Constructor Summary

AccessConstructor and Description
public
TcpDnsQueryEncoder()

Creates a new encoder with the default record encoder.

public
TcpDnsQueryEncoder(DnsRecordEncoder recordEncoder)

Creates a new encoder with the specified recordEncoder.

Method Summary

Modifier and TypeMethod and Description
protected Buffer
allocateBuffer(ChannelHandlerContext
the ChannelHandlerContext which this MessageToByteEncoder belongs to
ctx, DnsQuery
the message to be encoded
msg)

Implements abstract io.netty5.handler.codec.MessageToByteEncoder.allocateBuffer.

Allocate a Buffer which will be used as argument of encode(ChannelHandlerContext, I, Buffer).
protected void
encode(ChannelHandlerContext
the ChannelHandlerContext which this MessageToByteEncoder belongs to
ctx, DnsQuery
the message to encode
msg, Buffer
the Buffer into which the encoded message will be written
out)

Implements abstract io.netty5.handler.codec.MessageToByteEncoder.encode.

Encode a message into a Buffer.
public boolean
isSharable()

Overrides default io.netty5.channel.ChannelHandler.isSharable.

Returns true if this handler is sharable and thus can be added to more than one ChannelPipeline.

protected Buffer allocateBuffer(ChannelHandlerContext ctx, DnsQuery msg)

Implements abstract io.netty5.handler.codec.MessageToByteEncoder.allocateBuffer.

Doc from io.netty5.handler.codec.MessageToByteEncoder.allocateBuffer.

Allocate a Buffer which will be used as argument of encode(ChannelHandlerContext, I, Buffer).

Parameters
ctx:ChannelHandlerContext

the ChannelHandlerContext which this MessageToByteEncoder belongs to

msg:DnsQuery

the message to be encoded

protected void encode(ChannelHandlerContext ctx, DnsQuery msg, Buffer out) throws Exception

Implements abstract io.netty5.handler.codec.MessageToByteEncoder.encode.

Doc from io.netty5.handler.codec.MessageToByteEncoder.encode.

Encode a message into a Buffer. This method will be called for each written message that can be handled by this encoder.

Parameters
ctx:ChannelHandlerContext

the ChannelHandlerContext which this MessageToByteEncoder belongs to

msg:DnsQuery

the message to encode

out:Buffer

the Buffer into which the encoded message will be written

public boolean isSharable()

Overrides default io.netty5.channel.ChannelHandler.isSharable.

Doc from io.netty5.channel.ChannelHandler.isSharable.

Returns true if this handler is sharable and thus can be added to more than one ChannelPipeline. By default, this method returns false. If this method returns false, you have to create a new handler instance every time you add it to a pipeline because it has unshared state such as member variables.
