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