PropData & PropRegistry::operator[] ( const string & key ) [inline]
 

Allows set/get of properties data. This can e used in several ways:

  • for getting the value of a property: 
      string myPropValue = registry["myProp"];
  • for setting the value of a property (a new entry is added if the property did not exist inside the registry; if the entry existed, its value is reset to the new one). 
     vector<string> someDirs;
 someDirs.push_back("/");
 someDirs.push_back("/home/alec");
 registry["dirs"] = someDirs;
    The above creates a new entry (if not already presents) and sets its value to a vecotr of strings containing two strings.
  • adding values to a property: 
     string anotherOne = "/home/alec/tmp/stuff";
 vector<string> andSomeMore;
 registry["dirs"] << anotherOne;
 registry["dirs"] << andSomeMore;
 registry["more_dirs"] << "and" << "even" << "more" << registry["dirs"];
    The above codes makes use of the "<<" operator of the PropData. Node that on the last line the entry "some_more_dirs" is created "on the fly". Also, the last part of the ilne shows that properties can be appended to each other.
Note:
However, once a property is created, its kind (string/bool/int/float) gets set and an attempt to append some other kind of data via "<<" will fail with a bad_cast exception. The kind of the property can be changed, but only by re-setting it (using the "=" operator).
