  - toASN1Primitive
```
public ASN1Primitive toASN1Primitive()
```
    Produce an object suitable for an ASN1OutputStream.
```
  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 2^m 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 interface ASN1Encodable
    
    Specified by:
    
    toASN1Primitive in class ASN1Object
    
    Returns:
    
    a primitive representation of this object.
