    • getDslWeight

      public int getDslWeight()
      Description copied from interface: DslElement
      The weight can be used to find an optimal program in a set of valid programs. "Optimal" is subjective and can go into different directions. Some examples include:
      • Weight by how expensive a DSL element is to execute.
        Weight by how likely a DSL element is to be part of a generic full program. A ConstantPosition generally is less generic. Thus, the user has to specify their intent more often to finish their wrangling task.
      • Specified by:
      getDslWeight in interface DslElement
      Returns:
      the weight of the DSL element
