Question

Im trying to create a Domain Class Constructor that inherits another class properties dynamically. But I cannot get it to work properly.

Heres an example:

class Example1 {

  String name;
  String location;
}

class Example2 extends Example1 {

  String status;

  public Example2 (Example1 orig){
    // Code here to set this.name and this.location  to name and location from orig
    // dynamically, so adding a field in Example1 does not require me to add that 
    // field here.
  }
}

Answer 1

After enough troubleshooting and searching online I found a solution, here it is in case anyone is ever looking for something similar:

public Example2(Example1 orig){
   def d = new DefaultGrailsDomainClass(Example1.class)
   d.persistentProperties.each { val ->
       this[val.name] = orig[val.name]         
   }       
}

Include this:

import org.codehaus.groovy.grails.commons.DefaultGrailsDomainClass
