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.
