Changing How Data is Displayed Figure 165: An Untransformed Map Figure 166: A Transformed Map Displaying STL Variables The C++ STL (Standard Template Library) greatly simplifies the way in which you can access data. Since it offers standard and prepackaged ways to organize data, you do not have to be concerned with the mechanics of the access method. The disadvantage to using the STL while debugging is that the information debuggers display is organized according to the compiler’s view of the data, rather than the STL’s logical view. For example, here is how your compiler sees a map compiled using the GNU C++ compiler (gcc): Most of the information is generated by the STL template and, in most cases, is not interesting. In addition, the STL does not aggregate the information in a useful way. STLView solves these problems by rearranging (that is, transforming) the data so that you can easily examine it. For example, here is the transformed map. Using native and GCC compilers on IBM AIX, IRIX/MIPS, HP Tru64 Alpha, and Sun Solaris, TotalView can transform STL strings, vectors, lists, and 280 Chapter 14: Examining and Changing Data
Figure 167: List and Vector Transformations Changing How Data is Displayed maps. TotalView can also transform these STL types if you are using GCC and Intel Version 7 and 8 C++ 32-bit compiler running on the Red Hat x86 platform. The TotalView Platforms and System Requirements Guide names the compilers for which TotalView transforms STL data types. The following figure shows an untransformed and transformed list and vector. You can create transformations for other STL containers. See the “TotalView Reference Guide” for more information. By default, TotalView transforms STL types. If you need to look at the untransformed data structures, clear the View simplified STL containers (and user-defined transformations) checkbox on the Options Page of the File > Preference Dialog Box.
