  - ### Constructor Detail

    - #### X9FieldElement

          public X9FieldElement(ECFieldElement f)

  - ### Method Detail

    - #### getValue

          public ECFieldElement getValue()

    - #### toASN1Primitive

          public ASN1Primitive toASN1Primitive()

            FieldElement ::= OCTET STRING

      1. if q is an odd prime then the field element is processed as an Integer and converted to an octet string according to x 9.62 4.3.1.
      2. if q is 2m then the bit string contained in the field element is converted into an octet string with the same ordering padded at the front if necessary.

      Specified by:
        `toASN1Primitive` in class `ASN1Object`
      Returns:
        a primitive representation of this object.
