Class ReactorResources

java.lang.Object

discord4j.common.ReactorResources

public class ReactorResources
extends Object

Provides Reactor Netty resources like an HttpClient and Scheduler instances that can be customized and reused across the application.

Allow a user to externally manage the connection pool through a custom ConnectionProvider, and custom event loop threads using a LoopResources.

Constructor Detail

ReactorResources

public ReactorResources()

Create with a default HttpClient and Schedulers for timed and blocking tasks.

ReactorResources

public ReactorResources(HttpClient httpClient,
                        Scheduler timerTaskScheduler,
                        Scheduler blockingTaskScheduler)

Create with a pre-configured HttpClient and Schedulers for timed and blocking tasks.

Parameters:

httpClient - the underlying HttpClient to use

timerTaskScheduler - the time-capable Scheduler to use

blockingTaskScheduler - the Scheduler to use for potentially blocking tasks

ReactorResources

protected ReactorResources(ReactorResources.Builder builder)

Method Detail

create

public static ReactorResources create()

builder

public static ReactorResources.Builder builder()

getHttpClient

public HttpClient getHttpClient()

Get the HttpClient configured by this provider.

Returns:

a Reactor Netty HTTP client ready to perform requests

getTimerTaskScheduler

public Scheduler getTimerTaskScheduler()

Get the Scheduler configured by this provider to be used in timed tasks.

Returns:

a time-capable Scheduler

getBlockingTaskScheduler

public Scheduler getBlockingTaskScheduler()

Get the Scheduler configured by this provider to be used in blocking tasks.

Returns:

a blocking-capable Scheduler

newHttpClient

public static HttpClient newHttpClient(ConnectionProvider provider,
                                       LoopResources resources)

Create a Reactor Netty HttpClient using the given connection pool and event loop threads.

Use this in case you want dedicated resources for a particular client or clients instead of the global default. Requires externally disposing of the given parameters on application shutdown, through ConnectionProvider.dispose() and LoopResources.dispose().

Parameters:

provider - the connection pool provider to use

resources - the set of event loop threads to use

Returns:

an HttpClient configured with custom resources
