copy constructor for inherited types?

[Stefan Lischke <s....@zertificon.com>]

hi there,

I have to xsd types. Type A and B. B extends A and adds another element.

In source i have an instance of A and want to create a new instance of B
from A.

Any ideas? something like B.Factory.newInstance(A) for example? or do i
have to copy all fields by myself?

I tried with B.set(A) but B gets orphaned after this and i cannot set
the value of the extended Element of B

thanx in advance

Stefan

Like in java, using only XMLObject's typed methods you have to set each
field.

But if you use XMLCursor API (which is not typed) you can copy or even
better (performance wise) move content from a to b.
