Interface IntOperator1

All Superinterfaces:

java.util.function.IntUnaryOperator

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

Field Detail

NEGATE

static final IntOperator1 NEGATE

Integer operator NEGATE. Beware: as with usual NEGATE not only 0 also Integer.MIN_VALUE is its own negative.

BIT_FLIP

static final IntOperator1 BIT_FLIP

Integer operator BIT FLIP (~).

Method Detail

partial

@NotNull
default IntOperator0 partial(int argument)

Create a zero argument function from this one by applying a constant argument. Although useless for pure functions it can be useful in cases where the zero argument function is a factory (and therefore not pure).

Parameters:

argument - constant argument

Returns:

zero argument function

andThen

@NotNull
default IntOperator1 andThen(@NotNull
                                      IntOperator1 after)

Create a function which applies this function and feeds the result into the next function.

Parameters:

after - function called with the result of this function

Returns:

chained function

from

@NotNull
static IntOperator1 from(@NotNull
                                  java.util.function.IntUnaryOperator operator)

Make a standard unary int operator usable as IntOperator1. This is useful if you want to make use of the extended functionality of this implementation.

Parameters:

operator - operator to be used as a IntOperator1

Returns:

IntOperator1 view of the incoming operator, or possibly just a cast if operator already has the correct type
