element default value in generated classes
Hi,
I have a default value specified in the definition of the element. But the
generated class returns the default value only if the element exists in the
xml document.
schema:
<complexType name="SomeType">
<sequence>
<element name="name" type="string" minOccurs="1"/>
<element name="interval" type="long" minOccurs="0" default="1000" />
....
xml:
<root>
<name>AAA</name>
<interval />
...
getInterval() returns default value, but if 'interval' node doesn't exists
in xml (according to minOccurs="0" ) getInterval() returns 0. Is that
designed behavior?
Suppose it is. I do have isxxxSpecified() method to determne the existence
of the element in the document, but whether a way to get programmaticaly the
default value specified in the schema (to prevent its double maintenance in
the schema and in the code)?
Thanks,
Gennady

Re: element default value in generated classes
Posted by Radu Preotiuc-Pietro <ra...@bea.com>.
In XMLSchema, there is a difference between the element not being there
and the element being present, but with the default value. If your
application needs to perform the same action for both cases, you would
have to code this decision in your application. You can avoid
maintaining a separate default value by using the SchemaType API to get
the default value from Schema.
