Annotation Interface ToString

@Beta @Target(TYPE) @GwtCompatible public @interface ToString
Creates a default toString implementation.

All non-static fields of this class and all of its superclasses are used. Reflection is used to access all fields if this class has a superclass. This may not work in restrictive environments. For such cases use ToStringBuilder to write a non-reflective implementation.

The default format is: 
  ClassName [
    field1 = "Foo"
    field2 = 2
    field3 = null
  ]
The class name is hardcoded. Subclasses which inherit this class without overriding toString will show the same name.

For brevity there are options to hide field names, skip fields with null values and print everything on one line.
