filterImpl

@NotNull
public static <C extends java.util.Collection<? super T>,T> C filterImpl(@NotNull
                                                                                  C target,

                                                                                  java.util.Iterator<T> iterator,
                                                                                  @NotNull
                                                                                  java.util.function.Predicate<? super T> checker)

Filter the elements of an iterator into a collection.

This will add all filtered elements to the target collection.

Note that iterator is not allowed to be an iterator of the target collection, otherwise you'll get either a ConcurrentModificationException, or another exception because you are running into an endless loop.

Type Parameters:

C - collection type

T - filtered type

Parameters:

target - collection where the mapped elements are added

iterator - iterator providing the source elements

checker - value checker to decide which elements are kept

Returns:

reference to target, allowing to create it directly in the call
