Constructors
LabeledMetric 
LabeledMetric(
Type type,
const std::string & name
);
Creates a LabeledMetric with the given type and name, and registers it with the default Registry.
The name must be a valid metric name and match the regular expression [a-zA-Z_:][a-zA-Z0-9_:]*.
LabeledMetric
LabeledMetric(
Type type,
const std::string & name,
Registry * pRegistry
);
Creates a LabeledMetric with the given type and name, and registers it with the given Registry (if not nullptr).
The name must be a valid metric name and match the regular expression [a-zA-Z_:][a-zA-Z0-9_:]*.
Destructor
~LabeledMetric 
virtual ~LabeledMetric() = default;
Destroys the LabeledMetric.
Member Functions
labelNames
const std::vector < std::string > & labelNames() const;
Returns the metric's label names.
setLabelNames
void setLabelNames(
const std::vector < std::string > & labelNames
);
Sets the metric's label names.
validateLabelName 
static const std::string & validateLabelName(
const std::string & name
);
Validates the given name against the regular expression defining a valid label name ([a-zA-Z_:][a-zA-Z0-9_:]*).
Variables
EMPTY_LABEL
static const std::vector < std::string > EMPTY_LABEL;
