
                                                 MappingContext context,
                                                 ClassMapping mapping)

Obtains a List of PersistentProperty instances for the given Mapped class

Parameters:

javaClass - The Java class

context - The MappingContext instance

mapping - The mapping for this class

Returns:

The PersistentProperty instances

getIdentity

PersistentProperty getIdentity(Class javaClass,
                               MappingContext context)

Obtains the identity of a persistent entity

Parameters:

javaClass - The Java class

context - The MappingContext

Returns:

A PersistentProperty instance

getDefaultIdentityMapping

IdentityMapping getDefaultIdentityMapping(ClassMapping classMapping)

Obtains the default manner in which identifiers are mapped. In GORM this is just using a property called 'id', but in other frameworks this may differ. For example JPA expects an annotated @Id property

Parameters:

classMapping - The ClassMapping instance

Returns:

The default identifier mapping

getOwningEntities

Set getOwningEntities(Class javaClass,
                      MappingContext context)

Returns a set of entities that "own" the given entity. Ownership dictates default cascade strategies. So if entity A owns entity B then saves, updates and deletes will cascade from A to B

Parameters:

javaClass - The Java class

context - The MappingContext

Returns:

A Set of owning classes
