Last change on this file since 11952 was 11952, checked in by abeham, 8 years ago

#2174:

  • Made encodingOperators hash set an ItemSet and private
  • Added a parameter that displays the operators of an encoding (fixedvalue showing a readonly version of the itemset)
  • Added protected methods to Encoding to add and remove operators
  • Adapted MultiEncodingView to derive from ParameterizedNamedItemView
  • Added name of MultiEncoding itself to list of forbidden names
