Class RecursiveToStringStyle

java.lang.Object

org.apache.commons.lang3.builder.ToStringStyle

org.apache.commons.lang3.builder.RecursiveToStringStyle

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

MultilineRecursiveToStringStyle

public class RecursiveToStringStyle
extends ToStringStyle

Works with ToStringBuilder to create a "deep" toString.

To use this class write code as follows:

 public class Job {
   String title;
   ...
 }

 public class Person {
   String name;
   int age;
   boolean smoker;
   Job job;

   ...

   public String toString() {
     return new ReflectionToStringBuilder(this, new RecursiveToStringStyle()).toString();
   }
 }
 

This will produce a toString of the format: Person@7f54[name=Stephen,age=29,smoker=false,job=Job@43cd2[title=Manager]]

Since:

3.2
