Parse (unmarshal) a ticket flag from a DER input stream. This form parsing might be used when expanding a value which is part of a constructed sequence and uses explicitly tagged type.
Params:
  • data – the Der input stream value, which contains one or more marshaled value.
  • explicitTag – tag number.
  • optional – indicate if this data field is optional
Throws:
  • Asn1Exception – on error.
Returns:an instance of TicketFlags.
