Constructor Detail

FTPActiveDataSocket

protected FTPActiveDataSocket(java.net.ServerSocket sock)

Constructor

Parameters:

sock - the server socket to use

Method Detail

setTimeout

public void setTimeout(int millis)
                throws java.io.IOException

Set the TCP timeout on the underlying data socket(s). If a timeout is set, then any operation which takes longer than the timeout value will be killed with a java.io.InterruptedException.

setTimeout in interface FTPDataSocket

Parameters:

millis - The length of the timeout, in milliseconds

Throws:

java.io.IOException

getLocalPort

public int getLocalPort()

Returns the local port to which this socket is bound.

Specified by:

getLocalPort in interface FTPDataSocket

Returns:

the local port number to which this socket is bound

acceptConnection

protected void acceptConnection()
                         throws java.io.IOException

Waits for a connection from the server and then sets the timeout when the connection is made.

                                     throws java.io.IOException

If active mode, accepts the FTP server's connection - in PASV, we are already connected. Then gets the output stream of the connection

Specified by:

getOutputStream in interface FTPDataSocket

Returns:

output stream for underlying socket.

Throws:

java.io.IOException

getInputStream

public java.io.InputStream getInputStream()
                                   throws java.io.IOException

If active mode, accepts the FTP server's connection - in PASV, we are already connected. Then gets the input stream of the connection

Specified by:

getInputStream in interface FTPDataSocket

Returns:

input stream for underlying socket.

Throws:

java.io.IOException

close
