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