Interface CustomDatumFactory

All Superinterfaces:

oracle.jdbc.internal.ObjectDataFactory

public interface CustomDatumFactory

extends oracle.jdbc.internal.ObjectDataFactory

This interface complements CustomDatum. It is passed to getCustom methods to create specific kinds of objects.

Typical use is

      EmpFactory factory = new EmpFactory();
      OracleResultSet rs = ... ;
      Emp m = (Emp)rs.getCustom(n, factory);
      ...
  

Method Summary

CustomDatum

create(Datum d, int sqlType) create an Object from SQL Type and return it.

Method Detail

create

public CustomDatum create(Datum d,
                          int sqlType)
                   throws java.sql.SQLException

create an Object from SQL Type and return it. It is sometimes convenient to have the same class implement both CustomDatum and CustomDatumFactory, but normally they are distinct.

sqlType should really be a class of some sort, but introducing such a class would go well beyond the current state of JDBC and so for the moment we just provide the type code. Note that for named types (such as SQL Object types) the name can be determined from the Datum.

Parameters:

d - some SQL data that should be used to initialize an Object.

sqlType - the SQL type that the

Returns:

an Object that embeds information from d.

Throws:

java.sql.SQLException
