I think we need additional clarification on what you mean by “variables”. If
you are referring to actual Groovy variables, you can enumerate them using the
binding available in the context (see below). If you mean the attributes
available on a flowfile, you can access them similarly.
Find all variables starting with prefix:
def varsStartingWithABC = this.binding.variables.findAll { k,v ->
k.startsWith(“a.b.c”) }
Find all attributes starting with prefix:
def attrsStartingWithABC = flowfile.getAttributes().findAll { k,v ->
k.startsWith(“a.b.c”) }
