Heap Walker View Settings Dialog

## 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 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.

| 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 Biggest objects tab applies to the biggest objects view only. Size scale You can select a 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 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.

| The References tab applies to the references view only. Size scale You can select a 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. 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. Instance block size The reference view only show a capped number of instances. This cap which is configurable here, has a default value of 100. Note that you can easily add more objects with the hyperlinks at the bottom of the reference tables.

| The Time tab applies to the time view only. It is analogous to the VM telemetry view settings dialog.

| The Graph tab applies to the graph only. 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. Warning threshold for opening references If an object has a lot of incoming or outgoing references, the graph can be visually overwhelmed with new objects. That's why JProfiler asks you if you really want to open a large number of references. The default threshold which is configurable here is set to 100.
