Creates a non-strict view of a slice of this iterable collection
Creates a non-strict view of a slice of this iterable collection.
Note: the difference between view and slice is that view produces
a view of the current iterable collection, whereas slice produces a new iterable collection.
Note: view(from, to) is equivalent to view.slice(from, to)
Note: might return different results for different runs, unless the underlying collection type is ordered.
the index of the first element of the view
the index of the element following the view
a non-strict view of a slice of this iterable collection, starting at index from and extending up to (but not including) index until.

Creates a non-strict view of this iterable collection.
...
true iff ...
Creates a non-strict filter of this iterable collection
Creates a non-strict filter of this iterable collection.
Note: the difference between c filter p and c withFilter p is that
the former creates a new collection, whereas the latter only restricts
the domain of subsequent map, flatMap, foreach, and withFilter operations.
Note: might return different results for different runs, unless the underlying collection type is ordered.
the predicate used to test elements.
an object of class WithFilter, which supports
map, flatMap, foreach, and withFilter operations.
All these operations apply to those elements of this iterable collection which
satify the predicate p.
[use case] Returns a iterable collection formed from this iterable collection and another iterable collection by combining corresponding elements in pairs
Returns a iterable collection formed from this iterable collection and another iterable collection by combining corresponding elements in pairs. If one of the two collections is longer than the other, its remaining elements are ignored.
the type of the second half of the returned pairs
The iterable providing the second half of each result pair
a new iterable collection containing pairs consisting of
corresponding elements of this iterable collection and that. The length
of the returned collection is the minimum of the lengths of this iterable collection$ and that.

Note: might return different results for different runs, unless the underlying collection type is ordered.
the type of the first half of the returned pairs (this is always a supertype
of the collection's element type A).
the type of the second half of the returned pairs
the class of the returned collection. Where possible, That is
the same class as the current collection class Repr, but this
depends on the element type (A1, B) being admissible for that class,
which means that an implicit instance of type CanBuildFrom[Repr, (A1, B), That].

The iterable providing the second half of each result pair
an implicit value of class CanBuildFrom which determines the
result class That from the current representation type Repr and the new element type (A1, B).
a new collection of type That containing pairs consisting of
corresponding elements of this iterable collection and that. The length
of the returned collection is the minimum of the lengths of this iterable collection$ and that.
[use case] Returns a iterable collection formed from this iterable collection and another iterable collection by combining corresponding elements in pairs
Returns a iterable collection formed from this iterable collection and another iterable collection by combining corresponding elements in pairs. If one of the two collections is shorter than the other, placeholder elements are used to extend the shorter collection to the length of the longer.
the type of the second half of the returned pairs
The iterable providing the second half of each result pair
the element to be used to fill up the result if this iterable collection is shorter than that.
the element to be used to fill up the result if that is shorter than this iterable collection.
a new iterable collection containing pairs consisting of
corresponding elements of this iterable collection and that. The length
of the returned collection is the maximum of the lengths of this iterable collection$ and that.
If this iterable collection is shorter than that, thisElem values are used to pad the result.
If that is shorter than this iterable collection, thatElem values are used to pad the result.
