Class ImportScannerImpl

java.lang.Object

spoon.reflect.visitor.CtScanner

spoon.reflect.visitor.ImportScannerImpl

All Implemented Interfaces:

CtVisitor, ImportScanner

public class ImportScannerImpl
extends CtScanner
implements ImportScanner

A scanner that calculates the imports for a given model. This class is not used anymore, it has been replaced by all subclasses of ImportAnalyzer. Still, we keep ImportScannerImpl for backward compatibility because it is used by some clients.
