public class SerialStruct extends Object implements Struct, Serializable, Cloneable
A serialized mapping in the Java programming language of an SQL structured type. Each attribute that is not already serialized is mapped to a serialized form, and if an attribute is itself a structured type, each of its attributes that is not already serialized is mapped to a serialized form.
In addition, the structured type is custom mapped to a class in the Java programming language if there is such a mapping, as are its attributes, if appropriate.
The SerialStruct
class provides a constructor for creating
an instance from a Struct
object, a method for retrieving
the SQL type name of the SQL structured type in the database, and methods
for retrieving its attribute values.
Constructor Summary | |
---|---|
SerialStruct(SQLData in, Map map) Constructs a SerialStruct object from the
given SQLData object, using the given type
map to custom map it to a class in the Java programming
language.
|
|
SerialStruct(Struct in, Map map) Constructs a SerialStruct object from the given
Struct object, using the given java.util.Map
object for custom mapping the SQL structured type or any of its
attributes that are SQL structured types.
|
Method Summary | |
---|---|
Object[] |
Retrieves an array of Object values containing the
attributes of the SQL structured type that this
SerialStruct object represents.
|
Object[] |
getAttributes(Map map) Retrieves the attributes for the SQL structured type that this SerialStruct represents as an array of
Object values, using the given type map for
custom mapping if appropriate.
|
String |
Retrieves the SQL type name for this SerialStruct
object.

public SerialStruct(SQLData in, Map map) throws SerialException
SerialStruct
object from the
given SQLData
object, using the given type
map to custom map it to a class in the Java programming
language. The type map gives the SQL type and the class
to which it is mapped. The SQLData
object
defines the class to which the SQL type will be mapped.
