javax.sql.rowset.serial
Class SerialStruct

java.lang.Object
  extended by javax.sql.rowset.serial.SerialStruct
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 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<String,Class<?>> 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<String,Class<?>> 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[] getAttributes()
          Retrieves an array of Object values containing the attributes of the SQL structured type that this SerialStruct object represents.
 Object[] getAttributes(Map<String,Class<?>> 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 getSQLTypeName()
          Retrieves the SQL type name for this SerialStruct object.

Constructor Detail

SerialStruct

public SerialStruct(Struct in,
                    Map<String,Class<?>> map)
             throws SerialException
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.

Parameters:
map - a java.util.Map object in which each entry consists of 1) a String object 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
Throws:
SerialException - if an error occurs

SerialStruct

public SerialStruct(SQLData in,
                    Map<String,Class<?>> map)
             throws SerialException
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. 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.

Parameters:
in - an instance of the SQLData class that defines the mapping of the SQL structured type to one or more objects in the Java programming language
map - a java.util.Map object in which each entry consists of 1) a String object 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
Throws:
SerialException - if an error occurs
Method Detail

getSQLTypeName

public String getSQLTypeName()
                      throws SerialException
Retrieves the SQL type name for this SerialStruct object. This is the name used in the SQL definition of the structured type

Specified by:
getSQLTypeName in interface Struct
Returns:
a String object representing the SQL type name for the SQL structured type that this SerialStruct object represents
Throws:
SerialException - if an error occurs

getAttributes

public Object[] getAttributes()
                       throws SerialException
Retrieves an array of Object values containing the attributes of the SQL structured type that this SerialStruct object represents.

Specified by:
getAttributes in interface Struct
Returns:
an array of Object values, with each element being an attribute of the SQL structured type that this SerialStruct 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 this SerialStruct represents as an array of Object values, using the given type map for custom mapping if appropriate.

Specified by:
getAttributes in interface Struct
Parameters:
map - a java.util.Map object in which each entry consists of 1) a String object 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 array of Object values, with each element being an attribute of the SQL structured type that this SerialStruct object represents
Throws:
SerialException - if an error occurs
