Method Details

fetch

public final <B> int fetch(Datum.Accessor<B,?> acc,
 B buffer,
 int offset,
 Attribute a)

Method invoked internally when this Adapter is used to fetch a value; not intended for use in application code.

fetchNull

public int fetchNull(Attribute a)

Determines the mapping of SQL null.

If not overridden, this implementation throws an SQLDataException with SQLSTATE 22002, null_value_no_indicator_parameter.
