public class SerialRef extends Object implements Ref, Serializable, Cloneable
Ref object, which is the mapping in the
Java programming language of an SQL REF value.
The SerialRef class provides a constructor for
creating a SerialRef instance from a Ref
object and provides methods for getting and setting the Ref object.
| Constructor and Description |
|---|
SerialRef(Ref ref)
Constructs a
SerialRef object from the given Ref
object. |
| Modifier and Type | Method and Description |
|---|---|
Object |
clone()
Returns a clone of this
SerialRef. |
boolean |
equals(Object obj)
Compares this SerialRef to the specified object.
|
String |
getBaseTypeName()
Returns a string describing the base type name of the
Ref. |
Object |
getObject()
Returns an
Object representing the SQL structured type
to which this SerialRef object refers. |
Object |
getObject(Map<String,Class<?>> map)
Returns an
Object representing the SQL structured type
to which this SerialRef object refers. |
int |
hashCode()
Returns a hash code for this
SerialRef. |
void |
setObject(Object obj)
Sets the SQL structured type that this
SerialRef object
references to the given Object object. |
