ofDoubles in interface LongUpDownCounterBuilder

build

public LongUpDownCounter build()

Description copied from interface: LongUpDownCounterBuilder

Builds and returns an UpDownCounter instrument with the configuration.

Specified by:

build in interface LongUpDownCounterBuilder

Returns:

The UpDownCounter instrument.

buildWithCallback

public ObservableLongUpDownCounter buildWithCallback(Consumer<ObservableLongMeasurement> callback)

Description copied from interface: LongUpDownCounterBuilder

Builds an Asynchronous UpDownCounter 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.

Specified by:

buildWithCallback in interface LongUpDownCounterBuilder

Parameters:

callback - A callback which observes measurements when invoked.

buildObserver

public ObservableLongMeasurement buildObserver()

Description copied from interface: LongUpDownCounterBuilder

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.

Specified by:

buildObserver in interface LongUpDownCounterBuilder

Returns:

an observable measurement that batch callbacks use to observe values.
