Viewing a List of Variables
Figure 195: The Tools >
Expression List Window
Figure 196: Using Methods in
the Tools > Expression
List Window
The expressions in this window are:
i A variable with one value. The Value column shows its
value.
d1_array An aggregate variable; that is, an array, a structure, a
class, and so on. Its value cannot be displayed in one
line. Consequently, TotalView just gives you some information
about the variable. To see more information,
dive on the variable. After diving, TotalView displays the
variable in a Variable Window.
d1_array[1].d1_v
When you place an aggregate variable in the Expression
column, you need to dive on it to get more information.
An element in an array of structures. If TotalView can
resolve what you enter in the Expression column into a
single value, it displays a value in the Value column. If
TotalView can’t, it displays information in the same way
that it displays information in the d1_array example.
d1_array[i-1].d1_v
An element in an array of structures. This expression
differs from the previous example in that the array index
is an expression. Whenever execution stops in the
current thread, TotalView reevaluates the i-1 expression.
This means that TotalView might display the value
of a different array item every time execution stops.
The expressions you enter cannot include function calls.
You can also enter methods and functions within an Expression. Figure 196
shows two get methods and a get method used in an expression.
