[hibernate-issues] [Hibernate-JIRA] Created: (HHH-7234) No way to get Object's type in nullSafeGet
No way to get Object's type in nullSafeGet
------------------------------------------
Key: HHH-7234
URL: https://hibernate.onjira.com/browse/HHH-7234
Project: Hibernate ORM
Issue Type: Bug
Components: core
Affects Versions: 4.1.0
Reporter: Vagif Kuliyev
I am trying to do the following:
public class SerUserType extends MutableUserType {
protected Class klass;
protected SerA ser=F.g(SerA.class);
public Class returnedClass() {
return klass;
}
public int[] sqlTypes() {
return new int[] {Types.BLOB};
}
public boolean equals(Object x, Object y) throws HibernateException {
return ObjectUtils.equals(x, y);
}
public Object deepCopy(Object value) {
klass=value.getClass();
Copyable copyable=(Copyable)value;
Object copy=copyable.copy();
return copy;
}
public Object nullSafeGet(ResultSet resultSet,String[] names,SessionImplementor
session,Object owner)
throws HibernateException,SQLException {
byte[] b=(byte[])BlobType.INSTANCE.nullSafeGet(resultSet,names,session,owner);
return ser.deser(b,klass);
}
public void nullSafeSet(PreparedStatement preparedStatement,Object value,int
index,SessionImplementor session)
throws HibernateException,SQLException {
BlobType.INSTANCE.nullSafeSet(preparedStatement,ser.ser(value),index,session);
}
}
However, this is not possible because it is not possible to access the object's class
in the nullSafeGet method. I propse that the object's class is passed to the
nullSafeGet in the UserType interface.
Regardless of whether is correct in functionality (I haven't tested), I think it would
be highly beneficial to know the runtime class of the object in the nullSafeGet metod.
