Class

equals

public boolean equals(Object x,
                      Object y)
               throws HibernateException

                          SQLException
Description copied from interface: CompositeUserType
Retrieve an instance of the mapped class from a JDBC resultset. Implementors should handle possibility of null values.

Specified by:
nullSafeGet in interface CompositeUserType
Parameters:
rs - a JDBC result set
names - the column names
owner - the containing entity
Returns:
Object
Throws:
HibernateException
SQLException

value - the object to write
index - statement parameter index
Throws:
HibernateException
SQLException

deepCopy

public Object deepCopy(Object value)
                throws HibernateException
Description copied from interface: CompositeUserType
Return a deep copy of the persistent state, stopping at entities and at collections.

Specified by:
deepCopy in interface CompositeUserType
Parameters:
value - generally a collection element or entity field
Returns:
Object a copy
Throws:
HibernateException

isMutable

public boolean isMutable()
Description copied from interface: CompositeUserType
Check if objects of this type mutable.

Specified by:
isMutable in interface CompositeUserType
Returns:
boolean

disassemble

public Serializable disassemble(Object value,
                                SessionImplementor session)
                         throws HibernateException
Description copied from interface: CompositeUserType
Transform the object into its cacheable representation. At the very least this method should perform a deep copy. That may not be enough for some implementations, however; for example, associations must be cached as identifier values. (optional operation)

Specified by:
disassemble in interface CompositeUserType
Parameters:
value - the object to be cached
Returns:
a cachable representation of the object
Throws:
HibernateException

assemble

public Object assemble(Serializable cached,
                       SessionImplementor session,
                       Object owner)
                throws HibernateException
Description copied from interface: CompositeUserType
Reconstruct an object from the cacheable representation. At the very least this method should perform a deep copy. (optional operation)

Specified by:
assemble in interface CompositeUserType
Parameters:
cached - the object to be cached
owner - the owner of the cached object
Returns:
a reconstructed object from the cachable representation
Throws:
HibernateException

replace

public Object replace(Object original,
                      Object target,
                      SessionImplementor session,
                      Object owner)
               throws HibernateException
Description copied from interface: CompositeUserType
During merge, replace the existing (target) value in the entity we are merging to with a new (original) value from the detached entity we are merging. For immutable objects, or null values, it is safe to simply return the first parameter. For mutable objects, it is safe to return a copy of the first parameter. However, since composite user types often define component values, it might make sense to recursively replace component values in the target object.

Specified by:
replace in interface CompositeUserType
Throws:
HibernateException
