RWTValSlistIterator<T>
Synopsis #include <rw/tvslist.h>
RWTValSlist<T< list;
RWTValSlistIterator<T> iterator(list);
Description Iterator for class RWTValSlist<T> , allowing sequential access to all the
elements of a singly-linked parameterized list. Elements are accessed in order,
from first to last.
Like all Tools.h++ iterators, the "current item" is undefined immediately after
construction—you must define it by using operator() or some other (valid)
operation.
Once the iterator has advanced beyond the end of the collection it is no longer
valid—continuing to use it will bring undefined results.
Public constructor RWTValSlistIterator<T>(RWTValSlist<T>& c);
Constructs an iterator to be used with the list c .
Public member operators RWBoolean operator++();
Advances the iterator one position. Returns TRUE if the new position is valid,
FALSE otherwise.
RWBoolean operator+=(size_t n);
Advances the iterator n positions. Returns TRUE if the new position is valid,
FALSE otherwise.
RWBoolean operator()();
Advances the iterator one position. Returns TRUE if the new position is valid,
FALSE otherwise.
