Description copied from interface: ValueHandler

Map the given value and return all mapped columns, or simply return an array of unmapped default columns. The columns should have at least their Name and JavaType properties set.

name - use as a base to form column name(s); the column names of unmapped columns will automatically be made to fit database limitations

io - I/O information about mapped columns; you do not have to set this information if returning templates

adapt - whether to adapt the mapping or schema
