Specified by:

build in interface DoubleCounterBuilder

Returns:

The Counter instrument.

setDescription

public DoubleCounterBuilder setDescription(java.lang.String description)

Description copied from interface: DoubleCounterBuilder

buildWithCallback

public ObservableDoubleCounter buildWithCallback(java.util.function.Consumer<ObservableDoubleMeasurement> callback)

Description copied from interface: DoubleCounterBuilder

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.

Specified by:

buildWithCallback in interface DoubleCounterBuilder

Parameters:

callback - A callback which observes measurements when invoked.

buildObserver

public ObservableDoubleMeasurement buildObserver()

Description copied from interface: DoubleCounterBuilder

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 DoubleCounterBuilder

Returns:

an observable measurement that batch callbacks use to observe values.

setAttributesAdvice

public ExtendedDoubleCounterBuilder setAttributesAdvice(java.util.List<AttributeKey<?>> attributes)

Description copied from interface: ExtendedDoubleCounterBuilder

Specify the attribute advice, which suggests the recommended set of attribute keys to be used for this counter.

Specified by:

setAttributesAdvice in interface ExtendedDoubleCounterBuilder

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
