Constructor Detail

KeyValueMessageHandler

public KeyValueMessageHandler(BaseEndpoint endpoint,
                              EndpointContext endpointContext,
                              Optional<String> bucketName)

Creates a new KeyValueMessageHandler.

Parameters:

endpointContext - the parent core context.

Method Detail

channelActive

public void channelActive(com.couchbase.client.core.deps.io.netty.channel.ChannelHandlerContext ctx)

Actions to be performed when the channel becomes active.

Since the opaque is incremented in the handler below during bootstrap but now is only modified in this handler, cache the reference since the attribute lookup is more costly.

Specified by:

channelActive in interface com.couchbase.client.core.deps.io.netty.channel.ChannelInboundHandler

Overrides:

channelActive in class com.couchbase.client.core.deps.io.netty.channel.ChannelInboundHandlerAdapter

Parameters:

ctx - the channel context.

write

public void write(com.couchbase.client.core.deps.io.netty.channel.ChannelHandlerContext ctx,
                  Object msg,
                  com.couchbase.client.core.deps.io.netty.channel.ChannelPromise promise)

Specified by:

write in interface com.couchbase.client.core.deps.io.netty.channel.ChannelOutboundHandler

Overrides:

write in class com.couchbase.client.core.deps.io.netty.channel.ChannelDuplexHandler

channelRead

public void channelRead(com.couchbase.client.core.deps.io.netty.channel.ChannelHandlerContext ctx,
                        Object msg)

Specified by:

channelRead in interface com.couchbase.client.core.deps.io.netty.channel.ChannelInboundHandler

Overrides:

channelRead in class com.couchbase.client.core.deps.io.netty.channel.ChannelInboundHandlerAdapter

channelInactive

public void channelInactive(com.couchbase.client.core.deps.io.netty.channel.ChannelHandlerContext ctx)

Specified by:

channelInactive in interface com.couchbase.client.core.deps.io.netty.channel.ChannelInboundHandler

Overrides:

channelInactive in class com.couchbase.client.core.deps.io.netty.channel.ChannelInboundHandlerAdapter
