Method Detail

get

public static UdpResources get()

Return the global UDP resources for pooling

Returns:

the global UDP resources for pooling

set

public static UdpResources set(LoopResources loops)

Update pooling resources and return the global UDP resources

Parameters:

loops - the eventual new LoopResources

Returns:

the global UDP resources

reset

public static UdpResources reset()

Reset UDP resources to default and return its instance

Returns:

the global UDP resources

shutdown

public static void shutdown()

Shutdown the global UdpResources without resetting them, effectively cleaning up associated resources without creating new ones.

shutdownLater

public static reactor.core.publisher.Mono<java.lang.Void> shutdownLater()

Prepare to shutdown the global UdpResources without resetting them, effectively cleaning up associated resources without creating new ones. This only occurs when the returned Mono is subscribed to.

Returns:

a Mono triggering the shutdown() when subscribed to.

dispose

public void dispose()

Specified by:

dispose in interface reactor.core.Disposable

Specified by:

dispose in interface LoopResources

disposeLater

public reactor.core.publisher.Mono<java.lang.Void> disposeLater()

Description copied from interface: LoopResources

Returns a Mono that triggers the disposal of underlying resources when subscribed to.

Specified by:

disposeLater in interface LoopResources

Returns:

a Mono representing the completion of resources disposal.

_dispose

protected void _dispose()

Dispose underlying resources

_disposeLater

protected reactor.core.publisher.Mono<java.lang.Void> _disposeLater()

Dispose underlying resources in a listenable fashion.

Returns:

the Mono that represents the end of disposal

isDisposed

Description copied from interface: LoopResources

Callback for client EventLoopGroup creation.

Specified by:

onClient in interface LoopResources

Parameters:
