Method Detail

orDefault

public static <T,R> R orDefault(Supplier<T> supplier,
                                      Function<T,R> function,
                                      R fallback)

Type Parameters:

T - argument type

R - return type

Parameters:

supplier - The supplier

function - The function to apply

fallback - The value to return if the supplied arg is null

Returns:

Applies a single argument function to the supplied argument and returns the result if the arg is not null, else returns the fallback value

orNull

public static <T,R> R orNull(Supplier<T> supplier,
                                   Function<T,R> function)

orElse

public static <T> boolean orElse(Supplier<T> supplier,
                                 Predicate<T> function,
                                 boolean fallback)

orElse

public static <T> boolean orElse(Supplier<T> supplier,
                                 Predicate<T> function)

orDefault

public static <T> int orDefault(Supplier<T> supplier,
                                ToIntFunction<T> function,
                                int fallback)

                           ToIntFunction<T> function)

ifPresent

public static <T> void ifPresent(Supplier<T> supplier,
