Creates a DefaultFileHandler.

Method Detail

getTransmitTextFilePreprocessor

public TransmitTextFilePreprocessor getTransmitTextFilePreprocessor()

Returns the preprocessor for transmitting text files.

setTransmitTextFilePreprocessor

public void setTransmitTextFilePreprocessor(TransmitTextFilePreprocessor transmitTextFilePreprocessor)

Sets the preprocessor for transmitting text files. The default one changes all line endings to Unix-lineendings (cvs default).

public WriteTextFilePreprocessor getWriteTextFilePreprocessor()

Gets the preprocessor for writing text files after getting (and un-gzipping) from server.

setWriteTextFilePreprocessor

public void setWriteTextFilePreprocessor(WriteTextFilePreprocessor writeTextFilePreprocessor)

Sets the preprocessor for writing text files after getting (and un-gzipping) from server.

getWriteRcsDiffFilePreprocessor

public WriteTextFilePreprocessor getWriteRcsDiffFilePreprocessor()

Gets the preprocessor for merging text files after getting (and un-gzipping) the diff received from server.

setWriteRcsDiffFilePreprocessor

public void setWriteRcsDiffFilePreprocessor(WriteTextFilePreprocessor writeRcsDiffFilePreprocessor)

Sets the preprocessor for merging text files after getting (and un-gzipping) the diff received from server.

Specified by:

getInitialisationRequests in interface FileHandler

Returns:

an array of Requests that must be sent

transmitTextFile
