void Datacratic::MultiOutput::clearStats

(

)

[virtual]

Clears the current value of stats. Default implementation does nothing.

Reimplemented from Datacratic::LogOutput.

Definition at line 208 of file multi_output.cc.

void Datacratic::MultiOutput::close

(

)

[virtual]

Should close whatever resources are being used by the output and join any threads that it's created.

Implements Datacratic::LogOutput.

Definition at line 194 of file multi_output.cc.

void Datacratic::MultiOutput::logMessage	(	const std::string &	channel,
		const std::string &	message
	)		[virtual]

This is the method that will be called whenever we need to log a message to something.

Implements Datacratic::LogOutput.

Definition at line 142 of file multi_output.cc.

void Datacratic::MultiOutput::logTo	(	const std::string &	channel,
		const std::string &	pattern,
		const CreateLogger &	createLogger
	)

Set up the output class to log messages of the given type to files with the given pattern.

channel - the channel that will be matched by this rule. If the field is the empty string, then the rule will match any non-matching channels. pattern - The pattern to decide which file it should be logged to. It understands %(0), %(1), ... %(nnnnn) to mean field nnnnn from the message (where %(0) is the channel). createLogger - The function to be called to create a subordinate logger for the given filename.

Definition at line 180 of file multi_output.cc.

Json::Value Datacratic::MultiOutput::stats

(

)

const [virtual]

Should return a JSON object containing whatever stats have been accumulated since last time clearStats() was called.

Default returns an empty JSON object.
