queueMessages property
Whether the default behavior whereby the library queues messages on a connection in the disconnected or connecting states is used.
The default behavior enables applications to submit messages immediately
upon instantiating the library without having to wait for the connection
to be established. Applications may use this option to disable queueing if
they wish to have application-level control over the queueing. The default
is true.
Implementation
bool queueMessages = true;
