Constructor:

Constructor:
public UnifiedClassLoader3(URL url) { this(url, null); } Construct a `UnifiedClassLoader` without registering it to the classloader repository. Parameters: `url` - the single URL to load classes from.
public UnifiedClassLoader3(URL url, URL origURL) { super(url, origURL); } Construct a `UnifiedClassLoader` without registering it to the classloader repository. Parameters: `url` - the single URL to load classes from. `origURL` - the possibly null original URL from which url may be a local copy or nested jar.
public UnifiedClassLoader3(URL url, URL origURL, LoaderRepository repository) { this(url, origURL); // set the repository reference this.setRepository(repository); } Construct a UnifiedClassLoader and associate it with the given repository. Parameters: `url` - The single URL to load classes from. `origURL` - the possibly null original URL from which url may be a local copy or nested jar. `repository` - the repository this classloader delegates to
public UnifiedClassLoader3(URL url, URL origURL, ClassLoader parent, LoaderRepository repository) { super(url, origURL, parent); // set the repository reference this.setRepository(repository); } Construct a UnifiedClassLoader and associate it with the given repository. Parameters: `url` - The single URL to load classes from. `origURL` - the possibly null original URL from which url may be a local copy or nested jar. `parent` - the parent class loader to use `repository` - the repository this classloader delegates to

 public UnifiedClassLoader3(URL url) {
      this(url, null);
}

    LoaderRepository repository) {
      this(url, origURL);
      // set the repository reference
      this.setRepository(repository);
}

 public UnifiedClassLoader3(URL url,
    URL origURL,
    ClassLoader parent,
    LoaderRepository repository) {
      super(url, origURL, parent);
      // set the repository reference
      this.setRepository(repository);
}
