  • Method Details

    • isCanonical

      public abstract boolean isCanonical()
      Description copied from class: ACell
      Returns true if this Cell is in a canonical representation for message writing. Non-canonical objects may be used on a temporary internal basis, they must always be converted to canonical representations for external use (e.g. Encoding).
      Overrides:
      isCanonical in class APrimitive
      Returns:
      true if the object is in canonical format, false otherwise

    • toCanonical

      public abstract AInteger toCanonical()
      Description copied from class: ACell
      Converts this Cell to its canonical version. Must return this Cell if already canonical, may be O(n) in size of value otherwise.
      Overrides:
      toCanonical in class APrimitive
      Returns:
      Canonical version of Cell

      Incremented value

    • signum

      public abstract CVMLong signum()
      Description copied from class: ANumeric
      Gets the signum of this numerical value. Will be -1, 0 or 1 for Longs, -1.0, 0.0 , 1.0 or ##NaN for Doubles.
