Modifier and Type | Method and Description |
---|---|
Object |
assemble(Serializable cached,
Object owner)
Reconstruct an object from the cacheable representation.
|
Object |
deepCopy(Object value)
Return a deep copy of the persistent state, stopping at entities and at
collections.
|
Serializable |
disassemble(Object value)
Transform the object into its cacheable representation.
|
boolean |
equals(Object x,
Object y)
Compare two instances of the class mapped by this type for persistence "equality".
|
int |
hashCode(Object x)
Get a hashcode for the instance, consistent with persistence "equality"
|
boolean |
isMutable()
Are objects of this type mutable?
|
Object |
nullSafeGet(ResultSet rs,
String[] names,
SessionImplementor session,
Object owner)
Retrieve an instance of the mapped class from a JDBC resultset.
|
void |
nullSafeSet(PreparedStatement st,
Object value,
int index,
SessionImplementor session)
Write an instance of the mapped class to a prepared statement.
|
Object |
replace(Object original,
Object target,
Object owner)
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.
|
Class |
returnedClass()
The class returned by nullSafeGet().
|
int[] |
sqlTypes()
Return the SQL type codes for the columns mapped by this type.
