Constructor Detail

ArrayType

public ArrayType(String role,
                 Class elementClass)

Method Detail

getReturnedClass

public Class getReturnedClass()

Description copied from interface: Type

The class returned by nullSafeGet() methods. This is used to establish the class of an array of this type.

Returns:

Class

---

instantiate

public PersistentCollection instantiate(SessionImplementor session,
                                        CollectionPersister persister)
                                 throws HibernateException

Specified by:

instantiate in class PersistentCollectionType

Throws:

HibernateException

---

nullSafeSet

public void nullSafeSet(PreparedStatement st,
                        Object value,
                        int index,
                        SessionImplementor session)
                 throws HibernateException,
                        SQLException

Description copied from interface: Type

Write an instance of the mapped class to a prepared statement. Implementors should handle possibility of null values. A multi-column type should be written to parameters starting from index.

Specified by:

nullSafeSet in interface Type

Overrides:

nullSafeSet in class PersistentCollectionType

Throws:

HibernateException

SQLException

---

getElementsIterator

public Iterator getElementsIterator(Object collection)

Not defined for collections of primitive type

Overrides:

getElementsIterator in class PersistentCollectionType

---

disassemble

public Serializable disassemble(Object value,
                                SessionImplementor session)
                         throws HibernateException

Description copied from interface: Type

Return a cacheable "disassembled" representation of the object.

Specified by:

disassemble in interface Type

Overrides:

disassemble in class PersistentCollectionType

Throws:

HibernateException

---

wrap

public PersistentCollection wrap(SessionImplementor session,
                                 Object array)

Specified by:

wrap in class PersistentCollectionType

---

isArrayType

public boolean isArrayType()

Overrides:

isArrayType in class PersistentCollectionType

---

toString

public String toString(Object value,
                       SessionFactoryImplementor factory)
                throws HibernateException

Description copied from interface: Type

A representation of the value to be embedded in an XML element.

Specified by:

toString in interface Type

Overrides:

toString in class PersistentCollectionType

Throws:

HibernateException

---

copy

public Object copy(Object original,
                   Object target,
                   SessionImplementor session,
                   Object owner,
                   Map copiedAlready)
            throws HibernateException

Specified by:

copy in interface Type

Overrides:
