Why isn't this closure working?

Question

I have the following closure:

def deepSave = {
    it.attributes.each{it.save(validate: false)}
    it.elements.each{deepSave(it)}
    it.save(validate: false)
}         


        

Answer 1

I am not sure about the validity of the scenario where you are doing the recursion but when you use closure for recursion the variable has to be pre-defined before it is tailored so that it can know about itself during recursion. For example:

def deepSave
deepSave = {
    it.attributes.each{it.save(validate: false)}
    it.elements.each{deepSave(it)}
    it.save(validate: false)
}

I could not figure out an exit strategy from the recursion, but I can add some more to it if you can elaborate on the context and add a breaking sample to run.
