   5 # This is a generic rule-tree for classifying native heaps on Android. It is a
   6 # simple hierarchical python data structure (list of dictionaries). Some rules:
   7 # - Order matters: what is caught by a node is not caught by its siblings.
   8 # - Hierarchy matters: what is caught by a node is propagated to its children
   9 #   (if any). Only one of its children, though, will get the data.
  10 # - Non leaf nodes have an extra implicit node called {node-name}-other: if
  11 #   something is caught by a non leaf node, but none of its children, it is
  12 #   appended to implicit {node-name}-other catch-all children.
  13 #
  14 # See memory_inspector/classification/native_heap_classifier.py for more docs.

  16 # TODO(primiano): This is just a quick sample. Enrich looking at DMP.
