Field Detail

PLUS

static final LongOperator2 PLUS

PLUS (+) operator.

MINUS

static final LongOperator2 MINUS

MINUS (-) operator.

MULT

static final LongOperator2 MULT

MULTIPLICATION (*) operator.

DIV

static final LongOperator2 DIV

DIVISION (/) operator.

MOD

MODULO (%) operator.

Method Detail

partialLeft

@NotNull
default LongOperator1 partialLeft(long argument)

Get a partially applied function.

Parameters:

argument - value applied for first argument

Returns:

partially evaluated function

partialRight

@NotNull
default LongOperator1 partialRight(long argument)

Get a partially applied function.

Parameters:

argument - value applied for second argument

Returns:

partially evaluated function

andThen

@NotNull
default LongOperator2 andThen(@NotNull
                                       LongOperator1 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 LongOperator2 from(@NotNull
                                   java.util.function.LongBinaryOperator operator)

Make a standard unary long operator usable as LongOperator2. This is useful if you want to make use of the extended functionality of this implementation.

Parameters:

operator - operator to be used as a LongOperator2

Returns:

LongOperator2 view of the incoming operator, or possibly just a cast if operator already has the correct type
