Method Details

decode

protected void decode(ChannelHandlerContext context,
 ByteBuf in,
 List<Object> out)
               throws Exception

Description copied from class: ByteToMessageDecoder

Decode the from one ByteBuf to an other. This method will be called till either the input ByteBuf has nothing to read when return from this method or till nothing was read from the input ByteBuf.

Specified by:

decode in class ByteToMessageDecoder

Parameters:

context - the ChannelHandlerContext which this ByteToMessageDecoder belongs to

in - the ByteBuf from which to read data

out - the List to which decoded messages should be added

Throws:

Exception - is thrown if an error occurs

newSslHandlerName

protected String newSslHandlerName()

Optionally specify the SSL handler name, this method may return null.

Returns:

the name of the SSL handler.

newSslHandler

protected SslHandler newSslHandler(ChannelHandlerContext context,
 SslContext sslContext)

Override to configure the SslHandler eg. SSLParameters.setEndpointIdentificationAlgorithm(String). The hostname and port is not known by this method so servers may want to override this method and use the SslContext.newHandler(ByteBufAllocator, String, int) variant.

Parameters:

context - the ChannelHandlerContext to use.

sslContext - the SSLContext to use.

Returns:

the SslHandler which will replace the OptionalSslHandler in the pipeline if the traffic is SSL.

newNonSslHandlerName

protected String newNonSslHandlerName()

Optionally specify the non-SSL handler name, this method may return null.

Returns:

the name of the non-SSL handler.

newNonSslHandler

protected ChannelHandler newNonSslHandler(ChannelHandlerContext context)

Override to configure the ChannelHandler.

Parameters:

context - the ChannelHandlerContext to use.

Returns:

the ChannelHandler which will replace the OptionalSslHandler in the pipeline or null to simply remove the OptionalSslHandler if the traffic is non-SSL.
