Method Details

allocator

public NettyTransportSettings.Builder allocator(io.netty.buffer.ByteBufAllocator allocator)

Sets the allocator.

Parameters:

allocator - the allocator to use for ByteBuf instances

Returns:

this

• NettyTransportSettings.getAllocator()

socketChannelClass

public NettyTransportSettings.Builder socketChannelClass(Class<? extends io.netty.channel.socket.SocketChannel> socketChannelClass)

Sets the socket channel class

Parameters:

socketChannelClass - the socket channel class

Returns:

this

See Also:

• NettyTransportSettings.getSocketChannelClass()

eventLoopGroup

public NettyTransportSettings.Builder eventLoopGroup(io.netty.channel.EventLoopGroup eventLoopGroup)

Sets the event loop group.

The application is responsible for shutting down the provided eventLoopGroup. It must not be shut down before or concurrently with closing the MongoClient.

Parameters:

eventLoopGroup - the event loop group that all channels created by this factory will be a part of

Returns:

this

• NettyTransportSettings.getEventLoopGroup()

sslContext

public NettyTransportSettings.Builder sslContext(io.netty.handler.ssl.SslContext sslContext)

Sets a client-side io.netty.handler.ssl.SslContext, which overrides the standard SslSettings.getContext(). By default, it is null and SslSettings.getContext() is at play.

This option may be used as a convenient way to utilize OpenSSL as an alternative to the TLS/SSL protocol implementation in a JDK. To achieve this, specify SslProvider.OPENSSL TLS/SSL protocol provider via SslContextBuilder.sslProvider(SslProvider). Note that doing so adds a runtime dependency on netty-tcnative, which you must satisfy.

Notes:

• Netty SslContext may not examine some security/system properties that are used to customize JSSE. Therefore, instead of using them you may have to apply the equivalent configuration programmatically, if both the SslContextBuilder and the TLS/SSL protocol provider of choice support it.
• Only SslProvider.JDK and SslProvider.OPENSSL TLS/SSL protocol providers are supported.

Parameters:

sslContext - The Netty SslContext, which must be created via SslContextBuilder.forClient().

Returns:

this.

• NettyTransportSettings.getSslContext()

build

public NettyTransportSettings build()

Build an instance of NettyTransportSettings.

Returns:

an instance of NettyTransportSettings
