Method Detail

_4

_4 _4()

Retrieve the fourth element.

Returns:

the fourth element

into

default <R> R into(Fn4<? super _1,? super _2,? super _3,? super _4,? extends R> fn)

Destructure and apply this product to a function accepting the same number of arguments as this product's slots. This can be thought of as a kind of dual to uncurrying a function and applying a product to it.

Type Parameters:

R - the return type of the function

Parameters:

fn - the function to apply

Returns:

the result of applying the destructured product to the function

rotateL4

default Product4<_2,_3,_4,_1> rotateL4()

Rotate the first four values of this product one slot to the left.

Returns:

the left-rotated product

rotateR4

default Product4<_4,_1,_2,_3> rotateR4()

Rotate the first four values of this product one slot to the right.

Returns:

the right-rotated product

rotateL3

default Product4<_2,_3,_1,_4> rotateL3()

Description copied from interface: Product3

Rotate the first three values of this product one slot to the left.

Specified by:

rotateL3 in interface Product3<_1,_2,_3>

Returns:

the left-rotated product

rotateR3

default Product4<_3,_1,_2,_4> rotateR3()

Description copied from interface: Product3

Rotate the first three values of this product one slot to the right.

Specified by:

rotateR3 in interface Product3<_1,_2,_3>

Returns:

the right-rotated product

invert

default Product4<_2,_1,_3,_4> invert()

Description copied from interface: Product2

Rotate the first two slots of this product.

Specified by:

invert in interface Product2<_1,_2>

Specified by:

invert in interface Product3<_1,_2,_3>

Returns:

the rotated product

product

static <_1,_2,_3,_4> Product4<_1,_2,_3,_4> product(_1 _1,
                                                   _2 _2,
                                                   _3 _3,
                                                   _4 _4)

Static factory method for creating a generic Product4.

Type Parameters:

_1 - the first slot type

_2 - the second slot type

_3 - the third slot type

_4 - the fourth slot type

Parameters:

_1 - the first slot

_2 - the second slot

_3 - the third slot

_4 - the fourth slot

Returns:

the Product4
