- All Implemented Interfaces:
- Serializable, Cloneable, Struct
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 aStruct
object, a method for retrieving the SQL type name of the SQL structured type in the database, and methods for retrieving its attribute values.- See Also:

SerialStruct
public SerialStruct(Struct in, Map<String,Class<?>> map) throws SerialException
Constructs aSerialStruct
object from the givenStruct
object, using the givenjava.util.Map
object for custom mapping the SQL structured type or any of its attributes that are SQL structured types.- Parameters:
map
- ajava.util.Map
object in which each entry consists of 1) aString
object giving the fully qualified name of a UDT and 2) theClass
object for theSQLData
implementation that defines how the UDT is to be mapped- Throws:
SerialException
- if an error occurs- See Also:

SerialStruct
public SerialStruct(SQLData in, Map<String,Class<?>> map) throws SerialException
Constructs aSerialStruct
object from the givenSQLData
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. TheSQLData
object defines the class to which the SQL type will be mapped.- Parameters:
in
- an instance of theSQLData
class that defines the mapping of the SQL structured type to one or more objects in the Java programming languagemap
- ajava.util.Map
object in which each entry consists of 1) aString
object giving the fully qualified name of a UDT and 2) theClass
object for theSQLData
implementation that defines how the UDT is to be mapped- Throws:
SerialException
- if an error occurs

Method Detail

getSQLTypeName
public String getSQLTypeName() throws SerialException
Retrieves the SQL type name for thisSerialStruct
object. This is the name used in the SQL definition of the structured type- Specified by:
getSQLTypeName
in interfaceStruct
- Returns:
- a
String
object representing the SQL type name for the SQL structured type that thisSerialStruct
object represents - Throws:
SerialException
- if an error occurs
-
getAttributes
public Object[] getAttributes() throws SerialException
Retrieves an array ofObject
values containing the attributes of the SQL structured type that thisSerialStruct
object represents.- Specified by:
getAttributes
in interfaceStruct
- Returns:
- an array of
Object
values, with each element being an attribute of the SQL structured type that thisSerialStruct
object represents - Throws:
SerialException
- if an error occurs
-
getAttributes
public Object[] getAttributes(Map<String,Class<?>> map) throws SerialException
Retrieves the attributes for the SQL structured type that thisSerialStruct
represents as an array ofObject
values, using the given type map for custom mapping if appropriate.- Specified by:
getAttributes
in interfaceStruct
- Parameters:
map
- ajava.util.Map
object in which each entry consists of 1) aString
object giving the fully qualified name of a UDT and 2) theClass
object for theSQLData
implementation that defines how the UDT is to be mapped- Returns:
- an array of
Object
values, with each element being an attribute of the SQL structured type that thisSerialStruct
object represents - Throws:
SerialException
- if an error occurs
