Value members
Abstract methods
Handle the prior knowledge preface
Handle the prior knowledge preface
The preface is the magic string "PRI * HTTP/2.0\r\n\r\nSM\r\n\r\n" which is intended to cause HTTP/1.x connections to fail gracefully. For clients, this involves sending the magic string and for servers this consists of receiving the magic string. The return value of this function is any unconsumed inbound data.

Shuts down the stage, deallocating resources, etc.
Shuts down the stage, deallocating resources, etc.
It will be called when the stage receives a Disconnected
command unless inboundCommand
is overridden. This method should not send or Disconnected
commands.
It is possible that this will not be called due to failure of other stages to propagate shutdown commands. Conversely, it is also possible for this to be called more than once due to the reception of multiple shutdown commands. It is therefore recommended that the method be idempotent.

Start the stage, allocating resources etc.
Start the stage, allocating resources etc.
This method should not effect other stages by sending commands etc unless it creates them. It
is not impossible that the stage will receive other commands besides Connected
before this
method is called. It is not impossible for this method to be called multiple times by
misbehaving stages. It is therefore recommended that the method be idempotent.
