Return a new tuple by prepending the element to this tuple.
Return a new tuple by prepending the element to this tuple.
This operation is O(this.size)
Return a new tuple by concatenating this tuple with that tuple.
Return a new tuple by concatenating this tuple with that tuple.
This operation is O(this.size + that.size)
Given a tuple (a1, ..., am), returns the tuple (an+1, ..., am) consisting
all its elements except the first n ones.
Given a tuple (a1, ..., am), returns the tuple (an+1, ..., am) consisting
all its elements except the first n ones.
Called on a tuple (a1, ..., an), returns a new tuple (f(a1), ..., f(an)).
Called on a tuple (a1, ..., an), returns a new tuple (f(a1), ..., f(an)).
The result is typed as (F[A1], ..., F[An]) if the tuple type is fully known.
If the tuple is of the form a1 *: ... *: Tuple (that is, the tail is not known
to be the cons type.
Given a tuple (a1, ..., am), returns a pair of the tuple (a1, ..., an)
consisting of the first n elements, and the tuple (an+1, ..., am) consisting
of the remaining elements.
Given a tuple (a1, ..., am), returns a pair of the tuple (a1, ..., an)
consisting of the first n elements, and the tuple (an+1, ..., am) consisting
of the remaining elements.
Given a tuple (a1, ..., am), returns the tuple (a1, ..., an) consisting
of its first n elements.
Given a tuple (a1, ..., am), returns the tuple (a1, ..., an) consisting
of its first n elements.
Given two tuples, (a1, ..., an) and (a1, ..., an), returns a tuple
((a1, b1), ..., (an, bn)).
Given two tuples, (a1, ..., an) and (a1, ..., an), returns a tuple
((a1, b1), ..., (an, bn)). If the two tuples have different sizes,
the extra elements of the larger tuple will be disregarded.
The result is typed as ((A1, B1), ..., (An, Bn)) if at least one of the
tuple types has a EmptyTuple tail. Otherwise the result type is
(A1, B1) *: ... *: (Ai, Bi) *: Tuple
Inherited methods
A method that should be called from every well-designed equals method that is open to be overridden in a subclass.
A method that should be called from every well-designed equals method that is open to be overridden in a subclass. See Programming in Scala, Chapter 28 for discussion and design.
- Value Params
- that
the value being probed for possible equality
- Returns
true if this instance can possibly equal
that, otherwise false- Inherited from

The nth element of this product, 0-based.
The nth element of this product, 0-based. In other words, for a
product A(x1, ..., xk), returns x(n+1) where 0 <= n < k.
- Value Params
- n
the index of the element to return
- Returns
the element

- IndexOutOfBoundsException
if the
nis out of range(n < 0 || n >= productArity).
- Inherited from
- Product
The name of the nth element of this product, 0-based.
The name of the nth element of this product, 0-based. In the default implementation, an empty string.
- Value Params

- Returns
in the default implementation, an

A string used in the toString methods of derived classes.
A string used in the toString methods of derived classes.
Implementations may override this method to prepend a string prefix
to the result of toString methods.
