typedef QMultiMap<QString, QString> QgsSmartConditionMap

A multimap to hold the smart group conditions as constraint and parameter pairs.

Both the key and the value of the map are QString. The key is the constraint of the condition and the value is the parameter which is applied for the constraint.

The supported constraints are: tag -> symbol has the tag matching the parameter !tag -> symbol doesn't have the tag matching the parameter name -> symbol has a part of its name matching the parameter !name -> symbol doesn't have any part of the name matching the parameter

Example Usage: QgsSmartConditionMap conditions; conditions.insert( "tag", "red" ); // adds the condition: Symbol has the tag red conditions.insert( "!name", "way" ); // add the condition: Symbol doesn't have any part of its name matching way

Note

This is a Multimap, which means it will contain multiple values for the same key.
