Header File
#include <rw/i18n/RWUAvailableEncodingListIterator.h>
Description
RWUAvailableEncodingListIterator is a Standard C++ bidirectional iterator for class RWUAvailableEncodingList. An instance of RWUAvailableEncodingListIterator can be used to access the list of encoding names currently recognized by the Internationalization Module. The list cannot be changed at run time.
Example
#include <rw/i18n/RWUAvailableEncodingList.h>
#include <iostream>
int
main()
{
// Iterate over the list of encodings and write them
// to std::cout, obtaining iterators from the static
// RWUAvailableEncodingList begin() and end() methods.
RWUAvailableEncodingList::const_iterator iter;
for (iter = RWUAvailableEncodingList::begin();
iter != RWUAvailableEncodingList::end();
++iter)
{
std::cout << *iter << std::endl;
}
// Iterate over the list of encodings again, obtaining
// iterators from an RWUAvailableEncodingList object.
RWUAvailableEncodingList list;
for (iter = list.begin(); iter != list.end(); ++iter) {
std::cout << *iter << std::endl;
}
return 0;
}

Global Operators
RWUAvailableEncodingListIterator
operator+(
RWUAvailableEncodingListIterator::difference_type offset,
const RWUAvailableEncodingListIterator& rhs);
Returns a new iterator whose list position is calculated by adding offset to the position of rhs. If the position of the new iterator is less than the position given by RWUAvailableEncodingList::begin(), the iterator is positioned at begin(). If the position of the new iterator is greater than the position given by RWUAvailableEncodingList::end(), the iterator is positioned at end().
RWUAvailableEncodingListIterator
operator+(const RWUAvailableEncodingListIterator& lhs,
RWUAvailableEncodingListIterator::difference_type offset);
Returns a new iterator whose list position is calculated by adding offset to the position of lhs. If the position of the new iterator is less than the position given by RWUAvailableEncodingList::begin(), the iterator is positioned at begin(). If the position of the new iterator is greater than the position given by RWUAvailableEncodingList::end(), the iterator is positioned at end().
RWUAvailableEncodingListIterator
operator-(const RWUAvailableEncodingListIterator& lhs,
RWUAvailableEncodingListIterator::difference_type offset);
Returns a new iterator whose list position is calculated by subtracting offset from the position of lhs. If the position of the new iterator is less than the position given by RWUAvailableEncodingList::begin(), the iterator is positioned at begin(). If the position of the new iterator is greater than the position given by RWUAvailableEncodingList::end(), the iterator is positioned at end().
Public Constructors
RWUAvailableEncodingListIterator(void);
Default constructor. Creates an invalid iterator. Attempts to dereference an invalid iterator throw RWBoundsErr. Use RWUAvailableEncodingList to obtain valid iterators.
RWUAvailableEncodingListIterator( const RWUAvailableEncodingListIterator& source);
Copy constructor. Makes self a copy of source.
Public Destructor
~RWUAvailableEncodingListIterator();
Destructor.
Public Member Operators
RWUAvailableEncodingListIterator& operator=(const RWUAvailableEncodingListIterator& rhs);
Changes the state of self to match that of rhs. Makes the list position of self equal to the list position of rhs.
bool operator==(const RWUAvailableEncodingListIterator& rhs) const;
Returns true if the list position of self is equal to the list position of rhs; otherwise, false.
bool operator!=(const RWUAvailableEncodingListIterator& rhs) const;
Returns true if the list position of self is not equal to the list position of rhs; otherwise, false.
bool operator<(const RWUAvailableEncodingListIterator& rhs) const;
Returns true if the list position of self is less than the list position of rhs; otherwise, false.
bool operator<=(const RWUAvailableEncodingListIterator& rhs) const;
Returns true if the list position of self is less than or equal to the list position of rhs; otherwise, false.
bool operator>(const RWUAvailableEncodingListIterator& rhs) const;
Returns true if the list position of self is greater than the list position of rhs; otherwise, false.
bool operator>=(const RWUAvailableEncodingListIterator& rhs) const;
Returns true if the list position of self is greater than or equal to the list position of rhs; otherwise, false.
value_type operator*() const;
Returns a const char* to a null-terminated character string containing the encoding name located at the list position specified by self.
The storage for this string is owned by the library.
Throws RWBoundsErr if the iterator is invalid or positioned past the end of the list.
RWUAvailableEncodingListIterator& operator++();
Repositions self to the next position in the encoding name list, and returns a reference to self. If self is equal to RWUAvailableEncodingList::end(), its position is left unchanged.
RWUAvailableEncodingListIterator operator++(int);
Repositions self to the next position in the encoding name list, and returns a new iterator that points to the old position. If self is equal to RWUAvailableEncodingList::end(), its position is left unchanged.
RWUAvailableEncodingListIterator& operator+=(difference_type offset);
Repositions self to a new position in the encoding name list by adding offset to the current iterator position, and returns a reference to self.
If the new position is less than the position given by RWUAvailableEncodingList::begin(), self is positioned at begin(). If the new position is greater than the position given by RWUAvailableEncodingList::end(), self is positioned at end().
RWUAvailableEncodingListIterator& operator--();
Repositions self to the previous position in the encoding name list, and returns a reference to self. If self is equal to RWUAvailableEncodingList::begin(), its position is left unchanged.
RWUAvailableEncodingListIterator operator--(int);
Repositions self to the previous position in the encoding name list, and returns a new iterator that points to the old position. If self is equal to RWUAvailableEncodingList::begin(), its position is left unchanged.
RWUAvailableEncodingListIterator& operator-=(difference_type offset);
Repositions self to a new position in the encoding name list by subtracting offset from the current iterator position, and returns a reference to self.
If the new position is less than the position given by RWUAvailableEncodingList::begin(), self is positioned at begin(). If the new position is greater than the position given by RWUAvailableEncodingList::end(), self is positioned at end().
difference_type operator-(const RWUAvailableEncodingListIterator& rhs) const;
Calculates the difference, or distance, between self and rhs.
