Class TsiFrameHandler

java.lang.Object
io.netty.channel.ChannelHandlerAdapter
io.netty.channel.ChannelInboundHandlerAdapter
io.netty.handler.codec.ByteToMessageDecoder
io.grpc.alts.internal.TsiFrameHandler
All Implemented Interfaces:
io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler, io.netty.channel.ChannelOutboundHandler
public final class TsiFrameHandler extends io.netty.handler.codec.ByteToMessageDecoder implements io.netty.channel.ChannelOutboundHandler
Encrypts and decrypts TSI Frames. Writes are buffered here until flush(io.netty.channel.ChannelHandlerContext) is called. Writes must not be made before the TSI handshake is complete.
