Method Details

extractClassNames

public static Collection<String> extractClassNames(InputStream in)
                                            throws IOException

Delivers a list of all class names which are referred in the input.

Parameters:

in - the class data conformant to a valid class file as defined by The Java™ Virtual Machine Specification.

Throws:

IOException

findClasses

public static Collection<String> findClasses(@Opt
 @Opt String targetClassPath,
 @Opt
 @Opt Predicate<? super String> filter,
 @Opt
 @Opt BiConsumer<String,Exception> signalLoadingError,
 String... roots)

Find all recursive static references to classes.

Parameters:

targetClassPath - the class path to use for loading the referenced classes, or null for the system class path.

filter - a predicate to filter the class references. References to classes that are not accepted by this predicate are not loaded or traversed. The predicate null accepts anything.

signalLoadingError - when given, signalLoadingError receives class name and exception on trying to load the code of that class

roots - references to classes to start with, given as binary names.

unpackArrayTypes

public static Collection<String> unpackArrayTypes(Collection<String> types)
