## Constructor Details

### RMIJRMPServerImpl

public RMIJRMPServerImpl(int port, RMIClientSocketFactory csf, RMIServerSocketFactory ssf, Map<String,?> env) throws IOException

Creates a new `RMIServer` object that will be exported on the given port using the given socket factories.

Parameters:
  `port` - the port on which this object and the `RMIConnectionImpl` objects it creates will be exported. Can be zero, to indicate any available port.
  `csf` - the client socket factory for the created RMI objects. Can be null.
  `ssf` - the server socket factory for the created RMI objects. Can be null.
  `env` - the environment map. Can be null.
Throws:
  `IOException` - if the `RMIServer` object cannot be created.
  `IllegalArgumentException` - if `port` is negative.

## Method Details

### export

protected void export() throws IOException
Description copied from class: `RMIServerImpl`

Exports this RMI object.

Specified by:
  `export` in class `RMIServerImpl`
Throws:
  `IOException` - if this RMI object cannot be exported.

### getProtocol

protected String getProtocol()
Description copied from class: `RMIServerImpl`

Returns the protocol string for this object. The string is `rmi` for RMI/JRMP.

Specified by:
  `getProtocol` in class `RMIServerImpl`
Returns:
  the protocol string for this object.

### toStub

public Remote toStub() throws IOException

Returns a serializable stub for this `RMIServer` object.

Specified by:
  `toStub` in class `RMIServerImpl`
Returns:
  a serializable stub.
Throws:
  `IOException` - if the stub cannot be obtained - e.g the RMIJRMPServerImpl has not been exported yet.

### makeClient

protected RMIConnection makeClient(String connectionId, Subject subject) throws IOException

Creates a new client connection as an RMI object exported through JRMP. The port and socket factories for the new `RMIConnection` object are the ones supplied to the `RMIJRMPServerImpl` constructor.

Specified by:
  `makeClient` in class `RMIServerImpl`
Parameters:
  `connectionId` - the ID of the new connection. Every connection opened by this connector server will have a different id. The behavior is unspecified if this parameter is null.
  `subject` - the authenticated subject. Can be null.
Returns:
  the newly-created `RMIConnection`.
Throws:
  `IOException` - if the new `RMIConnection` object cannot be created or exported.

### closeClient

protected void closeClient(RMIConnection client) throws IOException
Description copied from class: `RMIServerImpl`

Closes a client connection made by `makeClient`.

Specified by:
  `closeClient` in class `RMIServerImpl`
Parameters:
  `client` - a connection previously returned by `makeClient` on which the `closeClient` method has not previously been called. The behavior is unspecified if these conditions are violated, including the case where `client` is null.
Throws:
  `IOException` - if the client connection cannot be closed.

### closeServer

protected void closeServer() throws IOException

Called by `RMIServerImpl.close()` to close the connector server by unexporting this object. After returning from this method, the connector server must not accept any new connections.

Specified by:
  `closeServer` in class `RMIServerImpl`
Throws:
  `IOException` - if the attempt to close the connector server failed.
