Detailed Description

Iterate through those areas that have something assigned to them.

An iterator that iterates through all and only those areas which have resources assigned to them. Like the other iterators, it uses accessor functions defined in Allocatn.h and implemented in each allocation class.

Constructor & Destructor Documentation

ActiveAreasIterator::ActiveAreasIterator (  const Allocation &  p_allocation  )

From an allocation create an object to iterate over assigned (active) areas. Constructor that takes an allocation (could be any sub type) and then allows the user to iterates over ONLY the areas which have any resources assigned to them. (And all of those.) The new object begins with the first active area in this allocation. NOTE: Unlike the other iterators, this one only returns the area number WARNING: Does not check to make sure it got passed a proper allocation. Author : Michael Eldridge Rewritten: Andre Oboler (ASO)

ActiveAreasIterator::~ActiveAreasIterator (   )

Destructor: clean up memory allocated in "current". Author: Charles Twardy 18apr03, for bug spotted by GT.
