Member Enumeration Documentation

Options

enum FileLogger::Options

strong

Enumerator
KEEP_OPENED	Opens the associated file when the logger is constructed and closes it in destructor. This is the default behavior of the logger, nevertheless this option can be explicitly specified to increase readability of the code.
OPEN_WHEN_WRITING	Open the file only for writing and close it immediately afterwards. If the file cannot be opened, the message is not written into the log without throwing any exception. This option implies appending to existing content.
APPEND	If the file already exists, the new messages are appended to existing content instead of erasing the file.
ADD_TIMESTAMP	Adds a time of writing before each message.
