FileLogger

This Logger implementation writes log messages to the associated file. The name of the file has to be passed on construction time. If the file is already present new log messages will be append at its end.

class FileLogger : Logger {

struct Tid via import std.concurrency : Tid;;

struct SysTime via import std.datetime.systime : SysTime;;

uint formattedWrite(Writer w, Args args) via import std.format.write : formattedWrite;;

this(string fn, LogLevel lv);

this(string fn, LogLevel lv, CreateFolder createFileNameFolder);

this(File file, LogLevel lv);

File file [@property getter];

string getFilename();

}

Constructors

this this(string fn, LogLevel lv): A constructor for the FileLogger Logger.
this this(string fn, LogLevel lv, CreateFolder createFileNameFolder): A constructor for the FileLogger Logger that takes a reference to a File.
this this(File file, LogLevel lv): A constructor for the FileLogger Logger that takes a reference to a File.

Members

Functions

getFilename string getFilename(): If the FileLogger was constructed with a filename, this method returns this filename. Otherwise an empty string is returned.

Properties

file File file [@property getter]: If the FileLogger is managing the File it logs to, this method will return a reference to this File.

Variables

file_ File file_;: The File log messages are written to.
filename string filename;: The filename of the File log messages are written to.

Inherited Members

From Logger

LogEntry struct LogEntry: LogEntry is a aggregation combining all information associated with a log message. This aggregation will be passed to the method writeLogMsg.
writeLogMsg void writeLogMsg(LogEntry payload): A custom logger must implement this method in order to work in a MultiLogger and ArrayLogger.
logMsgPart void logMsgPart(const(char)[] msg): Logs a part of the log message.
finishLogMsg void finishLogMsg(): Signals that the message has been written and no more calls to logMsgPart follow.
logLevel LogLevel logLevel [@property getter]
LogLevel logLevel [@property setter]: The LogLevel determines if the log call are processed or dropped by the Logger. In order for the log call to be processed the LogLevel of the log call must be greater or equal to the LogLevel of the logger.
fatalHandler void delegate() fatalHandler [@property getter]
void delegate() @(safe) fatalHandler [@property setter]: This delegate is called in case a log message with LogLevel.fatal gets logged.
forwardMsg void forwardMsg(LogEntry payload): This method allows forwarding log entries from one logger to another.
