        public java.lang.String getPossiblyRenamedPath​(java.lang.String path)
        Description copied from interface: ClassFileSource
        It's possible that an obfuscator might have generated a bizarre and magic file inside a jar such that it's path is too big to read. Or it's invalid. This allows you to remap paths.

        getPossiblyRenamedPath in interface ClassFileSource
        Parameters:
        path - Path CFR would like to use
        Returns:
        Remapped path.

        Description copied from interface: ClassFileSource
        Given a path to a class file, return a pair of * the content, as a byte array. * the path where you found this.

        Pair<byte[], String> of class file content, and file location.
        Throws:

        Description copied from interface: ClassFileSource
        CFR has loaded your class, and it has decided that if it were in the correct location, it would instead be at classFilePath. This information should be taken into account when loading any inner classes, or other classes that CFR tries to load in order to improve decompilation. Why do you care? Let's say you have a class in a top level outside its normal structure, Bob.class. It should be found at org/person/Bob.class. Implementors of this will be called back with "", and "org/person", telling you that org.person are implicit in your path. CFR may later ask you to load "org/person/Bob$1.class". You should adjust this path to match where Bob$1 actually is. This will also be called with null, null to reset.
        Specified by:
        informAnalysisRelativePathDetail in interface ClassFileSource
        Parameters:
        usePath - the path that was used to load a class file.
        specPath - the path that CFR actually suspects it should have been, based on package name.
