AnnotationLister

public class AnnotationLister extends Object
Greps annotations on a set of class files and prints matching elements to stdout. What counts as a match and what should be printed is controlled by the {@code Main.Arguments} instance.

Fields Summary
private static final String
PACKAGE_INFO
The string name of the pseudo-class that contains package-wide annotations
private final Main.Arguments
args
current match configuration
HashSet
matchInnerClassesOf
Set of classes whose inner classes should be considered matched
HashSet
matchPackages
set of packages whose classes should be considered matched
Constructors Summary
AnnotationLister(Main.Arguments args)


       
        this.args = args;
Methods Summary
private booleanisMatchingInnerClass(java.lang.String s)
Checks to see if a specified class name should be considered a match due to previous matches.

param
s {@code non-null;} class name
return
true if this class should be considered a match

        int i;

            }
        }

        return false;
private booleanisMatchingPackage(java.lang.String s)
Checks to see if a specified package should be considered a match due to previous matches.

param
s {@code non-null;} package name
return
true if this package should be considered a match
