A CHOICE value specification causes a final static instance of the Java class generated for the CHOICE to be generated.
ASN.1 production:
<name> <ChoiceType> ::= elemname : <elemvalue>
Generated Java constants:
public static final <ChoiceType> <name> =
new <ChoiceType> (<ElemCode>,
new <ElemType> (<elemvalue>));
For example, consider the following declaration:
ChoiceType ::= CHOICE { oid OBJECT IDENTIFIER, id INTEGER }
value ChoiceType ::= id: 1
This would result in the following Java constant being generated:
public static final ChoiceType value =
new ChoiceType (ChoiceType._ID, new Asn1Integer(1));
