RWFtpPwdReply is a specialization class of RWFtpReply. RWFtpPwdReply attempts to parse the FTP protocol reply for the current directory information. For instance, the following is a common type of server reply from the PWD
command:
In this reply, 257
is a standardized reply, as defined by the FTP RFC 959. However, the RFC does not include a standard syntax for returning the directory information in the text part of the message. RWFtpPwdReply examines RWNumReplyLine objects contained within self in a last-to-first order, searching for a quoted string. As soon as a match is found, a data member is set to the path. The path can be obtained with the getDirectory() member function.
Although most FTP servers follow this technique, it is not guaranteed because the directory information is returned in the reply text part of the protocol reply. For this reason, failure to parse the directory from the reply does not constitute an error. If the directory name cannot be parsed, the getDirectory() method simply returns an empty string.
RWFtpPwdReply::RWFtpPwdReply | ( | void | ) |
Default constructor.
RWFtpPwdReply::RWFtpPwdReply | ( | const RWFtpPwdReply & | reply | ) |
Copy constructor.
RWCString RWFtpPwdReply::getDirectory | ( | void | ) | const |
Returns the present working directory that is obtained by examining the reply text. See the Detailed Description section for this class. The RWCString should contain 7-bit US-ASCII data.
RWFtpPwdReply & RWFtpPwdReply::operator= | ( | const RWFtpPwdReply & | reply | ) |
Assignment operator. Makes self a copy of reply. The previous contents of self are lost.
|
protectedvirtual |
Provides an extended parse mechanism that can extract the directory path out of the reply text.
Reimplemented from RWNumReply.
|
friend |
Outputs an RWFtpPwdReply object to an std::ostream.
