## [Groovy] Class SimpleDataBinder

- org.grails.databinding.SimpleDataBinder

- All Implemented Interfaces and Traits:
    DataBinder

      @groovy.transform.CompileStatic
      class SimpleDataBinder
      extends java.lang.Object

  A data binder that will bind nested Maps to an object.

       class Person {
           String firstName
           Address homeAddress
       }

       class Address {
           String city
           String state
       }

       def person = new Person()
       def binder = new SimpleDataBinder()
       binder.bind person, [firstName: 'Steven', homeAddress: [city: 'St. Louis', state: 'Missouri']]
       assert person.firstName == 'Steven'
       assert person.homeAddress.city == 'St. Louis'
       assert person.homeAddress.state == 'Missouri'
