def _x_start_ok(self, client_properties, mechanism, response, locale):
"""
select security mechanism and locale
This method selects a SASL security mechanism. ASL uses SASL
(RFC2222) to negotiate authentication and encryption.
PARAMETERS:
client_properties: table
client properties
mechanism: shortstr
selected security mechanism
A single security mechanisms selected by the client,
which must be one of those specified by the server.
RULE:
The client SHOULD authenticate using the highest-
level security profile it can handle from the list
provided by the server.
RULE:
The mechanism field MUST contain one of the
security mechanisms proposed by the server in the
Start method. If it doesn't, the server MUST close
the socket.
response: longstr
security response data
A block of opaque data passed to the security
mechanism. The contents of this data are defined by
the SASL security mechanism. For the PLAIN security
mechanism this is defined as a field table holding two
fields, LOGIN and PASSWORD.
locale: shortstr
selected message locale
A single message local selected by the client, which
must be one of those specified by the server.

def _x_open(self, virtual_host, capabilities="", insist=False):
"""
open connection to virtual host
This method opens a connection to a virtual host, which is a
collection of resources, and acts to separate multiple
application domains within a server.
RULE:
The client MUST open the context before doing any work on
the connection.
PARAMETERS:
virtual_host: shortstr
virtual host name
The name of the virtual host to work with.
RULE:
If the server supports multiple virtual hosts, it
MUST enforce a full separation of exchanges,
queues, and all associated entities per virtual
host. An application, connected to a specific
virtual host, MUST NOT be able to access resources
of another virtual host.
RULE:
The server SHOULD verify that the client has
permission to access the specified virtual host.
RULE:
The server MAY configure arbitrary limits per
virtual host, such as the number of each type of
entity that may be used, per connection and/or in
total.
capabilities: shortstr
required capabilities
The client may specify a number of capability names,
delimited by spaces. The server can use this string
to how to process the client's connection request.
insist: boolean
insist on connecting to server
In a configuration with multiple load-sharing servers,
the server may respond to a Connection.Open method
with a Connection.Redirect. The insist option tells
the server that the client is insisting on a
connection to the specified server.
RULE:
When the client uses the insist option, the server
SHOULD accept the client connection unless it is
technically unable to do so.

"""
request a connection close
This method indicates that the sender wants to close the
connection. This may be due to internal conditions (e.g. a
forced shut-down) or due to an error handling a specific
method, i.e. an exception. When a close is due to an
exception, the sender provides the class and method id of the
method which caused the exception.
RULE:
After sending this method any received method except the
Close-OK method MUST be discarded.
RULE:
The peer sending this method MAY use a counter or timeout
to detect failure of the other peer to respond correctly
with the Close-OK method.
RULE:
When a server receives the Close method from a client it
MUST delete all server-side resources associated with the
client's context. A client CANNOT reconnect to a context
after sending or receiving a Close method.
PARAMETERS:
reply_code: short
The reply code. The AMQ reply codes are defined in AMQ
RFC 011.
reply_text: shortstr
The localised reply text. This text can be logged as an
aid to resolving issues.
class_id: short
failing method class
When the close is provoked by a method exception, this
is the class of the method.
method_id: short
failing method ID
When the close is provoked by a method exception, this
is the ID of the method.
