std.logger.core.Logger.log - multiple declarations

Function Logger.log

This method logs data with the LogLevel of the used Logger.

void log(int line = __LINE__, string file = __FILE__, string funcName = __FUNCTION__, string prettyFuncName = __PRETTY_FUNCTION__, string moduleName = __MODULE__, A...) (
  const LogLevel ll,
  lazy bool condition,
  lazy A args
)
if (args.length != 1);

void log(T, string moduleName = __MODULE__) (
  const LogLevel ll,
  lazy bool condition,
  lazy T args,
  int line = __LINE__,
  string file = __FILE__,
  string funcName = __FUNCTION__,
  string prettyFuncName = __PRETTY_FUNCTION__
);

This method takes a bool as first argument. In order for the data to be processed the bool must be true and the LogLevel of the Logger must be greater or equal to the global LogLevel.

Parameters

NameDescription
args The data that should be logged.
condition The condition must be true for the data to be logged.
args The data that is to be logged.

Returns

The logger used by the logging function as reference.

Example

auto l = new StdioLogger();
l.log(1337);

Function Logger.log

This function logs data to the used Logger with a specific LogLevel.

void log(int line = __LINE__, string file = __FILE__, string funcName = __FUNCTION__, string prettyFuncName = __PRETTY_FUNCTION__, string moduleName = __MODULE__, A...) (
  const LogLevel ll,
  lazy A args
)
if (args.length > 1 && !is(Unqual!(A[0]) : bool) || args.length == 0);

void log(T) (
  const LogLevel ll,
  lazy T args,
  int line = __LINE__,
  string file = __FILE__,
  string funcName = __FUNCTION__,
  string prettyFuncName = __PRETTY_FUNCTION__,
  string moduleName = __MODULE__
);

In order for the resulting log message to be logged the LogLevel must be greater or equal than the LogLevel of the used Logger and must be greater or equal than the global LogLevel.

Parameters

NameDescription
ll The specific LogLevel used for logging the log message.
args The data that should be logged.

Example

auto s = new FileLogger(stdout);
s.log(LogLevel.trace, 1337, "is number");
s.log(LogLevel.info, 1337, "is number");
s.log(LogLevel.warning, 1337, "is number");
s.log(LogLevel.error, 1337, "is number");
s.log(LogLevel.fatal, 1337, "is number");

Function Logger.log

This function logs data to the used Logger depending on a explicitly passed condition with the LogLevel of the used Logger.

void log(int line = __LINE__, string file = __FILE__, string funcName = __FUNCTION__, string prettyFuncName = __PRETTY_FUNCTION__, string moduleName = __MODULE__, A...) (
  lazy bool condition,
  lazy A args
)
if (args.length != 1);

void log(T) (
  lazy bool condition,
  lazy T args,
  int line = __LINE__,
  string file = __FILE__,
  string funcName = __FUNCTION__,
  string prettyFuncName = __PRETTY_FUNCTION__,
  string moduleName = __MODULE__
);

In order for the resulting log message to be logged the LogLevel of the used Logger must be greater or equal than the global LogLevel and the condition must be true.

Parameters

NameDescription
condition The condition must be true for the data to be logged.
args The data that should be logged.

Example

auto s = new FileLogger(stdout);
s.log(true, 1337, "is number");
s.log(true, 1337, "is number");
s.log(true, 1337, "is number");
s.log(false, 1337, "is number");
s.log(false, 1337, "is number");

Function Logger.log

This function logs data to the used Logger with the LogLevel of the used Logger.

void log(int line = __LINE__, string file = __FILE__, string funcName = __FUNCTION__, string prettyFuncName = __PRETTY_FUNCTION__, string moduleName = __MODULE__, A...) (
  lazy A args
)
if (args.length > 1 && !is(Unqual!(A[0]) : bool) && !is(immutable(A[0]) == immutable(LogLevel)) || args.length == 0);

void log(T) (
  lazy T arg,
  int line = __LINE__,
  string file = __FILE__,
  string funcName = __FUNCTION__,
  string prettyFuncName = __PRETTY_FUNCTION__,
  string moduleName = __MODULE__
);

In order for the resulting log message to be logged the LogLevel of the used Logger must be greater or equal than the global LogLevel.

Parameters

NameDescription
args The data that should be logged.

Example

auto s = new FileLogger(stdout);
s.log(1337, "is number");
s.log(info, 1337, "is number");
s.log(1337, "is number");
s.log(1337, "is number");
s.log(1337, "is number");
