The Object Reference Graph view shows the referential relationship of objects in a graph.
To open the Object Reference Graph view, right-click a profiling resource entry in the Profiling Monitor and select from the pop-up menu. .
Here
are some tips for using the graph:
- To scroll the contents of the graph, use the scroll bars, or click the background of the graph to display the hand cursor and then drag the cursor left, right, up, or down.
- To view details about a node or a path segment, pause the mouse cursor over the node or path segment.
The Object Reference Graph view can display the
following information when you pause your cursor over items in the graph:
The following icons indicate whether all
or only some objects referenced from an object are visible in the
graph:
The following controls and menu commands
appear in the Object Reference Graph view::
| Data item | Description |
|---|---|
| Object | The name of the object. If the object is ungrouped (a single instance of a Java™ class), the name is followed by an instance identifier. |
| Size | The size of the object, measured in bytes. If the object is grouped (all instances of a specific Java class), this number is a sum for all instances in the group. |
| References | The number of objects referenced by the selected object. If the object is grouped, this number is the sum for all instances in the group. |
| Referers | The number of objects that reference the selected object. If the object is grouped, this number is a sum for all instances in the group. |
| Count | For a grouped object, the number of instances in the group. The count for an ungrouped object is always 1. For a path segment, the number of references from the referencing (From) node to the referee (To) node. |
| From | For a path segment, the name of the referencing object. If the object is ungrouped (a single instance of a Java class), the name is followed by a instance identifier. |
| To | For a path segment, the name of the referee object. If the object is ungrouped (a single instance of a Java class), the name is followed by a instance identifier. |
| Propagated Memory | For a path segment, the Size of the referenced node. |
