Reconstruct the object from its disassembled state. This method is the reciprocal of Type.disassemble(java.lang.Object, org.hibernate.engine.spi.SessionImplementor, java.lang.Object)

Specified by:
assemble in interface Type
Overrides:
assemble in class AbstractType
Parameters:
cached - the disassembled state from the cache
session - the originating session
owner - the parent entity object
Returns:
the (re)assembled object
Throws:
HibernateException - An error from Hibernate

disassemble

public Serializable disassemble(Object value,
                                SessionImplementor session,
                                Object owner)
                         throws HibernateException
Description copied from interface: Type
Return a disassembled representation of the object. This is the value Hibernate will use in second level caching, so care should be taken to break values down to their simplest forms; for entities especially, this means breaking them down into their constituent parts.

Specified by:
disassemble in interface Type
Overrides:
disassemble in class AbstractType
Parameters:
value - the value to cache
session - the originating session
owner - optional parent entity object (needed for collections)
Returns:
the disassembled, deep cloned state
Throws:
HibernateException - An error from Hibernate

replace

public Object replace(Object original,
                      Object target,
                      SessionImplementor session,
                      Object owner,
                      Map copyCache)
               throws HibernateException
Description copied from interface: Type
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. For objects with component values, it might make sense to recursively replace component values.

Specified by:
replace in interface Type
Parameters:
original - the value from the detached entity being merged
target - the value in the managed entity
session - The originating session
owner - The owner of the value
copyCache - The cache of already copied/replaced values
Returns:
the value to be merged
Throws:
HibernateException - An error from Hibernate

                throws HibernateException
Description copied from interface: Type
Compare two instances of the class mapped by this type for persistence "equality" (equality of persistent state).

This should always equate to some form of comparison of the value's internal state. As an example, for something like a date the comparison should be based on its internal "time" state based on the specific portion it is meant to represent (timestamp, date, time).

Specified by:
isEqual in interface Type
Overrides:
isEqual in class AbstractType
Parameters:
x - The first value
y - The second value
Returns:
True if there are considered equal (see discussion above).
Throws:
HibernateException - A problem occurred performing the comparison

getHashCode

public int getHashCode(Object x)
Description copied from interface: Type
Get a hash code, consistent with persistence "equality". Again for most types the normal usage is to delegate to the value's hashCode.

Specified by:
getHashCode in interface Type
Overrides:
getHashCode in class AbstractType
Parameters:
x - The value for which to retrieve a hash code
Returns:
The hash code

getColumnSpan

public int getColumnSpan(Mapping mapping)
                  throws MappingException
Description copied from interface: Type

Specified by:
getColumnSpan in interface Type
Parameters:
mapping - The mapping object :/
Returns:
The number of columns
Throws:
MappingException - Generally indicates an issue accessing the passed mapping object.

getName

Description copied from interface: Type
Returns the abbreviated name of the type.

Specified by:
getName in interface Type
Returns:
String the Hibernate type name

getReturnedClass

public Class getReturnedClass()
Description copied from interface: Type

Specified by:
getReturnedClass in interface Type
Returns:
The java type class handled by this type.

isMutable

public boolean isMutable()
Description copied from interface: Type
Are objects of this type mutable. (With respect to the referencing object ... entities and collections are considered immutable because they manage their own internal state.)

Specified by:
isMutable in interface Type
Returns:
boolean

                          String columnName,
