is there a way to capture the iterator during an apply?

[ryanpodonnell1]

seems like I can only ever reference the current message in the processor chain aka this.
example:

input:

{ "somefield" : "somevalue", "componenents" : [ {"someinnerkey" :  "someinnervalue"}] }

mapping:

#!blobl
map myexamplemapping {
root.rename_inner_key = this.someinnerkey
}

root = this.components.map_each(c -> c.apply("myexamplemapping")).flatten()

want:

[ {"rename_inner_key" : "someinnervalue" } ]

I wish there was some way to capture a given iterator like this:

// x = this
map myexamplemapping(x) {

}


root = this.components.map_each(c -> c.apply("myexamplemapping",c)).flatten()

Hey @ryanpodonnell1, not sure what you're looking to do, but maybe this helps you:

map myexamplemapping {
    root.rename_inner_key = this.component.someinnerkey
    # do something with `this.components`
}

let components = this.componenents

root = $components.map_each(c -> {"component": c, "components": $components}.apply("myexamplemapping")).flatten()
