public class STRUCT
This class has two roles.
Like other classes in oracle.sql. it is a value class. That is, once it is constructed the user should not change its contents.

Struct
object represents.getSQLTypeName
in interface java.sql.Struct
Struct
object is the generic representationjava.sql.SQLException
- if a database access error occurspublic java.lang.Object[] getAttributes() throws java.sql.SQLException
Struct
object represents. Each call returns a fresh array. This method uses the type map associated with the connection for customizations of the type mappings. If there is no entry in the connection's type map that matches the structured type that this Struct
object represents, the driver uses the standard mapping.
Conceptually, this method calls the method getObject
on each attribute of the structured type and returns a Java array containing the result.
getAttributes
in interface java.sql.Struct
java.sql.SQLException
- if a database access error occurspublic java.lang.Object[] getAttributes(java.util.Map map) throws java.sql.SQLException
Struct
object represents. Each call returns a fresh array. This method uses the given type map for customizations of the type mappings. If there is no entry in the given type map that matches the structured type that this Struct
object represents, the driver uses the standard mapping.
Conceptually, this method calls the method getObject
on each attribute of the structured type and returns a Java array containing the result.
