# This is a generic rule-tree for classifying native heaps 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/native_heap_classifier.py for more docs.

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