Constructor.

Parameters

  io_service | IO service to be used by the listener.
  server_address | Address on which the TCP service should run.
  server_port | Port number on which the TCP service should run.
  tls_context | TLS context.
  idle_timeout | Timeout after which an idle TCP connection is
  filter_callback | Callback invoked during connection acceptance that can allow or deny connections based on the remote endpoint.
  family | Protocol family, AF_INET or AF_INET6.
  max_concurrent_queries | Maximum number of in-progress queries allowed. Defaults to zero (unlimited).
