javax.sql.rowset.serial.SerialStruct
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.
Thread safety
A SerialStruct is not safe for use by multiple concurrent threads. If a SerialStruct is to be used by more than one thread then access to the SerialStruct should be controlled by appropriate synchronization.
