    • addElement

      private void addElement(SET.Template.Element e)

      private void insertElementAt(SET.Template.Element e, int index)

    • addElement

      public void addElement(ASN1Template t)
      Adds a sub-template to the end of this SET template. For example, if the ASN.1 included: 
       MySet ::= SET {
      item        SubType,
      ... }
      the "item" element would be added to the MySet template with: 
       mySet.addElement(new SubType.Template());
      Parameters:
      t - Sub-template.

    • insertElementAt

      public void insertElementAt(ASN1Template t, int index)
      Inserts the template at the given index.
      Parameters:
      t - Sub-template.
      index - Index.

    • addElement

      ... }
      the "item" element would be added to the MySet template with:
