Built-in Functions

Cardinality

• Syntax:

  Cardinality(enumerationlist)
  

• Returns:

  Integer value.

• Description:

  "Cardinality" returns the number of named constants in the enumeration list.

  Example:

  TYPE Components "Biological components " = ENUM { H2O, S_I, S_S, S_O, S_NO, S_NH, S_ND, S_ALK };
  OBJ NrOfComponents "The number of components" : Integer := Cardinality(Components);
  

  "NrOfComponents" has the value 8;

SelectByType

• Syntax:

  SelectByType(powerset_type, sel_type)
  

• Returns:

  Powerset.

• Description:

  Returns the subset of objects with type name "sel_type" within the set with signature "powerset_type".

  Example:

  {
    FOREACH Comp_Index IN {1 .. NrOfComponents}:
      state.FluxPerComponent[Comp_Index] =
        (SUMOVER In_Terminal IN {SelectByType(interface,InWWTPTerminal)}:
           In_Terminal[Comp_Index]) +
           (SUMOVER Out_Terminal IN {SelectByType(interface,OutWWTPTerminal)}:
             Out_Terminal[Comp_Index]);
  };
