DtOutputLogger Class Reference

This is a simple class for logging information to a file. To be used, the caller must specify a logging level as well as a global logging level. If the threshold is < the globalThreshold, then the output logger will output the specified information to the associated file, if the file was created successfully.

Note

If the file already exists, it will be overwritten if writable. If the file cannot be opened, then no error is returned - output will just not be logged.

If the filename is reset at any point, then the currently open file is closed and a new file is opened with the specified name.

Note

The filename must not be an empty string.

bool DtOutputLogger::resetLog

(

)

Closes the log file and reopens it, overwriting the existing file.

)

const

Returns the name of the file currently being logged to.

bool DtOutputLogger::setFilename

(

const std::string &

newFilename

)

Closes the current log if any, and opens a new file with the specified name.

Returns

a boolean signifying success or failure.

Member Data Documentation

DtFilePrinter* DtOutputLogger::myFilePrinter

private

The file printer to log to.

DtOutputStreamBuffer* DtOutputLogger::myBuffer

private

The buffer used by the output stream.

DtOutputStream* DtOutputLogger::myLogger

private

The output stream that does all the work.

int& DtOutputLogger::myGlobalThreshold

private

The threshold to measure against. If this is less than the threshold, then do not log anything.

int DtOutputLogger::myThreshold

private

The current logging threshold for the logger. If the logger's threshold is > the global threshold, it will not log anything.

std::string DtOutputLogger::myFilename

private

the original filename to log to
