Copy name / values from Map to object properties

I have an Object and a Map. I want to copy all the name / values in the Map to be property values in the Object.

So, considering:

def tony
def map =  [plenty: "66", none: "0", ...]

I want tony to have properties, plenty and none and for them to have corresponding values in the map?

Any idea how to do this in a groovy way?

If tony does not need to be from a specific class object, you can use Expando:

m = [a:1, b:2, c:"foobar"]
e = new Expando(m)
assert e.c == "foobar"

You can use something like:

class Foo { }

​def tony = new Foo()

def map =  [plenty: "66", none: "0"]

map.each{ k, v -> tony.metaClass.setProperty k, v }

tony.properties.each { println "$it.key -> $it.value" }

Output:

none -> 0
class -> class Foo
plenty -> 66
