Description copied from interface: GeneratorMappingAdapter

Method to map the current record of a result set or the result of a callable statement to an object on the stack. indexes defines the SQL indexes for the result set to be used in functions such a getInt(index).

Specified by:

generateFromResult in interface GeneratorMappingAdapter

Parameters:

resultMapping - the result mapping

co - code emitter

result - ResultSet or CallableStatement local variable

indexes - array of SQL indexes
