|
|
||||||
* The method first gets the current ClassLoader. It then fetches all resources
|
|
||||||
* that contain said package and iterates of these URLs. It then creates a
|
|
||||||
* URLConnection and determines what type of URL we have. It can either be a
|
|
||||||
* directory (FileURLConnection) or a directory inside a jar or zip file
|
|
||||||
* (JarURLConnection). Depending on what type of connection we have two
|
|
||||||
* different methods will be called.
|
|
||||||
*
|
|
||||||
* First lets see what happens if it is a FileURLConnection.
|
|
||||||
*
|
|
||||||
* It first checks if the passed File exists and is a directory. If that's the
|
|
||||||
* case it checks if it is a class file. If so a Class object will be created
|
|
||||||
* and put in the List. If it is not a class file but is a directory, we
|
|
||||||
* simply iterate into it and do the same thing. All other cases/files will be
|
|
||||||
* ignored.
|
|
||||||
*
|
|
||||||
* If the URLConnection is a JarURLConnection the other private helper method
|
|
||||||
* will be called. This method iterates over all Entries in the zip/jar
|
|
||||||
* archive. If one entry is a class file and is inside of the package a Class
|
|
||||||
* object will be created and stored in the ArrayList.
|
|
||||||
*
|
|
||||||
* After all resources have been parsed it (the main method) returns the
|
|
||||||
* ArrayList containing all classes in the given package, that the current
|
|
||||||
* ClassLoader knows about.
|
|
||||||
*
|
|
||||||
* If the process fails at any point a ClassNotFoundException will be thrown
|
|
||||||
* containing detailed information about the exact cause.
