public class TFTPClient extends TFTP
Details regarding the TFTP protocol and the format of TFTP packets can be found in RFC 783. But the point of these classes is to keep you from having to worry about the internals.

int | getMaxTimeouts()
Returns the maximum number of times a receive attempt is allowed to
timeout before ending attempts to retry the receive and failing.

int | receiveFile(String filename, int mode, OutputStream output, InetAddress host, int port)
Requests a named file from a remote host, writes the
file to an OutputStream, closes the connection, and returns the number
of bytes read. |
int | receiveFile(String filename, int mode, OutputStream output, String hostname, int port)
Requests a named file from a remote host, writes the
file to an OutputStream, closes the connection, and returns the number
of bytes read. |
int | receiveFile(String filename, int mode, OutputStream output, InetAddress host)
Same as calling receiveFile(filename, mode, output, host, TFTP.DEFAULT_PORT).
|
int | receiveFile(String filename, int mode, OutputStream output, String hostname)
Same as calling receiveFile(filename, mode, output, hostname, TFTP.DEFAULT_PORT).
|
void | sendFile(String filename, int mode, InputStream input, InetAddress host, int port)
Requests to send a file to a remote host, reads the file from an
InputStream, sends the file to the remote host, and closes the
connection. |
void | sendFile(String filename, int mode, InputStream input, String hostname, int port)
Requests to send a file to a remote host, reads the file from an
InputStream, sends the file to the remote host, and closes the
connection. |
void | sendFile(String filename, int mode, InputStream input, InetAddress host)
Same as calling sendFile(filename, mode, input, host, TFTP.DEFAULT_PORT).
|
void | sendFile(String filename, int mode, InputStream input, String hostname)
Same as calling sendFile(filename, mode, input, hostname, TFTP.DEFAULT_PORT).
|
void | setMaxTimeouts(int numTimeouts)
Sets the maximum number of times a receive attempt is allowed to
timeout during a receiveFile() or sendFile() operation before ending
attempts to retry the receive and failing.

Returns: The maximum number of timeouts allowed.
