The Action Point > At Location dialog box lets you set breakpoints on all functions within a class or on a virtual function. The All Methods in Class and All Virtual Functions and Overrides sets a breakpoint that covers multiple source lines and functions. That is, the breakpoint has multiple address blocks covering all of the locations matching the breakpoint expression.

TotalView tells you that the action point is set on a virtual function or a class in the Action Points tab. If you dive on the action point in this tab, TotalView brings up its Ambiguous Line dialog box so that you can select which source line it should display. You may want to select the Show full path names check box if you can’t tell which you want from the function’s signature.

If a function name is overloaded, the debugger sets a breakpoint on each of these functions.

If you want the breakpoint to stop in only some functions, use the Action Point Properties dialog, accessed either by right-clicking on the breakpoint and clicking Properties or by selecting the Action Point > Properties command, and then clicking Addresses to open the Action Point Addresses dialog.

You can now enable or disable individual address blocks within the breakpoint. Initially, addresses are either enabled or disabled, but you can change their state by clicking the checkbox in the first column. The checkbox in the columns bar enables or disables all the addresses. This dialog supports selecting multiple separate items (Ctrl-Click) or a range of items (Shift-Click or click and drag). Once the desired subset is selected, right-click one of the selected items and choose Enable Selection or Disable Selection from the context menu.

In complex programs that use many shared libraries, the number of addresses can become very large, so the Addresses dialog has several mechanisms to manage the data. The search box filters the currently displayed data based on one or more space-separated strings or phrases (enclosed in quotes). Remember that data not currently displayed is not included in the filtering. It may be helpful to click the Detailed Information checkbox, which displays much more complete symbol table information, giving you more possibilities for filtering.

Clicking on the column labels performs a sort based on the data in that column. Each click toggles between ascending and descending order. If entry values in a column are the same, the values of the column to the right of the sorted column are examined and sorted based on those values. If the values are the same, the next column is examined and so on, until different values are found. The Addresses dialog uses a stable sort, i.e. if all the entries are the same in the selected column and in the columns to the right, the list is not modified.

Finally, right-clicking in the columns bar presents a context menu for displaying or hiding columns. All are initially displayed except Image. You can reorder the columns by selecting a column label and dragging it to a new location.

To provide easy access to the buttons at the bottom of the Addresses dialog, the following mnemonic keys have been assigned.
