| Env | | public class Env implements Iterable<Env<A>>(Code) | | A class for environments, instances of which are passed as
arguments to tree visitors. Environments refer to important ancestors
of the subtree that's currently visited, such as the enclosing method,
the enclosing class, or the enclosing toplevel node. They also contain
a generic component, represented as a type parameter, to carry further
information specific to individual passes.
This is NOT part of any API supported by Sun Microsystems. If
you write code that depends on this, you do so at your own risk.
This code and its internal interfaces are subject to change or
