- Tree Sharing Analysis
- Y. Orlarey, (c) Grame 2002
-------------------------------------------------------------------------------
-The sharing analysis of tree t is the annotation of all its subtrees t'
-with their number of occurences in t. As this annotation of t' depends of
-a context (the tree t for which t' is a subtree) a specific property key
-unique to each sharing analysis must be generated.
-
- API:
- ----
-
- shprkey(t) -> k = unique sharing property key of t
- shcount(k,t') -> n = returns the number of occurences of t' in t (where k = shprkey(t))
- shlysis(t) -> k = annotated the subtrees of t with prop (key sharing-count)
- (0 if t' is not a subtree of t)
-
- History :
- ---------
