Visualizing the heap (Part 2)
Last week's tip described how you display the Memory Debugger's Graphical View. This week's tip looks at the information contained within this view.
The top area displays bars indicating allocated memory blocks. The block's coloring indicates the block's status. You can change the scale of what is displayed using the magnifying glass icons just above and to the right of the blocks.
When you select a block in the top area, the Memory Debugger looks up information on the block and displays information in the bottom area. While the block you selected is highlighted, the Memory Debugger also highlights other blocks created by code that had the same backtrace.
The bottom area can display information in two ways:
- Heap Information: the center pane displays information on the block that you selected, and the right pane displays information about all blocks that were created that have the same backtrace.
- Backtrace/Source: Contains two panes that display the backtrace that existed when the block was allocated and the line that caused the allocation to occur.
If you right-click your mouse on a block in the top portion, the Memory Debugger displays a menu containing a Properties command. If you select this command, the Memory Debugger both displays its Block Properties window, which contains more information about the block, and begins tracking this block for you. (Using the Block Properties Window will be discussed in a future tip.)
