Constructor Detail

TsiHandshakeHandler

public TsiHandshakeHandler(io.netty.channel.ChannelHandler next,
                           NettyTsiHandshaker handshaker,
                           TsiHandshakeHandler.HandshakeValidator handshakeValidator,
                           io.grpc.ChannelLogger negotiationLogger)

Constructs a TsiHandshakeHandler.

TsiHandshakeHandler

public TsiHandshakeHandler(io.netty.channel.ChannelHandler next,
                           NettyTsiHandshaker handshaker,
                           TsiHandshakeHandler.HandshakeValidator handshakeValidator,
                           AsyncSemaphore semaphore,
                           io.grpc.ChannelLogger negotiationLogger)

Constructs a TsHandshakeHandler. If a semaphore is provided, a permit from the semaphore is required to start the handshake and is returned when the handshake ends.
