#Java reflection javadoc code#
if your source code doesn't match the code you are executing, step 5 could fail.if your mapping are incomplete, step 4 could fail,.in step 3, the resulting URI could have a weird protocol,.in step 3, getCodeSource() could return null,.in step 2, you need to deal with nested classes,.Some of the above steps could present problems. Resolve the relative path relative to the root of the source tree.Map the URI to the corresponding source tree.
Use clazz.getProtectionDomain().getCodeSource().getLocation().toURI() to get the URI from whence the class was loaded.Map the classname to a relative Java source path e.g.Get the fully qualified class name from the Class object.a mapping from each URI to a corresponding source tree.the URIs for each JAR or directory on the classpath,.Let us assume that you have multiple source trees corresponding to multiple JARs on the application's classpath. The problem will be mapping from a Class object to the corresponding source code file. And if you have a source code file you should be able to extract comments using JavaParser or (possibly) some other library. The information is not present the ".class" file, and reflection only knows about information is directly available from there.Īs people have pointed out, you can only get comments if you have the source code. First of all, you cannot directly get comments using reflection, and you cannot get them by using a library that reads the ".class" file.
