Class ToStringBuilder

java.lang.Object
com.kosdev.kos.commons.util.misc.ToStringBuilder
public class ToStringBuilder extends Object
Minimal string builder used to implement toString() when the @ToString annotation isn't used. The output matches the Lombok's output.

Example

 
  public class Person {
      String name;
      int age;
      boolean rightHanded;

      // . . .

      public String toString() {
          return new ToStringBuildr(this)
              .append("name", name)
              .append("age", age)
              .append("rightHanded", rightHanded)
              .toString();
      }
  }

This will produce a toString() of the format: 

  Person[name=Stephen, age=29, rightHanded=false]
