Visitor to resolve Types and convert VariableExpression to ClassExpressions if needed. The ResolveVisitor will try to find the Class for a ClassExpression and prints an error if it fails to do so. Constructions like C[], foo as C, (C) foo will force creation of a ClassExpression for C

Note

the method to start the resolving is startResolving(ClassNode, SourceUnit).

Nested and Inner Type Summary

Modifier and TypeClass and Description
private static class
ResolveVisitor.ConstructedClassWithPackage

we use ConstructedClassWithPackage to limit the resolving the compiler does when combining package names and class names.

private static class
ResolveVisitor.ConstructedNestedClass

A ConstructedNestedClass consists of an outer class and a name part, denoting a nested class with an unknown number of levels down.

private static class
ResolveVisitor.LowerCaseClass

we use LowerCaseClass to limit the resolving the compiler does for vanilla names starting with a lower case letter.
