Method Details

map

public final <V> PersistListTask<A,Optional<V>> map(PersistTask<T,V> task)

Deprecated.

Creates a composed task which applies the given task to each element of the result of this task and returns a list of all results.

The returned task will never return null. If the listTask did not return a value or the entity list is empty an empty List<Optional<T>> is returned.

flatMap

public final <V> PersistListTask<A,V> flatMap(PersistTask<T,V> task)

Deprecated.

Same as map(PersistTask) but filters out absent values and unwraps the remaining optionals.

filterWith

public final PersistListTask<A,T> filterWith(PersistTask<T,Boolean> predicate)

Deprecated.

Creates a new task that will execute this task and filters the resulting list by applying the given predicate task. Note, that the same predicate task is applied to each element, thus it must be stateless!
