Method Detail

applyAsLong

long applyAsLong(int value1,
                 int value2,
                 int value3)

Apply this function to the given 3 arguments.

Parameters:

value1 - first argument

value2 - second argument

value3 - third argument

Returns:

the function result

partial1

@NotNull
default IntToLongFunction2 partial1(int value1)

View this function as one with 2 arguments using a fix first argument.

Parameters:

value1 - fix first argument

Returns:

function expecting the remaining 2 arguments in order

partial2

@NotNull
default IntToLongFunction2 partial2(int value2)

View this function as one with 2 arguments using a fix second argument.

Parameters:

value2 - fix second argument

Returns:

function expecting the remaining 2 arguments in order

partial3

@NotNull
default IntToLongFunction2 partial3(int value3)

View this function as one with 2 arguments using a fix third argument.

Parameters:

value3 - fix third argument

Returns:

function expecting the remaining 2 arguments in order

asIntToDoubleFunction

@NotNull
default IntToDoubleFunction3 asIntToDoubleFunction()

View this as a 2 int to double function.

Returns:

int to double function, due to precision restrictions sometimes not returning the original integral long values but an approximation
