The contents of the allocation tree map is an alternate visualization of the
allocation tree.
The tree map shows all call stacks as a set of nested rectangles.
Please see the help on tree maps for more information.
The heap walker will be able to display allocation information only for recorded objects,
unrecorded objects are summed up in a top-level rectangle called unrecorded objects.
See the memory section overview
for further details.
To add a selection step from this view you can select one or multiple allocation spots
in the tree map and
click the [Use selected] button above the tree map.
A new object set will be created that contains all instances of classes and arrays
allocated in the selected allocation spots. After your selection,
the view helper dialog will
assist you in choosing the appropriate view for the new object set.
