java.lang.Object org.codehaus.groovy.control.ClassNodeResolver
public class ClassNodeResolver extends Object
This class is used as a plugable way to resolve class names. An instance of this class has to be added to CompilationUnit using CompilationUnit.setClassNodeResolver. The CompilationUnit will then set the resolver on the ResolveVisitor each time new. The ResolveVisitor will prepare name lookup and then finally ask the resolver if the class exists. This resolver then can return either a SourceUnit or a ClassNode. In case of a SourceUnit the compiler is notified that a new source is to be added to the compilation queue. In case of a ClassNode no further action than the resolving is done. The lookup result is stored in the helper class LookupResult. This class provides a class cache to cache lookups. If you don't want this, you have to override the methods ClassNodeResolver.cacheClass and ClassNodeResolver.getFromClassCache. Custom lookup logic is supposed to go into the method ClassNodeResolver.findClassNode while the entry method is ClassNodeResolver.resolveName
