ConnectionPoolImpl

public ConnectionPoolImpl(RxClient.ServerInfo serverInfo,
                  PoolConfig poolConfig,
                  PoolLimitDeterminationStrategy strategy,
                  java.util.concurrent.ScheduledExecutorService cleanupScheduler,
                  ClientChannelFactory<I,O> channelFactory,
                  MetricEventsSubject<ClientMetricsEvent<?>> eventsSubject)

Creates a new connection pool instance.

Parameters:

serverInfo - Server to which this pool connects.

poolConfig - The pool configuration.

strategy - Pool limit determination strategy. This can be null

cleanupScheduler - Pool idle cleanup scheduler. This can be null which means there will be

eventsSubject - Metrics event subject to use.

Method Detail

acquire

public rx.Observable<ObservableConnection<I,O>> acquire()

Specified by:

acquire in interface ConnectionPool<I,O>

release

public rx.Observable<java.lang.Void> release(PooledConnection<I,O> connection)

Specified by:

release in interface ConnectionPool<I,O>

discard

public rx.Observable<java.lang.Void> discard(PooledConnection<I,O> connection)

Description copied from interface: ConnectionPool

Discards the passed connection from the pool. This is usually called due to an external event like closing of a connection that the pool may not know.
This operation is idempotent and hence can be called multiple times with no side effects

Specified by:

discard in interface ConnectionPool<I,O>

Parameters:

connection - The connection to discard.

Returns:

Observable indicating the completion of the discard operation. Since, this operation is idempotent, the returned observable does not indicate throw an error if the eviction of this connection was not due to that particular invocation.

shutdown

public void shutdown()

Specified by:

shutdown in interface ConnectionPool<I,O>

subscribe

public rx.Subscription subscribe(MetricEventsListener<? extends ClientMetricsEvent<?>> listener)

Specified by:

subscribe in interface MetricEventsPublisher<ClientMetricsEvent<?>>
