Method Detail

applyAsDouble

T applyAsDouble(double v1,
                double v2)

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

Parameters:

v1 - first argument value

v2 - second argument value

Returns:

result value

apply

default T apply(java.lang.Double v1,
                java.lang.Double v2)

Default implementation. This uses applyAsDouble(double, double).

Specified by:

apply in interface java.util.function.BiFunction<java.lang.Double,java.lang.Double,T>

Parameters:

v1 - first argument

v2 - second argument

Returns:

result value

Throws:

java.lang.NullPointerException - if either argument is null

partial1

@NotNull
default java.util.function.DoubleFunction<T> partial1(double argument)

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

Parameters:

argument - value applied for first argument

Returns:

partially evaluated function

partial2

@NotNull
default java.util.function.DoubleFunction<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

andThen

@NotNull
default <R> DoubleFunction2<R> andThen(@NotNull
                                                java.util.function.Function<? super T,? extends R> after)

Get a chained function which first applies this function and then the given function to the returned value.

Specified by:

andThen in interface java.util.function.BiFunction<java.lang.Double,java.lang.Double,T>

Specified by:

andThen in interface java.util.function.Function<ITuple2<? extends java.lang.Double,? extends java.lang.Double>,T>

Specified by:

andThen in interface Function1<T,ITuple2<? extends java.lang.Double,? extends java.lang.Double>>

Specified by:

andThen in interface Function2<T,java.lang.Double,java.lang.Double>

Type Parameters:

R - result type of returned function

Parameters:

after - function to apply after this one

Returns:

function chain
