Details
When the heap is large with many objects, refreshing the snapshot will affect system performance more than refreshing from a smaller heap with fewer objects.
Sort by any of the data types by clicking the column heading in the Current Live Heap Objects table. Continue clicking on the same column heading to toggle the sort between ascending and descending order for numerical columns and by alphabetical order for columns containing text.
You can copy all or part of the data displayed into a temporary buffer, then paste or append it into a spreadsheet or other similar software using a keyboard shortcut.
To select a portion of the data, click and drag the cursor across the desired rows and columns of data. The selected rows change color. Then click Copy Selection to Buffer in the tool bar to capture the data.
