Abstract methods
Creates an asynchronous instrument based on an effect that produces a number of measurements.
Creates an asynchronous instrument based on an effect that produces a number of measurements.
The measurement effect will be evaluated when the instrument is being observed.
The measurement effect is expected to abide by the following restrictions:
-
Short-living and (ideally) non-blocking
-
Run in a finite amount of time
-
Safe to call repeatedly, across multiple threads
Value parameters
- measurements
-
effect that produces a number of measurements
Attributes
Creates an observer for this instrument to observe values from a BatchCallback.
Creates an observer for this instrument to observe values from a BatchCallback.
Attributes
- Note
-
The observer must be registered via Meter.batchCallback. Values observed outside registered callbacks are ignored.

- ObservableUpDownCounter.scala
Creates an instrument with the given callback, using unit and description (if any).
Creates an instrument with the given callback, using unit and description (if any).
The callback will be called when the instrument is being observed.
The callback is expected to abide by the following restrictions:
-
Short-living and (ideally) non-blocking
-
Run in a finite amount of time
-
Safe to call repeatedly, across multiple threads
Value parameters
- cb
-
the callback which observes measurements when invoked
