Detailed Description

Logger is the class you will use to specify the log category when logging messages with FB_LOG().

Logger is really just a small wrapper class that contains a pointer to the appropriate LogCategory object. It primarily exists as syntactic sugar to allow for easily looking up LogCategory objects.

folly::Logger::Logger ( folly::StringPiece  name )

A LogCategory object for this category will be created if one does not already exist.

Definition at line 28 of file Logger.cpp.

References folly::LoggerDB::get(), and folly::LoggerDB::getCategory().

: Logger{LoggerDB::get().getCategory(name)} {}

folly::Logger::Logger ( LogCategory *  cat )

explicit

Construct a Logger pointing to an existing LogCategory object.

: category_(cat) {}

folly::Logger::Logger	(	LoggerDB *	db,
		folly::StringPiece	name
	)

This is primarily intended for use in unit tests.
