• All heap walker views share the same basic layout:

  

• The description of the current object set shows
  • what kind of objects are in the current object set. If there is more than one class or array type in the current object set, a cumulative count will be given separately for class instances and arrays. As it is often the case, if all objects are of a single class or array type, the class name or array type will be displayed.
  • how many selection steps have occurred so far. This gives an idea of the complexity of the current selection.
  • how much space the current object set uses on the heap. Note that this is the shallow size which does not include the sizes of referenced arrays and class instances.

• With the selection button you can add another selection step. A new object set that contains only the currently selected objects will be created. Some views have other view specific controls in this area.

• The main portion of the view displays the content which depends on the current view type.

• The selection history shows all selection steps that have occurred so far. The selection history pane is a vertical split pane and can be resized to the most convenient size. You can toggle the visibility of the selection history window by
  • choosing Edit->Show selection steps from JProfiler's main menu
  • clicking on the corresponding toolbar button

• The view selector allows you to switch between the four different views without changing the current object set. The views show
  • the classes in the current object set
  • the allocation spots of the current object set
  • the references of the current object set
  • the class and instance data of the current object set
