## Interface RMIClientSocketFactory

- All Known Implementing Classes:
    RMISocketFactory, SslRMIClientSocketFactory

      public interface RMIClientSocketFactory

  An `RMIClientSocketFactory` instance is used by the RMI runtime in order to obtain client sockets for RMI calls. A remote object can be associated with an `RMIClientSocketFactory` when it is created/exported via the constructors or `exportObject` methods of `java.rmi.server.UnicastRemoteObject` and `java.rmi.activation.Activatable` .

  An `RMIClientSocketFactory` instance associated with a remote object will be downloaded to clients when the remote object's reference is transmitted in an RMI call. This `RMIClientSocketFactory` will be used to create connections to the remote object for remote method calls.

  An `RMIClientSocketFactory` instance can also be associated with a remote object registry so that clients can use custom socket communication with a remote object registry.

  An implementation of this interface should be serializable and should implement `Object.equals(java.lang.Object)` to return `true` when passed an instance that represents the same (functionally equivalent) client socket factory, and `false` otherwise (and it should also implement `Object.hashCode()` consistently with its `Object.equals` implementation).
