Method Detail

apply

T apply(double v1,
        double v2,
        double v3,
        double v4)

Apply this function to three double arguments and return the result.

Parameters:

Parameters:

argument - value applied for first argument

Returns:

partially evaluated function

partial2

@NotNull
default DoubleFunction3<T> partial2(double argument)

Get a partially applied function where the second argument is fix.

Parameters:

argument - value applied for second argument

Returns:

partially evaluated function

partial3

@NotNull
default DoubleFunction3<T> partial3(double argument)

Parameters:

argument - value applied for third argument

Returns:

partially evaluated function

partial4

@NotNull
default DoubleFunction3<T> partial4(double argument)

Get a partially applied function where the fourth argument is fix.

Parameters:

argument - value applied for fourth argument

Returns:

partially evaluated function

andThen

@NotNull
default <R> DoubleFunction4<R> andThen(@NotNull
                                                java.util.function.Function<? super T,? extends R> after)
