Generic Term Traversal Operators
Stratego -- Strategies for Program Transformation
Generic term traversal operators support te definition of
Generic term traversal strategies like
topdown
and
bottomup
. Operators available in Stratego are:
-
one
applies a strategy to one direct subterm.
-
some
applies a strategy to as much as possible, but a least one, direct subterms.
-
all
applies a strategy to all direct subterms of the subject term.
The generic term traversal operators are built-in: they are not defined in Stratego itself. It is however possible to define them in Stratego with even more primitive strategies.
