Purify uses the following categories to highlight significant or interesting objects in the Object Reference Graph.
This criterion |
Highlights |
Top 10: Size |
The top ten objects by size |
Top 10: O+R Size |
The top ten objects by object + references (O+R) size |
Top 10: GCs Survived |
The top ten objects by number of garbage collections survived |
Top 10: Creation Time |
The top ten objects by creation time |
Top 10: References |
The top ten objects by number of immediate references to other objects |
Top 10: Referees |
The top ten objects by number of immediate referees |
Object: All References |
All objects in the reference tree, that are descended the selected object |
Object: Immediate References |
All immediate objects referenced by the selected object |
Object: All Referees |
All objects in the reference tree between .Root. and the selected object |
Object: Immediate Referees |
All immediate referees to the selected object |
Object: Maximum Path to Root |
The path of objects with the largest O+R size from the selected object to .Root. |
Objects with Source |
Objects that were allocated in methods for which source code is available. |
Notes:
§ To clear the current highlighting, select None.
§ The Object Reference Graph is not available for Diff runs.
§ You cannot open the Object Detail window for objects whose Root Type is Unreachable.
§ Purify does not automatically calculate object + references (O+R) size for the data views after a memory profiling run. To have Purify calculate O+R size for all objects, in the Object Reference Graph, right-click a node and select Line Scale Factors > Linear or Logarithmic from the shortcut menu.
