  • Field Details

  • Constructor Details

    • Expression

      public Expression(@Opt Location<XMLDocumentIdentifier> location)
      Constructor defined according to directive »C 0/..«.

      Parameters:
      location - is copied to field Expr0.location

    • Expression

      public Expression()
      Constructor with minimal set of arguments, is supplied automatically by the umod compiler, not explicitly by the user.
      (All object fields are set to their default values.)

  • Method Details

    • doclone

      public Expression doclone()
      Clones this object. Method never fails, since Cloneable is known to be implemented.

      Overrides:
      doclone in class Expr0
      Returns:
      a fresh copy.

    • format

      public Format format()
      Delivers a format object for pretty-printing by inheritance from some ancestor class.
      Specified by:
      format in interface Formattable
      Overrides:
      format in class Expr0
      Returns:
      a format that represents this object in a pretty-printable way

    • initFrom

      public Expression initFrom(Object o0)
      Copies values of all common fields from the argument. All fields of this class definition are copied, iff the argument is of this class. Then the superclass method is invoked with the same argument.
      Overrides:
      initFrom in class Expr0

    • get_canProduceEpsilon

      public boolean get_canProduceEpsilon()
      Generated by umod; model author's documentation MISSING.
      (This definition has been created by UMod from the source at SYSTEM "D2d.umod":35.5-32, see this pretty print.)
      Generated getter method.
      Returns:
      The current field value of type boolean(never null)

    • set_canProduceEpsilon

      public boolean set_canProduceEpsilon(boolean val)
      Generated by umod; model author's documentation MISSING.
      (This definition has been created by UMod from the source at SYSTEM "D2d.umod":35.5-32, see this pretty print.)
      Updates the (mutable) instance destructively.
      Parameters:
      val - the new value of type boolean(never null)
      Returns:
      whether a change (w.r.t. ==) did actually happen.
