Class ClassScreener

java.lang.Object
  extended by edu.umd.cs.findbugs.ClassScreener
All Implemented Interfaces:
IClassScreener

public class ClassScreener
extends java.lang.Object
implements IClassScreener

Class to pre-screen class files, so that only a subset are analyzed. This supports the -onlyAnalyze command line option. Modified February 2006 in four ways: a) don't break windows platform by hard-coding '/' as the directory separator b) store list of Matchers, not Patterns, so we don't keep instantiating Matchers c) fix suffix bug, so FooBar and Foo$Bar no longer match Bar d) addAllowedPackage() can now handle unicode chars in filenames, though we still may not be handling every case mentioned in section 7.2.1 of the JLS
