The given command is wrapped as the payload of the CommandMessage that is eventually posted on the
Command Bus, unless Command already implements Message. In that case, a
CommandMessage is constructed from that message's payload and MetaData.R - The type of result expected from command executioncommand - The command to dispatchcallback - The callback to notify when the command has been processed<R> R sendAndWait(Object command)
command and wait for it to execute. The result of the execution is returned when

When the thread is interrupted, this method returns null. If command execution resulted in an
exception, it is wrapped in a CommandExecutionException.
