ALPNServerSelector

final class ALPNServerSelector(engine: SSLEngine, selector: Set[String] => String, builder: String => LeafBuilder[ByteBuffer]) extends TailStage[ByteBuffer]

Dynamically inject an appropriate pipeline using ALPN negotiation.

Value Params
builder

builds the appropriate pipeline based on the negotiated protocol

engine

the SSLEngine in use for the connection

selector

selects the preferred protocol from the sequence of supported clients. May receive an empty sequence.

protected def stageShutdown(): Unit

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.
