66 * @short A helper class for element and group reference resolving.
68 * For easy resolving of element and group references, we have this class
69 * that can be used as a place holder for the real element or group
70 * object it is referring to.
71 * So whenever the parser detects an element or group reference, it creates
72 * a XsdReference and returns it instead of the XsdElement or XsdModelGroup.
73 * During a later phase, the resolver will look for all XsdReferences
74 * in the schema and will replace them with their referring XsdElement or
75 * XsdModelGroup objects.

80 class XsdReference : public XsdTerm
83 typedef QExplicitlySharedDataPointer<XsdReference> Ptr;
86 * Describes the type of the reference.
90 Element, ///< The reference points to an element.
91 ModelGroup ///< The reference points to a model group.
95 * Returns always @c true, used to avoid dynamic casts.
97 virtual bool isReference() const;
100 * Sets the @p type of the reference.
104 void setType(Type type);
107 * Returns the type of the reference.
112 * Sets the @p name of the referenced object.
114 * The name can either be a top-level element declaration
115 * or a top-level group declaration.

120 * Returns the name of the referenced object.
