public class DelegatingFileSystemOptionsBuilder
extends Object

This class use reflection to set a configuration value using the fileSystemConfigBuilder associated the a scheme.

 FileSystemOptions fso = new FileSystemOptions();
 DelegatingFileSystemOptionsBuilder delegate = new DelegatingFileSystemOptionsBuilder(VFS.getManager());
 delegate.setConfigString(fso, "sftp", "identities", "c:/tmp/test.ident");
 delegate.setConfigString(fso, "http", "proxyPort", "8080");
 delegate.setConfigClass(fso, "sftp", "userinfo", TrustEveryoneUserInfo.class);
