XMLMember QGpCoreTools::GoogleEarthKML::xml_member

(

XML_MEMBER_ARGS

)

[protected, virtual]

Re-implement this function to offer XML restore (children and properties) support to your class.

From tag and map (with contains the attibute value) return a unique identifier under the format of a XMLMember. XMLMember is initialized with 3 types of contructors:

• An integer: id number of a property
• A XMLClass * : a child of this object identified by tag
• Default constructor: error, unknow child or property

Map of attributes can be inspected in this way (can be achived also in xml_setProperty()):

    static const QString tmp("childrenName");
    XMLRestoreAttributeIterator it=map.find(tmp);
    if(it!=map.end()) {
      // found attribute "childrenName"
    }

If the map of attributes is not used:

    Q_UNUSED(attributes);
    if(tag=="x1") return XMLMember(0);
    else if(tag=="y1") return XMLMember(1);
    else if(tag=="x2") return XMLMember(2);
    else if(tag=="y2") return XMLMember(3);
    else return XMLMember(XMLMember::Unknown);

Arithmetic operations + and - apply to XMLMember to avoid confusion of property id numbers between inherited objects. Offset 3 corresponds to the number of properties defined in this object.

    if(tag=="anInteger") return XMLMember(0);
    else if(tag=="aString") return XMLMember(1);
    else if(tag=="aDouble") return XMLMember(2);
    return AbstractLine::xml_member(tag, attributes, context)+3;

For the arguments of this function use Macro XML_MEMBER_ARGS.

Reimplemented from QGpCoreTools::XMLClass.

References TRACE, and QGpCoreTools::XMLMember::Unknown.

  {
    TRACE;
    Q_UNUSED(attributes);
    Q_UNUSED(context);
    if(tag=="Document") {

    } else return XMLMember(XMLMember::Unknown);
  }
