[ccxjc-users] Superclass CopyConstructor

[Thomas B. E. M. <br...@me...>]

Hi Christian,

 

What would you think about implementing a superclass-copy-constructor
generator too?

 

 

Example:

 

The XML Schemas

 

<xsd:complexType name="Dad"/>

 

<xsd:complexType name="Son">

            <xsd:complexContent>

                        <xsd:extension base="Dad"/>

            </xsd:complexContent>

</xsd:complexType>

 

 

Could result in:

 

 

class Dad{

 

            /** default constructor */

            public Dad() {};

            

            /** standard copy-constuctor */

            public Dad(Dad d)

            {

                        // copy everything...

            }           

}

 

class Son extends Dad{

    

            /** default constructor */

            public Son() {}

 

            /** standard copy-constuctor */

    public Son(Son s) {

        // copy everything...

    }

 

            /** superclass copy-constuctor */

    Son(Dad d) {

        // copy everything from superclass...

    }

}

 

Would be very helpful when working with multilayer class hierarchies.
Perhaps it would be easy to implement into cc-xjc ???

 

Best,

Thomas

Hi,

in that superclass-copy-constructor, the properties of the class 'Son'
should not be touched at all and left to theire defaults ? So that the
constructor would actually look like:

Son(Dad d)
{
  super(d);
}

What when there is more than one superclass ?

   Root
    ^
    |
  Parent
    ^
    |
  Child

Should there be a super-superclass-constructor as well ?

Child(Child o)
{
  super(o);
  // copy properties of child.
}

Child(Parent o)
{
  super(o);
}

Child(Root o)
{
  super(o);
}

There is a 1.1-SNAPSHOT available which implements it that way. You can
download it from

<http://ccxjc.sourceforge.net/maven2/snapshots/net/sourceforge/ccxjc/cc-xjc-dist/1.1-SNAPSHOT/>

It has an added '-cc-hierarchical' option, which needs to be used to
enable those super-constructors. I haven't tested it that much but it
should work. I am not quite sure about the name of that option.
Suggestions are welcome...
