class DRb::DRbSSLSocket

This is called automatically based on the DRb protocol.

+is_established+ is a boolean of whether +soc+ is currently established
+config+ is our configuration. Either a Hash or SSLConfig
+soc+ is the tcp socket we are bound to.
+uri+ is the URI we are connected to.

Create a DRb::DRbSSLSocket instance.

def initialize(uri, soc, config, is_established)
  @ssl = is_established ? soc : nil
  super(uri, soc.to_io, config)
end
