      • build

        DoubleCounter build()
        Builds and returns a Counter instrument with the configuration.
        Returns:
        The Counter instrument.

      • buildWithCallback

        ObservableDoubleCounter buildWithCallback​(java.util.function.Consumer<ObservableDoubleMeasurement> callback)
        Builds an Asynchronous Counter instrument with the given callback.

        The callback will be called when the instrument is being observed.

        Callbacks are expected to abide by the following restrictions:

        • Run in a finite amount of time.
        • Safe to call repeatedly, across multiple threads.
        Parameters:
        callback - A callback which observes measurements when invoked.

      • buildObserver

        default ObservableDoubleMeasurement buildObserver()
        Build an observer for this instrument to observe values from a BatchCallback.

        This observer MUST be registered when creating a batchCallback, which records to it. Values observed outside registered callbacks are ignored.

        Returns:
        an observable measurement that batch callbacks use to observe values.
