Class GormMappingConfigurationStrategy

java.lang.Object
  org.springframework.datastore.mapping.config.GormMappingConfigurationStrategy

All Implemented Interfaces:

MappingConfigurationStrategy

public class GormMappingConfigurationStrategy
extends Object
implements MappingConfigurationStrategy

This implementation of the MappingConfigurationStrategy interface will interpret GORM-style syntax for defining entities and associations.

Example in Groovy code:

  
      class Author {
          String name
          static hasMany = [books:Book]
      }
      class Book {
         String title
         static belongsTo = [author:Author]
        }

Method Detail

isPersistentEntity

public boolean isPersistentEntity(Class clazz)

Tests whether an class is a persistent entity Based on the same method in Grails core within the DomainClassArtefactHandler class

Specified by:

isPersistentEntity in interface MappingConfigurationStrategy

Parameters:

clazz - The java class

Returns:

True if it is a persistent entity

getPersistentProperties

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

Specified by:

getPersistentProperties in interface MappingConfigurationStrategy

See Also:

MappingConfigurationStrategy.getPersistentProperties(Class, MappingContext, ClassMapping)

getPersistentProperties

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

Description copied from interface: MappingConfigurationStrategy

Obtains a List of PersistentProperty instances for the given Mapped class

Specified by:

getPersistentProperties in interface MappingConfigurationStrategy

Parameters:

javaClass - The Java class

context - The MappingContext instance

classMapping - The mapping for this class

Returns:

The PersistentProperty instances

getAssociationMap

protected Map getAssociationMap(ClassPropertyFetcher cpf)

Retrieves the association map

Parameters:

cpf - The ClassPropertyFetcher instance

Returns:

The association map

getOwningEntities

public Set getOwningEntities(Class javaClass,
                             MappingContext context)

Description copied from interface: MappingConfigurationStrategy

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

Specified by:

getOwningEntities in interface MappingConfigurationStrategy

Parameters:

javaClass - The Java class

context - The MappingContext

Returns:

A Set of owning classes

getIdentity

public PersistentProperty getIdentity(Class javaClass,
                                      MappingContext context)

Description copied from interface: MappingConfigurationStrategy

Obtains the identity of a persistent entity

Specified by:

getIdentity in interface MappingConfigurationStrategy

Parameters:

javaClass - The Java class

context - The MappingContext

Returns:

A PersistentProperty instance

See Also:

MappingConfigurationStrategy.getIdentity(Class, org.springframework.datastore.mapping.MappingContext)

getDefaultIdentityMapping

public IdentityMapping getDefaultIdentityMapping(ClassMapping classMapping)

Description copied from interface: MappingConfigurationStrategy

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

Specified by:

getDefaultIdentityMapping in interface MappingConfigurationStrategy

Parameters:

classMapping - The ClassMapping instance

Returns:

The default identifier mapping
