NAME
FBB::Iterator - Iterator returning plain values when dereferenced
FBB::ReverseIterator - reverse_iterator for FBB::Iterator
SYNOPSIS
#include <bobcat/iterator>
DESCRIPTION
The FBB::Iterator<Type> class template implements a bidirectional iterator for plain data
types. Dereferencing FBB::Iterator objects returns values of type Type, e.g., char or int.
This iterator comes in handy in case you need to initialize an objects with a range of
values, which are of some basic type (see also the EXAMPLE section).
FBB::ReverseIterator implements a reverse iterator for FBB::Iterator.
NAMESPACE
FBB
All constructors, members, operators and manipulators, mentioned in this man-page, are
defined in the namespace FBB.
INHERITS FROM
std::iterator<std::bidirectional_iterator_tag, ...>
CONSTRUCTORS
Constructors for Iterator<Type>:
o explicit Iterator(Tye const &value):
This constructor initializes the Iterator object with an initial Type value. When
dereferencing this iterator, value is returned.
The default implementations of the Iterator<Type>’s default, copy, and move constructors
are available.
Constructors for ReverseIterator<Type>:
o explicit ReverseIterator(Type const &value):
This constructor initializes the ReverseIterator object with an initial Type value.
When dereferencing this iterator immediately following its construction, the
decremented value is returned (without modifying the internally stored Type value);
o explicit ReverseIterator(Iterator<Type> const &iter):
This constructor initializes the ReverseIterator object with an initial
Iterator<Type> object. When dereferencing this iterator immediately following its
construction, the decremented Iterator’s value is returned (without modifying the
Type value that is stored inside the Iterator).
The default implementations of the ReverseIterator<Type>’s default, copy, and move
constructors are available.
MEMBER FUNCTIONS
For template parameter type Type all members of std::iterator<std:::reverse_iterator_tag,
Type> are available, as FBB::Iterator and FBB::ReverseIterator inherit from this class.
o Iterator<Type> &operator++():
The (prefix) increment operator increments the iterator’s value and returns a
reference to itself;
o Iterator<Type> &operator++(int):
The (postfix) increment operator increments the iterator’s value and returns a copy
of itself, initialized with the iterator’s value before it was incremented;
o Iterator<Type> &operator--():
The (prefix) decrement operator decrements the iterator’s value and returns a
reference to itself;
o Iterator<Type> &operator--(int):
The (postfix) decrement operator decrements the iterator’s value and returns a copy
of itself, initialized with the iterator’s value before it was decremented;
o bool operator==(Iterator<Type> const &rhs) const:
This operator returns true if the value of the current Iterator object is equal to
the value of the rhs Iterator object;
o bool operator!=(Iterator<Type> const &rhs) const:
This operator returns true if the value of the current Iterator object is not equal
to the value of the rhs Iterator object;
o Type &operator*():
The derefence operator returns a reference to the Iterator’s value.
o Type const &operator*() const:
This derefence operator returns a reference to the Iterator’s immutable value.
STATIC MEMBER FUNCTIONS
Static members of Iterator<Type>:
o Iterator<Type> last(Type value):
An Iterator<Type> object is returned initialized with ++value, so it can be
conveniently be used to create an inclusive iterator range (see also section
EXAMPLE);
o Iterator<Type> max():
An Iterator<Type> object is returned initialized with the value returned by
std::numeric_limits<Type>::max();
o Iterator<Type> min():
An Iterator<Type> object is returned initialized with the value returned by
std::numeric_limits<Type>::min()
Static member of ReverseIterator<Type>:
o ReverseIterator<Type> last(Type const &value):
A ReverseIterator<Type> object is returned initialized with
Iterator<Type>::last(value), so it can be conveniently be used to create an
inclusive reverse iterator range (see also section EXAMPLE);
EXAMPLE
#include <algorithm>
#include <iterator>
#include <iostream>
#include <string>
#include <bobcat/iterator>
using namespace std;
using namespace FBB;
int main()
{
copy(Iterator<int>(10), Iterator<int>(20),
ostream_iterator<int>(cout, ", "));
cout << ’\n’;
copy(Iterator<char>(*Iterator<char>::max() - 9),
Iterator<char>::last(*Iterator<char>::max()),
ostream_iterator<int>(cout, ", "));
cout << ’\n’;
cout << *Iterator<int>::max() << ’\n’;
copy(Iterator<int>(*Iterator<int>::max() - 9),
Iterator<int>::last(*Iterator<int>::max()),
ostream_iterator<int>(cout, ", "));
cout << ’\n’;
copy(ReverseIterator<int>(20), ReverseIterator<int>(10),
ostream_iterator<int>(cout, ", "));
cout << ’\n’;
std::string letters(Iterator<char>(’a’), Iterator<char>::last(’z’));
cout << letters << ’\n’;
std::string caps(ReverseIterator<char>::last(’Z’),
ReverseIterator<char>(’A’));
cout << caps << ’\n’;
