public interface UserType
This interface should be implemented by user-defined "types".
A "type" class is not the actual property type - it
is a class that knows how to serialize instances of another
class to and from JDBC.
This interface
for more complex cases,
Type| Method Summary | |
|---|---|
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,
Object owner)
Retrieve an instance of the mapped class from a JDBC resultset. |
void |
nullSafeSet(PreparedStatement st,
Object value,
int index)
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. |
