Constructor Detail

ArrayType

public ArrayType(TypeFactory.TypeScope typeScope,
                 java.lang.String role,
                 java.lang.String propertyRef,
                 java.lang.Class elementClass)

Method Detail

getReturnedClass

public java.lang.Class getReturnedClass()

Description copied from interface: Type

The class returned by Type.nullSafeGet(java.sql.ResultSet, java.lang.String[], org.hibernate.engine.spi.SharedSessionContractImplementor, java.lang.Object) methods. This is used to establish the class of an array of this type.

Returns:

The java type class handled by this type.

instantiate

public PersistentCollection instantiate(SharedSessionContractImplementor session,
                                        CollectionPersister persister,
                                        java.io.Serializable key)
                                 throws HibernateException

Description copied from class: CollectionType

Instantiate an uninitialized collection wrapper or holder. Callers MUST add the holder to the persistence context!

Specified by:

instantiate in class CollectionType

Parameters:

session - The session from which the request is originating.

persister - The underlying collection persister (metadata)

key - The owner key.

Returns:

The instantiated collection.

Throws:

HibernateException

getElementsIterator

public java.util.Iterator getElementsIterator(java.lang.Object collection)

Not defined for collections of primitive type

Overrides:

getElementsIterator in class CollectionType

Parameters:

collection - The collection to be iterated

Returns:

The iterator.

wrap

public PersistentCollection wrap(SharedSessionContractImplementor session,
                                 java.lang.Object array)

Description copied from class: CollectionType

Wrap the naked collection instance in a wrapper, or instantiate a holder. Callers MUST add the holder to the persistence context!

Specified by:

wrap in class CollectionType

Parameters:

session - The session from which the request is originating.

array - The bare collection to be wrapped.

Returns:

The wrapped collection.

isArrayType

public boolean isArrayType()

Overrides:

isArrayType in class CollectionType

toLoggableString

public java.lang.String toLoggableString(java.lang.Object value,
                                         SessionFactoryImplementor factory)
                                  throws HibernateException

Description copied from interface: Type

Generate a representation of the value for logging purposes.

Specified by:

toLoggableString in interface Type

Overrides:

toLoggableString in class CollectionType

Parameters:

value - The value to be logged

factory - The session factory

Returns:

The loggable representation

Throws:

HibernateException - An error from Hibernate

instantiateResult

public java.lang.Object instantiateResult(java.lang.Object original)

Description copied from class: CollectionType

Instantiate a new "underlying" collection exhibiting the same capacity charactersitcs and the passed "original".

Overrides:

instantiateResult in class CollectionType

Parameters:

original - The original collection.

Returns:

The newly instantiated collection.

replaceElements

public java.lang.Object replaceElements(java.lang.Object original,
                                        java.lang.Object target,
                                        java.lang.Object owner,
                                        java.util.Map copyCache,

                                 throws HibernateException

Description copied from class: CollectionType

Replace the elements of a collection with the elements of another collection.

Overrides:

instantiate

anticipatedSize - The anticipated size of the instaniated collection after we are done populating it.

Returns:

A newly instantiated collection to be wrapped.
