Detailed Description

template<typename LOCATION, typename VALUE, uint64_t TYPE, bool REPEATABLE = false, typename DECODER_TAG = VALUE, typename ENCODER_TAG = VALUE>
class ndn::lp::FieldDecl< LOCATION, VALUE, TYPE, REPEATABLE, DECODER_TAG, ENCODER_TAG >

Declare a field.

Template Parameters

LOCATION	a tag that indicates where the field is in an LpPacket.
VALUE	type of field value.
TYPE	TLV-TYPE number of the field.
REPEATABLE	whether the field is repeatable.
DECODER_TAG	selects a specialization of DecodeHelper.
ENCODER_TAG	selects a specialization of EncodeHelper.
