Inherited by WvList< T >::Iter.
Collaboration diagram for WvListBase::IterBase:
For internal use only.
The untyped base class of WvList<T>::Iter.
Putting common code in here allows us to prevent it from being replicated by each template instantiation of WvList<T>.

Public Member Functions | |
IterBase (const WvListBase &l) | |
Binds the iterator to the specified list. | |
void | rewind () |
Rewinds the iterator to make it point to an imaginary element preceeding the first element of the list. | |
WvLink * | next () |
Moves the iterator along the list to point to the next element. | |
WvLink * | cur () const |
Returns a pointer to the WvLink at the iterator's current location. | |
void * | vptr () const |
Returns a void pointer to the object at the iterator's current location. | |
WvLink * | find (const void *data) |
Rewinds the iterator and repositions it over the element that matches the specified value. | |

Binds the iterator to the specified list. "l" is the list Definition at line 82 of file wvlinklist.h. |
|
Returns a pointer to the WvLink at the iterator's current location. Returns: the current WvLink pointer, or null if there were no more elements remaining in the traversal sequence Definition at line 110 of file wvlinklist.h. Referenced by WvHashTableBase::prevlink(). |
|
Rewinds the iterator and repositions it over the element that matches the specified value. Uses pointer equality (object identity) as the criteria for finding the matching element. It is not possible to use find(const void*) to locate multiple matching elements unless the list is altered between invocations since it always starts searching from the head of the list rather than from the current location. Returns: the current WvLink pointer, or null if no such element was found Definition at line 58 of file wvlinklist.cc. References WvLink::data, link, next(), and rewind(). |
|
Moves the iterator along the list to point to the next element. If the iterator had just been rewound, it now points to the first element of the list. Returns: the current WvLink pointer, or null if there were no more elements remaining in the traversal sequence Definition at line 102 of file wvlinklist.h. References WvLink::next. Referenced by find(), and WvHashTableBase::prevlink(). |

Returns a void pointer to the object at the iterator's current location. You should almost never need this. Use ptr() instead. Definition at line 117 of file wvlinklist.h. References WvLink::data. |
