MetricsRegistryRegistrationHandle [constructor] | Constructors |
~MetricsRegistryRegistrationHandle [destructor] | Unregister the metric collection callback associated with this handle (if isRegistered is true), and destroy this object. |
operator= | Unregister the metric collection callback associated with this handle (if isRegistered is true). Take an ownership on the metric collection callback registration associated with the specified original handle. Afterwards, original will no longer manage the registration, and original.isRegistered() will be false. |
isRegistered | Return true if this handle has an associated registered metrics collection callback. |
swap | Exchange the associated metric collection callback registration with the one controlled by the specified other handle. |
unregister | Unregister the metric from the associated registry. Return 0 on success, and a non-zero value if this handle is not currently associated with a registered metrics collection callback. |
