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.
Timeout for long operations
Computationally expensive operations, like sorting or calculating the path to root can take a
very long time, depending on the size of the heap. To avoid blocking the user interface, these
operations time out and return with partial results. If a timeout occurs, you are notified and
the amount of work done in percent is reported. The default timeout is 30 seconds, you can increase
it as needed.
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 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.
