The client identifier
Return a negative integer, zero, or a positive integer if this object is less than, equal to, or greater than the specified object:
this < that => <0
this == that => 0
this > that => >0
This method may also be accessed via the <
<=
<=>
>=
and >
shortcut operators. If not overridden the default
implementation compares the toStr
representations. Also see docLang.
Examples:
3.compare(8) => -1
8.compare(3) => 1
8.compare(8) => 0
3 <=> 8 => -1 // shortcut for 3.compare(8)
Compare this object to the specified for equality. This
method may be accessed via the == and != shortcut operators.
If not overridden the default implementation compares for
reference equality using the === operator. If this method
is overridden, then hash() must also be overridden such that
any two objects which return true for equals() must return
the same value for hash(). This method must accept null
and
return false.
Return a unique hashcode for this object. If a class overrides hash() then it must ensure if equals() returns true for any two objects then they have same hash code.
Maximum number of messages requiring acknowledgement that can be in-flight.
How many times to retry messages that require acknowledgement
How long to wait for CONNACK before timing out the connection
The persistence layer to use for this client
Actor pool for client actors
How long to wait between retries for messages that require acknowledgement
The MQTT server uri to connect to.
To connect via the TCP transport use either the mqtt
(plain
socket) or mqtts
(TLS socket) scheme.
To connect via a websocket use either the ws
(plain socket)
or wss
(TLS socket) scheme.
The socket configuration to use.
How long until unacknowledged messages timeout
Get an immutable representation of this instance or throw NotImmutableErr if this object cannot be represented as an immutable:
Return a string representation of this object.
Trap a dynamic call for handling. Dynamic calls are invoked with the -> shortcut operator:
a->x a.trap("x", null)
a->x() a.trap("x", null)
a->x = b a.trap("x", [b])
a->x(b) a.trap("x", [b])
a->x(b, c) a.trap("x", [b, c])
The default implementation provided by Obj attempts to use reflection. If name maps to a method, it is invoked with the specified arguments. If name maps to a field and args.size is zero, get the field. If name maps to a field and args.size is one, set the field and return args[0]. Otherwise throw UnknownSlotErr.
The MQTT protocol version to use
This method called whenever an it-block is applied to an
object. The default implementation calls the function with this
,
and then returns this
.
Static
echoWrite x.toStr
to standard output followed by newline. If x
is null then print "null". If no argument is provided then
print an empty line.
Optional

make
The configuration to use when creating an MqttClient.
