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));
