Interface ThreadContextClassLoaderHolder

public interface ThreadContextClassLoaderHolder

Specification for how to restore the original ThreadContext ClassLoader to a Thread. When we support JDK 1.7, this should really be an extension of AutoCloseable instead, to support the try-with-resources pattern. Typical use:

     
         // Create and set the ThreadContext ClassLoader
         ThreadContextClassLoaderHolder holder = null;

         try {

          holder = ThreadContextClassLoaderBuilder.createFor(getClass())
              .addPath("some/path")
              .addURL(someURL)
              .addPaths(aPathList)
              .buildAndSet();

          // ... perform operations using the newly set ThreadContext ClassLoader...

         } finally {
          // Restore the original ClassLoader
          holder.restoreClassLoaderAndReleaseThread();
         }
