Class SerialRef

java.lang.Object
  extended by javax.sql.rowset.serial.SerialRef
All Implemented Interfaces:
Serializable, Cloneable, Ref

public class SerialRef
extends Object
implements Ref, Serializable, Cloneable

A serialized mapping of a 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 Detail

SerialRef

public SerialRef(Ref ref)
          throws SerialException,
                 SQLException
Constructs a SerialRef object from the given Ref object.

Parameters:
ref - a Ref object; cannot be null
Throws:
SQLException - if a database access occurs; if ref is null; or if the Ref object returns a null value base type name.
SerialException - if an error occurs serializing the Ref object
Method Detail

getBaseTypeName

public String getBaseTypeName()
                       throws SerialException
Returns a string describing the base type name of the Ref.

Specified by:
getBaseTypeName in interface Ref
Returns:
a string of the base type name of the Ref
Throws:
SerialException - in no Ref object has been set

getObject

public Object getObject(Map<String,Class<?>> map)
                 throws SerialException
Returns an Object representing the SQL structured type to which this SerialRef object refers. The attributes of the structured type are mapped according to the given type map.

Specified by:
getObject in interface Ref
Parameters:
map - a java.util.Map object containing zero or more entries, with each entry consisting of 1) a String giving the fully qualified name of a UDT and 2) the Class object for the SQLData implementation that defines how the UDT is to be mapped
Returns:
an object instance resolved from the Ref reference and mapped according to the supplied type map
Throws:
SerialException - if an error is encountered in the reference resolution
See Also:
Ref.setObject(java.lang.Object)

getObject

public Object getObject()
                 throws SerialException
Returns an Object representing the SQL structured type to which this SerialRef object refers.

Specified by:
getObject in interface Ref
Returns:
an object instance resolved from the Ref reference
Throws:
SerialException - if an error is encountered in the reference resolution
See Also:
Ref.setObject(java.lang.Object)

setObject

public void setObject(Object obj)
               throws SerialException
Sets the SQL structured type that this SerialRef object references to the given Object object.

Specified by:
setObject in interface Ref
Parameters:
obj - an Object representing the SQL structured type to be referenced
Throws:
SerialException - if an error is encountered generating the the structured type referenced by this SerialRef object
