Method Detail

acquireCreationPermit

public boolean acquireCreationPermit(long acquireStartTime,
                                     java.util.concurrent.TimeUnit timeUnit)

Description copied from interface: PoolLimitDeterminationStrategy

Attempts to acquire a creation permit.

Specified by:

acquireCreationPermit in interface PoolLimitDeterminationStrategy

Parameters:

acquireStartTime - The start time for the acquire process in milliseconds since epoch.

timeUnit - The timeunit for the acquire start time.

Returns:

true if the permit was acquired, false otherwise.

getAvailablePermits

public int getAvailablePermits()

Returns the minimum number of permits available across all strategies.

Specified by:

getAvailablePermits in interface PoolLimitDeterminationStrategy

Returns:

The minimum number of permits available across all strategies.

onEvent

public void onEvent(ClientMetricsEvent<?> event,
                    long duration,
                    java.util.concurrent.TimeUnit timeUnit,
                    java.lang.Throwable throwable,
                    java.lang.Object value)

Description copied from interface: MetricEventsListener

Event callback for any MetricsEvent. The parameters passed are all the contextual information possible for any event. There presence or absence will depend on the type of event.

Specified by:

onEvent in interface MetricEventsListener<ClientMetricsEvent<?>>

Parameters:

event - Event for which this callback has been invoked. This will never be null

duration - If the passed event is MetricsEvent.isTimed() then the actual duration, else MetricEventsListener.NO_DURATION

timeUnit - The time unit for the duration, if exists, else MetricEventsListener.NO_TIME_UNIT

throwable - If the passed event is MetricsEvent.isError() then the cause of the error, else MetricEventsListener.NO_ERROR

value - If the passed event requires custom object to be passed, then that object, else MetricEventsListener.NO_VALUE

onCompleted

public void onCompleted()

Description copied from interface: MetricEventsListener

Marks the end of all event callbacks. No methods on this listener will ever be called once this method is called.

Specified by:

onCompleted in interface MetricEventsListener<ClientMetricsEvent<?>>

onSubscribe

public void onSubscribe()

Description copied from interface: MetricEventsListener

A callback when this listener is subscribed to a MetricEventsPublisher.

Specified by:

onSubscribe in interface MetricEventsListener<ClientMetricsEvent<?>>
