Heap Walker View Settings Dialog

     


  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.
  The Classes tab applies to the classes view only. It is analogous to the recorded objects view settings.
  The Allocations tab applies to the allocation view only. It is analogous to the allocation call tree settings.

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".

  The References tab applies to the references view only.
  • Size scale
    You can select size scale, just like in the recorded object view settings.
  • 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.
  The Time tab applies to the time view only. It is analogous to the VM telemetry view settings dialog.
