Method Detail

clone

public <Z extends X> BasicAttribute<Z,T> clone(EntityTypeImpl<Z> type)

Clones the attribute.

This is used for cloning th attributes from Mapped Super Classes onto child types.

Specified by:

clone in class AttributeImpl<X,T>

Type Parameters:

Z - the new type

Parameters:

type - the owner type

Returns:

the new attribute

fillValue

                ManagedInstance<?> managedInstance,
                Object instance)

Fills the sequence / table generated value.

The operation returns false if at least one entity needs to obtain identity from the database.

Parameters:

type - the entity type

managedInstance - the managed instance

instance - the instance to fill ids.
