@Target(value=FIELD) @Retention(value=RUNTIME) public @interface ASN1Element
Indicates that a field is an element of a structured type.
If an @ASN1Element annotation is present on a field, the field is
treated as a component of a SEQUENCE type or a SET type. A field annotated as
@ASN1Element must be declared as public non-final
non-static, and the type shall be a sub-class of ASN1Type.
The value parameter represents an order of appearance of a field in
an ASN.1 type definition. The value parameter must be set even if a
container type is a SET type. It will be used by the automatic
tagging process.
For example, following ASN.1 definition :
Sample ::= SET {
number INTEGER,
bool BOOLEAN OPTIONAL }
can be translated as :
public class Sample extends SET {
@ASN1ElementType(0)
public INTEGER number;
@ASN1ElementType(value = 1, optional = true)
public BOOLEAN bool;
}
