Class TFTPAckPacket

java.lang.Object
org.apache.commons.net.tftp.TFTPPacket
org.apache.commons.net.tftp.TFTPAckPacket

public final class TFTPAckPacket extends TFTPPacket
A final class derived from TFTPPacket defining the TFTP Acknowledgement packet type.

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. Additionally, only very few people should have to care about any of the TFTPPacket classes or derived classes. Almost all users should only be concerned with the TFTPClient class receiveFile() and sendFile() methods.
