The heap walker view settings dialog is accessed by bringing
the
heap walker to front
and choosing
View->View settings from JProfiler's main menu or clicking on
the corresponding toolbar button.
The context menu also gives access to the view settings dialog.
The General tab of the view settings dialog controls aspects which
apply to all heap walker views.
Show selection steps
If checked, the selection history window at the bottom of the heap walker is
shown.
Show view helper dialog for new object sets
If checked,
the view helper dialog
will be displayed when a new object set is created.
Note: Unlike for the allocation call tree, there is no "cumulate allocations"
option since the view mode combo box in the allocations view of the heap walker offers both an
"allocation tree" and a "cumulated allocation tree".
Show object IDs
If checked, all objects are annotated with object IDs. This can help you to check if an object is
the same as one displayed in another view.
Show retained size bar for dominator tree
If checked, a percentage bar will be shown in from of each outgoing reference node. The percentage
base can be configured as
Top level object
The percentages refer to the retained size of the top level object. This is
the default setting.
Total heap
The percentages show how much of the total heap is retained by this reference.
The lengths of all percentage bars are always comparable with this option.
Show object IDs
If checked, all objects are annotated with object IDs. This can help you in checking if two objects
in two different reference graphs are the same or not. There
are two separate options for the reference graph and the reference tree views since the
object IDs are much more important for the tree views where this option is enabled by default.
Show declaring class if different from actual class
In the incoming and outgoing reference tree views, the declaring class of a field will be displayed
as well if it is different from the actual class or the object (i.e. the field has been declared in a super-class).
Since this can add a lot of potentially distracting information to the reference trees, you can switch it
off with this setting. In the reference graph, the declaring class is always displayed in the tool tip on the
reference arrows.
