Reading the current queue content

Hi

I am using the QUEUE recipe of Curator.

However, for some reason, I would need to know, what are the current
members of the queue at a given time.

I did not find in the API the way to do that.

Thanks!

Benjamin

getChildren returns the list of ZNodes. You must then call getData() for each node. But, the data format is private. Why do you need it? It seems strange to have Curator managing the queue and then for you to manage it as well.

Thanks Jordan

However, it returns me a list of String.
How can I pass from this String to the Object I added to the queue?

Call getChildren() on the parent node.
