Help with how to create messages with `inject` node

General
1

Usually the inject node injects stuff in msg.payload.

You can edit the topic in another field.

Just because I want to optimise node usage:
Is there a way to make the inject node send a msg.flush message?

I'm guessing it uses the { } option.

In a function node, it is this:

msg = {
    'flush':'blah'
};

But I am not getting how to put that in the inject node.

Please.

No. The Inject node can only set payload and/or topic.

On that, it is the delay node which has caught my interest.

It says if I inject a flush all messages will be flushed.
To me that means they are forgotten.

(Nic, I saw your reply come in. I'll read it after posting this)

This flow is basically what I want done.

I press the message node. It is delayed 5 seconds.

But as I see it, if I press the flush button the node should be flushed.

I still get the message.

Why?

Ah! I need to send a reset message too.

My bad.

Post left to help anyone else who may fall for that trap.

No
Reset will reset the node. I.E. forget everything (which is what you want.)
Flush will send everything stored up immediately (like unblocking/flushing a pipe)

My bad.

I tripped on that. I read it and mis-parsed it.

What I think it was is I am using some `trigger` and some `delay` nodes. In the `trigger` node `reset` clears all messages. In the `delay` node `reset` . . . . I'm confused. I'll shut up.

All working now.

Thanks.
