Detailed Description

template<class T>
class PP_ListIterator< T >

Iterate over a List for ParmParse.

The class PP_ListIterator<T> is an iterator over class PP_List<T>.

This class does NOT provide a default constructor or an assignment operator.

This is a convenience class for ParmParse and will not be in any way supported by anyone at ANAG.

Constructor & Destructor Documentation

template<class T> PP_ListIterator< T >::PP_ListIterator (  const PP_List< T > &  aList  )  [inline]

: Construct a PP_ListIterator<T> to first element of aList.

template<class T> PP_ListIterator< T >::PP_ListIterator (  const PP_ListIterator< T > &  rhs  )  [inline]

: The copy constructor.

template<class T> PP_ListIterator< T >::PP_ListIterator (  const PP_List< T > &  _list, PP_ListLink< T > *  _p )  [inline, protected]

Member Function Documentation

template<class T> const T & PP_ListIterator< T >::operator * (   )  const [inline]

: Return a constant reference to the object in the PP_List<T> currently pointed to by this PP_ListIterator<T>.

template<class T> PP_ListIterator< T >::operator void * (   )  [inline]

: This is a conversion operator that makes the iterator look like a pointer. This operator makes it easy to check if the iterator is pointing to an element on the PP_List<T>. If the iterator has been moved off the PP_List<T> or if the PP_List<T> is empty, this conversion returns the NULL pointer.

template<class T> bool PP_ListIterator< T >::operator! (   )  const [inline]

: Returns true if PP_ListIterator<T> doesn't point to any element on the PP_List<T>.

template<class T> bool PP_ListIterator< T >::operator!= (  const PP_ListIterator< T > &   )  const [inline]

: Are the PP_ListIterator<T>s not equal?

template<class T> const T & PP_ListIterator< T >::operator() (   )  const [inline]

: Return a constant reference to the object in the PP_List<T> currently pointed to by this PP_ListIterator<T>.

template<class T> PP_ListIterator< T > PP_ListIterator< T >::operator++ (  int   )  [inline]

: This is the postfix auto-increment operator. It advances the PP_ListIterator<T> to point to the next element on the PP_List<T>. It then returns a PP_ListIterator<T> that points to the old element to allow for chaining with other operators.

template<class T> PP_ListIterator< T > & PP_ListIterator< T >::operator++ (   )  [inline]

: This is the prefix auto-increment operator. It advances the PP_ListIterator<T> to point to the next element on the PP_List<T>. It then returns a reference to itself to allow for chaining with other operators.

template<class T> PP_ListIterator< T > PP_ListIterator< T >::operator-- (  int   )  [inline]

: This is the postfix auto-decrement operator. It moves the PP_ListIterator<T> to point to the previous element on the PP_List<T>. It then returns a PP_ListIterator<T> that points to the old element to allow for chaining with other operators.

template<class T> PP_ListIterator< T > & PP_ListIterator< T >::operator-- (   )  [inline]

: This is the prefix auto-decrement operator. It moves the PP_ListIterator<T> to point to the previous element on the PP_List<T>. It then returns a reference to itself to allow for chaining with other operators.

template<class T> bool PP_ListIterator< T >::operator== (  const PP_ListIterator< T > &   )  const [inline]

: Do the two PP_ListIterator<T>s point to the same PP_List<T> and the same element within the PP_List<T>?

template<class T> void PP_ListIterator< T >::rewind (   )  [inline]

: Reset this PP_ListIterator<T> to point to the first element in the PP_List<T>.

template<class T> const T & PP_ListIterator< T >::value (   )  const [inline]

: Return a constant reference to the object in the PP_List<T> currently pointed to by the iterator.
