public interface ClassFileSource
ClassFileSource
allows you to override CFR's sourcing of byte code.
You could even generate bytecode on the fly and provide it to CFR.
If you wish to delegate to a 'normal' ClassFileSource
, you may get one from ClassFileSource.Factory
Note that implementations of this object that provide more than one class are likely to have to be
mutable, as they need to keep track of the relationship between classes and directories.Modifier and Type | Interface and Description |

Collection<String> |
addJar(String jarPath)
CFR would like to know about all classes contained within the jar at
jarPath |
Pair<byte[],String> |
getClassFileContent(String path)
Given a path to a class file, return a pair of
* the content, as a byte array.
|
String |
getPossiblyRenamedPath(String path)
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.

void |
informAnalysisRelativePathDetail(String usePath,
String classFilePath)
CFR has loaded your class, and it has decided that if it were in the correct location, it would instead
be at
classFilePath . |
void informAnalysisRelativePathDetail(String usePath, String classFilePath)
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.usePath
