property-set Class for storing a set of properties. class property-set { rule raw ( ) rule str ( ) rule propagated ( ) rule add ( ps ) rule add-raw ( properties * ) rule refine ( ps ) rule get ( feature ) } There is 1<->1 correspondence between identity and value. No two instances of the class are equal. To maintain this property, the 'property-set.create' rule should be used to create new instances. Instances are immutable. raw Property Set Method rule raw ( ) Returns a Jam list of the stored properties. str Property Set Method rule str ( ) Returns the string repesentation of the stored properties. propagated Property Set Method rule propagated ( ) Returns a property-set containing all the propagated properties in this property-set. add Property Set Method rule add ( ps ) Returns a new property-set containing the union of the properties in this property-set and in ps. If ps contains non-free properties that should override the values in this object, use refine instead. add-raw Property Set Method rule add-raw ( properties * ) Link add, except that it takes a list of properties instead of a property-set. refine Property Set Method rule refine ( ps ) Refines properties by overriding any non-free and non-conditional properties for which a different value is specified in ps. Returns the resulting property-set. get Property Set Method rule get ( feature ) Returns all the values of feature.
