Anchor Region

In order to start the analysis of a structured memory snapshot (page 343) a debugger engine needs Anchor Region that describes memory layout and where to start unfolding of analysis. For example, it can be a list of modules (another forthcoming structural pattern). We can observe the importance of such regions when we try to open corrupt or severely truncated memory dumps (Volume 2, page 151):
