Description

It would be nice if Groovy allows developers to create a map from selected properties of an Object.

Below are the example:

Example

class Hero {
    String name
    Integer strength
    Integer constitution
    String weakness
}

Hero hero = new Hero(name: "Robin", strength: 70, constitution: 80, weakness: "Beautiful Women")

def mapNoWeakness = hero.asMap(['name', 'strength', 'constitution'])

println mapNoWeakness // [name: 'Robin', strength: 70, constitution: 80]

def mapOnlyName = hero.asMap(['name'])

println mapOnlyName // [name: 'Robin']
