Method Detail

getClassMetadata

private static org.hibernate.metadata.ClassMetadata getClassMetadata(org.springframework.dao.support.DaoSupport dao,
                                                                     Object model)

isEntity

public static boolean isEntity(org.springframework.dao.support.DaoSupport dao,
                               Object entityModelTemplate)

Parameters:

dao -

entityModelTemplate -

Returns:

true if the requested entityModelTemplate Object is managed by the persistent layer

getIdValue

public static Object getIdValue(org.springframework.dao.support.DaoSupport dao,
                                Object entityModelTemplate)

isNewModel

public static boolean isNewModel(org.springframework.dao.support.DaoSupport dao,
                                 Object model)

Checking if it is a new model (identifier == null) If the index is a compound index we must check all components if just one of them is null

Parameters:

index -

Returns:

deepCopyModel

public static Object deepCopyModel(org.springframework.dao.support.DaoSupport dao,
                                   Object entityModelTemplate)

This deepCopy will copy all properties of the template model but ignore the id. In case the id is a compound id the the resulting copy will get a deepCopy of the id if the composite id is only partially filled NOTE that the method will only create shallow copies except for component properties which will be deep copied This means that collections and associations will NOT be deep copied

Parameters:

dao -

entityModelTemplate -

Returns:

a copy of the entityModelTemplate

shallowCopyModel

public static Object shallowCopyModel(org.springframework.dao.support.DaoSupport dao,
                                      Object entityModelTemplate,
                                      boolean includeId)

This Hibernate specific code will create shallow copies of the model object

Parameters:

dao -

entityModelTemplate -

includeId - true if the id is to be included

Returns:

checkProvider

public static void checkProvider(org.springframework.dao.support.DaoSupport dao)

getIdValue_old

private static Serializable getIdValue_old(org.springframework.dao.support.DaoSupport dao,
                                           Object model)

getIdentifierPropertyName_old

private static String getIdentifierPropertyName_old(org.springframework.dao.support.DaoSupport dao,
                                                    Object model)

copyTemplate_Experimental

private static Object copyTemplate_Experimental(org.springframework.orm.hibernate3.support.HibernateDaoSupport dao,
                                                Object entityModelTemplate)
