Logger

The Logger class is used to log data to the SD card in the VEX brain.

Creating a Logger

There are three different ways to create a new logger:

  1. Create a logger with no parameters (will write to log.txt):

//Create a new logger that writes to log.txt
LouLib::Utility::Logger logger;

  1. Create a logger with a file name:

//Create a new logger that writes to file.txt
std::string fileName = "file";
LouLib::Utility::Logger logger(fileName);

  1. Create a logger with a file name and file extension:

//Create a new logger that writes to file.csv
std::string fileName = "file";
std::string fileExtension = "csv";
LouLib::Utility::Logger logger(fileName, fileExtension);

Note on file names

If there already exists a file with the same name as what the logger is set to write to, the logger will write to a new file with a number added to the file name.

For example, if log.txt already exists, a new logger would write to log(1).txt, and creating another logger after that would result in a logger that writes to log(2).txt.
