Suggestion for Clone Builder in commons-lang to assist with Cloneable and clone()

[Vihung Marathe <vi...@friendsprovident.co.uk>]

Given that it is considered 'good practice' for entity objects to be
Cloneable and to have a 'proper' clone() method, can I suggest that
there be a CloneBuilder builder along the lines of HashCodeBuilder et
al.

I would expect to use it in my implementation of clone() methods as
follows

  public Object clone() throws CloneNotSupportedException {
      return CloneBuilder.reflectionClone(this);
  }

to use reflection to build a generic clone

or

  public Object clone() throws CloneNotSupportedException {
      return new CloneBuilder(this)
          .append("field1")         // note the 'field by name' usage
          .append("field2")         // rather than 'field by value'
          ...
          .append("fieldn")
          .toClone()
      ;
  }

to build a clone from specific named fields.
