eu.bandm.tools.d2d2.base.Resolver.ReferenceResolver

All Implemented Interfaces:

Rewriter

Enclosing class:

Resolver

protected class Resolver.ReferenceResolver
extends Rewrite

Here all declaration objects, all items and all imported modules are already rewritten. What really has to be re-written are the expressions which make the substitution value in an import-rewrite, plus those which are contained in the field .value of all XRegExp.
Visiting starts with the (externally requested) top-level module and follows the import statements.

FIXME -- BETTER: realize "#implicit" as an OPERATOR, then no special copy action would be necessary.

resolveRefText

protected Expression resolveRefText(Reference ref,
                                    Insertion callingInsertion)

Resolve the source text of a reference to a declaration and store this in "resolved".
First look, whether the name of the reference appears in a global or local substitution which comes with the import statement. (These have already been visited and resolved !?!)
Otherwise, set ".resolved" to an XRegExp/Enumeration (declaration) either in an imported module, or in the same module as the expression is. In case the ref is subjet to INSERTION, than a error is generated iff the rewriting does not go again to a reference. (NB The info about the error cause (i.e. the wrong re-writing) is only known here, NOT on the level of "action(Insertion)"! Therefore the resp. error message generation had to be dislocated to here!)

Parameters:

ref - the Reference to resolve

ins - the Insertion expression directly containing ref, or null.

action

public void action(Reference ref)

Overrides:

action in class Rewrite
