Method Detail

flatten

public static <A> A[] flatten(Object[] data,
                              Class<A> cls,
                              int estimatedSize)

Makes a one-level array of non-array objects. The input array may contain objects of class A and A[] and A[][], etc. so the procedure can only be typed dynamically.

flatten

public static <A> A[] flatten(Object[] data,
                              Class<A> cls)

doFlatten

protected static <A> void doFlatten(List<A> list,
                                    Object datum,
                                    Class<A> cls)

map

public static <A,B> B[] map(Function<? super A,? extends B> fun,
                            Class<B> range,
                            A[] things)

map

public static <A,B> B[] map(Function<? super A,? extends B> fun,
                            Class<B> range,
                            Collection<? extends A> things)

append

public static <A> A[] append(Class<A> range,
                             A[]... parts)

append

public static <A> A[] append(A[] part1,
                             A[]... parts)

filter

public static <A> A[] filter(Predicate<? super A> pred,
                             Class<A> range,
                             A... things)
