| Modifier and Type | Method and Description |
|---|---|
List<Tuple> |
list(Expression<?>... args)
list the results for the given projection
An empty list is returned for no results.
|
<RT> List<RT> |
list(Expression<RT> projection)
list the results for the given projection
An empty list is returned for no results.
|
<K,V> Map<K,V> |
map(Expression<K> key,
Expression<V> value)
return the given projection as a Map instance using key and value for Map population
An empty map is returned for no results.
