It seems some of the changes made here will conflict with the chengs made in the tree-id branch. Ghislain can you try to merge the trunk into this branch and resolve the conflicts?

Also, I don't like the fact that a zstring (i.e., theValue) is now just wasted space in each StructuralAnyUriItem. Either make theValue mutable so that it can be reused by StructuralAnyUriItem, or don't make StructuralAnyUriItem a subclass of AnyUriItem anymore (it dosn't inherit much from AnyUriItem anymore).

Now that the StructuralAnyUriItem does not inherit from AnyUriItem anymore, the method getAnyUriTypeCode() should be added (as virual) to the AtomicItem class, with a default implementation throwing an error.

Ghislain, you changed the StructuralAnyUriItem constructor to take a const zstring&, instead of zstring&. I prefer that you revert this change (because the old way is more consistent with the rest of the item factory methods), but if want to keep the "const" it's ok, but then the use of the temp zstring variable in methods inAncestor, isFollowing, etc is no longer needed (in both their StructuralAnyUriItem and AnyUriItem versions). The static_cast of the aOther param in those methods is also not needed any more.

Hi Markos,

Thanks for your feedback, this is fixed for consistency (though in general, I prefer to have all references const in function parameters).

However, I could not find why the static_cast is not needed - the methods and variables are not part of the zorba::store::Item API?

Markos Zaharioudakis (markos-za) wrote :

Hi Ghislain,

The point of the non-const param is to call take() inside the constructor, thus saving a (synchronized) ref counting. I have now added this take() call in the StructuralAnyURIItem constructor.

You are right about the static casts. I thought that getAnyUriTypeCode() was a zorba::Item method. I have added a ZORBA_ASSERT() to make sure that the "aOther" param is indeed an atomic item.
