Quick info view
"Quick Info" view shows useful information about selected object(s) and is available:
-
as a dependent view
- as a popup window invoked with Memory | Quick Info (Ctrl+Q) action.
The view shows retained and shallow size and object count for the current selection:
If a single object is selected, its generation is shown. If allocation trace is available, it is shown as well.
For a byte array "Quick info" shows its text representation in specified encoding (the snapshot must contain primitive values):
