aggregate_properties_by_regexp selective class properties aggregation to an object using a regular expression voidaggregate_properties_by_regexp objectobject stringclass_name stringregexp boolexclude Aggregates properties from a class to an existing object using a regular expresion to match their names. The optional paramater exclude is used to decide whether the regular expression will select the names of class properties to include in the aggregation (i.e. exclude is &false;, which is the default value), or to exclude from the aggregation (exclude is &true;). The properties whose names start with an underscore character (_), which are considered private to the aggregated class, are always excluded.
