Examples of org.jruby.runtime.scope.ManyVarsDynamicScope

org.jruby.runtime.scope.ManyVarsDynamicScope
Represents the the dynamic portion of scoping information. The variableValues are the values of assigned local or block variables. The staticScope identifies which sort of scope this is (block or local). Properties of Dynamic Scopes: 1. static and dynamic scopes have the same number of names to values 2. size of variables (and thus names) is determined during parsing. So those structured do not need to change FIXME: When creating dynamic scopes we sometimes accidentally pass in extra parents. This is harmless (other than wasting memory), but we should not do that. We can fix this in two ways: 1. Fix all callers 2. Check parent that is passed in and make if new instance is local, then its parent is not local

            DynamicScope parent = dynamicScope.getNextCapturedScope();
            if (parent != null && parent.getEvalScope(runtime) == dynamicScope) {
                evalScope[0] = dynamicScope;
            } else {
                // bindings scopes must always be ManyVars scopes since evals can grow them
                evalScope[0] = new ManyVarsDynamicScope(runtime.getStaticScopeFactory().newEvalScope(dynamicScope.getStaticScope()), dynamicScope);
            }
        }


        return evalScope[0];
