Class LinkedHashMapSelectOperation<K,R>

java.lang.Object
  org.sormula.operation.SqlOperation<R>
      org.sormula.operation.ScalarSelectOperation<R>
          org.sormula.operation.SelectOperation<R,java.util.Map<K,R>>
              org.sormula.operation.MapSelectOperation<K,R>
                  org.sormula.operation.LinkedHashMapSelectOperation<K,R>

Type Parameters:

K - key class type for row objects

R - Class associated with a row in table

public class LinkedHashMapSelectOperation<K,R>
extends MapSelectOperation<K,R>

MapSelectOperation that uses LinkedHashMap for SelectOperation.readAll() results. A LinkedHashMap allows you to order with ScalarSelectOperation.setOrderBy(String) so that the order is preserved in the resulting map and yet allow direct look up by primary key.
