RWGSlistIterator(type)

Data Type and Member Function Indexes
(exclusive of constructors and destructors)

Synopsis

#include <rw/gslist.h>
declare(RWGSlist, type)

RWGSlist(type) a ;
RWGSlistIterator(type) I(a);

Description

Iterator for class RWGSlist(type), which allows sequential access to all the elements of a singly-linked list. Elements are accessed in order, first to last.

As with all Rogue Wave 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Once the iterator has advanced beyond the end of the collection it is no longer valid -- continuing to use it will bring undefined results.

In order to simplify the documentation below, an imaginary typedef

typedef RWBoolean (*yourTester)(const type*, const void*);

has been used. See the documentation for class RWGSlist(type) for an explanation of this function.

Persistence

None
