    • connect

      public void connect(String host, int port, QualifiedUsername proxyUser, QualifiedUsername clientUser) throws Exception
      Connects to an iRODS server. The connection will represent a proxied connection. The proxy user provides the connection to the server.

This operation only establishes a connection. No authentication is performed.
      Parameters:
      host - The hostname or IP address of the iRODS server.
      port - The port number of the iRODS server.
      proxyUser - The iRODS user acting as the proxy.
      clientUser - The iRODS user being proxied.
      Throws:
      IllegalArgumentException - If any of the constructor requirements is violated.
