Determines the maximum number of messages per second the Consumer wants to receive. A server that understands this value will use it as an input while it determines how fast to send messages to the Consumer. Default is 0 which means Consumer does not have a preference for the message rate. Note that this property should be set before the Consumer subscribes and any changes after Consumer subscription will not have any effect until Consumer unsubscribes and resubscribes.

The number of resubscribe attempts that the Consumer makes in the event that the destination is unavailable or the connection to the destination fails. A value of -1 enables infinite attempts. A value of zero disables resubscribe attempts.

Resubscribe attempts are made at a constant rate according to the resubscribe interval value. When a resubscribe attempt is made if the underlying channel for the Consumer is not connected or attempting to connect the channel will start a connect attempt. Subsequent Consumer resubscribe attempts that occur while the underlying channel connect attempt is outstanding are effectively ignored until the outstanding channel connect attempt succeeds or fails.

The number of milliseconds between resubscribe attempts. If a Consumer doesn't receive an acknowledgement for a subscription request, it will wait the specified number of milliseconds before attempting to resubscribe. Setting the value to zero disables resubscriptions.

Resubscribe attempts are made at a constant rate according to this value. When a resubscribe attempt is made if the underlying channel for the Consumer is not connected or attempting to connect the channel will start a connect attempt.

Contains the timestamp of the most recent message this Consumer has received. This value is passed to the destination in a receive() call to request that it deliver messages for the Consumer from the timestamp forward. All messages with a timestamp value greater than the timestamp value will be returned during a poll operation. Setting this value to -1 will retrieve all cached messages from the destination.

Disconnects the Consumer from its remote destination. This method should be invoked on a Consumer that is no longer needed by an application after unsubscribing. This method does not wait for outstanding network operations to complete and does not send an unsubscribe message to the server. After invoking disconnect(), the Consumer will report that it is in an disconnected, unsubscribed state because it will not receive any more messages until it has reconnected and resubscribed. Disconnecting stops automatic resubscription attempts if they are running.

Dispatched when a message is received by the Consumer.

The MESSAGE event type; dispatched upon receipt of a message.

The value of this constant is "message".

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`message`	The message associated with this event.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.
