Class StructDescriptor

java.lang.Object

oracle.sql.TypeDescriptor

oracle.sql.StructDescriptor

All Implemented Interfaces:

Serializable, oracle.jdbc.internal.ACProxyable, oracle.jdbc.internal.ObjectData, OracleData, OracleTypeMetaData, OracleTypeMetaData.Struct, ORAData

Deprecated.

Use factory method Connection.createStruct to create an instance of java.sql.Struct directly.

public class StructDescriptor
extends TypeDescriptor
implements oracle.jdbc.internal.OracleTypeMetaData.Struct, Serializable

Descriptor of a SQL structured object. (That is an SQL Object type). Its main responsibility is understanding how to convert between various representations of such a struct.

There should be a method to return information about the fields (beyond their number. But there is no public representation for that.
