Class ScopeManager

  • public class ScopeManager
extends java.lang.Object
    The scope manager builds a multitree-structure of scopes associated to a scope. These Scopes capture the are of validity of certain (Variable-, Field-, Record-)declarations but are also used to identify outer scopes that should be target of a jump (continue, break, throw).

    enterScope(Node) and leaveScope(Node) can be used to enter the Tree of scopes and then sitting at a path, access the currently valid "stack" of scopes.
