Method Detail

transmitTextFile

void transmitTextFile(File file,
                    LoggedDataOutputStream dos)
                      throws IOException

Transmit a text file to the server, using the standard CVS protocol conventions. CR/LFs are converted to the Unix format.

Parameters:

file - the file to transmit

dos - the data outputstream on which to transmit the file

Throws:

IOException

transmitBinaryFile

void transmitBinaryFile(File file,
                      LoggedDataOutputStream dos)
                        throws IOException

Transmit a binary file to the server, using the standard CVS protocol conventions.

Parameters:

file - the file to transmit

dos - the data outputstream on which to transmit the file

Throws:

IOException

writeTextFile

void writeTextFile(String path,
                 String mode,
                 LoggedDataInputStream dis,
                 int length)
                   throws IOException

Write (either create or replace) a text file on the local machine with one read from the server.

Parameters:

path - the absolute path of the file, (including the file name).

mode - the mode of the file

dis - the stream to read the file from, as bytes

length - the number of bytes to read

Throws:

IOException

writeRcsDiffFile

void writeRcsDiffFile(String path,
                    String mode,
                    LoggedDataInputStream dis,
                    int length)
                      throws IOException

Merge a text file on the local machine with the diff from the server. (it uses the RcsDiff response format - see cvsclient.ps for details)

Parameters:

path - the absolute path of the file, (including the file name).

mode - the mode of the file

dis - the stream to read the file from, as bytes

length - the number of bytes to read

Throws:

IOException

writeBinaryFile

void writeBinaryFile(String path,
                   String mode,
                   LoggedDataInputStream dis,
                   int length)
                     throws IOException

Write (either create or replace) a text file on the local machine with one read from the server.

Parameters:

path - the absolute path of the file, (including the file name).

mode - the mode of the file

dis - the stream to read the file from, as bytes

length - the number of bytes to read

Throws:

IOException

removeLocalFile

void removeLocalFile(String pathname)
                     throws IOException

Remove the specified file from the local disk. If the file does not exist, the operation does nothing.

Parameters:

pathname - the full path to the file to remove

Throws:

IOException - if an IO error occurs while removing the file

copyLocalFile

void copyLocalFile(String pathname,
                 String newName)
                   throws IOException

Copy a local file to new destination. If the destination file exists, the file is overwritten.

Parameters:

pathname - the full path to the file to copy

newName - the new name of the file's copy (not the full path)

Throws:

IOException - if an IO error occurs while copying the file

setNextFileDate

void setNextFileDate(Date modifiedDate)

Set the modified date of the next file to be written. The next call to writeFile will use this date.

Parameters:

modifiedDate - the date the file should be marked as modified

getInitialisationRequests

Request[] getInitialisationRequests()

Get any requests that must be sent before commands are sent, to init this file handler.

Returns:

an array of Requests that must be sent

setGlobalOptions

void setGlobalOptions(GlobalOptions globalOptions)

Sets the global options. This can be useful to detect, whether local files should be made read-only.
