23 The table above shows the availability of functions
24 `hull`, `lower`, `upper`, `first` and `last` on intervals
25 and interval containers that are all of ['*constant time complexity*].
26 Find the functions description and some simple properties below.
29 [[['*Range*]] [Types] [Description] ]
30 [[`interval_type hull(const T&)`] [__S __M] [`hull(x)` returns the smallest interval that contains all intervals of an interval container `x`.] ]
31 [[`T hull(const T&, const T&)`] [__S __M] [`hull(i,j)` returns the smallest interval that contains intervals `i` abd 'j'.] ]
32 [[`domain_type lower(const T&)`] [__i __S __M][`lower(x)` returns the lower bound of an interval or interval container `x`.] ]
33 [[`domain_type upper(const T&)`] [__i __S __M][`upper(x)` returns the upper bound of an interval or interval container `x`.] ]
34 [[`domain_type first(const T&)`] [__i __S __M][`first(x)` returns the first element of an interval or interval container `x`.
35 `first(const T&)` is defined for a discrete `domain_type` only.] ]
36 [[`domain_type last(const T&)`] [__i __S __M][`last(x)` returns the last element of an interval or interval container `x`.
37 `last(const T&)` is defined for a discrete `domain_type` only.] ]

42 lower(hull(x)) == lower(x)
43 upper(hull(x)) == upper(x)
44 first(hull(x)) == first(x)
45 last(hull(x)) == last(x)
