Content Group Types

---

Classes generated for <xsd:sequence> or <xsd:all> complex types contain a series of public element declarations for each of the elements in the declaration. These are populated using either direct assignment or the methods available in the element type classes. If atomic types are used for elements, the primitive type itself is used in the generated class, not a class derived from the type. For example, if a sequence contains an element declared to be an <xsd:integer>, the OSINT32 type is used for the member variable.

Classes generated for the <xsd:choice> complex type will contain methods to get, set, or query each of the choice selection elements. The format of these methods is get_<name>, set_<name>, or is_<name> where <name> would be replaced with the actual element name as defined in the schema.

Content model groups that repeat (i.e. have a maxOccurs facet with a value greater than one) cause a class to be generated that is derived from the OSObjListClass base class. This class contains append methods for adding elements to the list. An example of what the append method looks like is given in the `Dynamic Memory Management' section above. This method allows memory ownership for the object being added to the list to be tranferred to the list object. Note that this can be done on a per-element basis making it possible to mix and match dynamic and static element declarations in a given list.
