toStringHelper

public static MoreObjects.ToStringHelper toStringHelper(Object self)

Creates an instance of MoreObjects.ToStringHelper.

This is helpful for implementing Object.toString(). Specification by example:

   
   // Returns "ClassName{}"
   MoreObjects.toStringHelper(this)
       .toString();
 <p>
   // Returns "ClassName{x=1}"
   MoreObjects.toStringHelper(this)
       .add("x", 1)
       .toString();
 <p>
   // Returns "MyObject{x=1}"
   MoreObjects.toStringHelper("MyObject")
       .add("x", 1)
       .toString();
 <p>
   // Returns "ClassName{x=1, y=foo}"
   MoreObjects.toStringHelper(this)
       .add("x", 1)
       .add("y", "foo")
       .toString();
 <p>
   // Returns "ClassName{x=1}"
   MoreObjects.toStringHelper(this)
       .omitNullValues()
       .add("x", 1)
       .add("y", null)
       .toString();
   }

Note that in GWT, class names are often obfuscated.

Parameters:

self - the object to generate the string for (typically this), used only for its class name
