<para>Parses a header of the form:</para>
<para><verbatim>  | access code | pkt len | pkt len | payload |
</verbatim></para>
<para>This is implemented as a state machine that starts off searching for the access code. Once found, the access code is used to find the start of the packet and the following header. This default header encodes the length of the payload a 16 bit integer twice. The state machine finds the header and checks that both payload length values are the same. It then goes into its final state that reads in the payload (based on the payload length) and produces a payload as a PMT u8 vector of packed bytes.</para>

<para>A vector of pmt::dicts to hold any meta data or info about the PDU. When parsing the header, the formatter can add info from the header into this dict.

<para>Used to handle the default packet header.</para>
<para>See the parent class <ref refid="classgr_1_1digital_1_1header__format__base" kindref="compound">header_format_base</ref> for details of how these classes operate.</para>
<para>The default header created in this base class consists of an access code and the packet length. The length is encoded as a 16-bit value repeated twice:</para>
<para><verbatim>  | access code | hdr | payload |
</verbatim></para>
<para>Where the access code is &lt;= 64 bits and hdr is:</para>
<para><verbatim>  |  0 -- 15 | 16 -- 31 |
  | pkt len  | pkt len  |
</verbatim></para>
<para>The access code and header are formatted for network byte order.</para>
<para>This header generator does not calculate or append a CRC to the packet. Use the CRC32 Async block for that before adding the header. The header&apos;s length will then measure the payload plus the CRC length (4 bytes for a CRC32).</para>
<para>The default header parser produces a PMT dictionary that contains the following keys. All formatter blocks MUST produce these two values in any dictionary.</para>
<para><itemizedlist>
<listitem><para>&quot;payload symbols&quot;: the number of symbols in the payload. The payload decoder will have to know how this relates to the number of bits received. This block knows nothing about the payload modulation or the number of bits/symbol. Use the <ref refid="classgr_1_1digital_1_1header__format__counter" kindref="compound">gr::digital::header_format_counter</ref> for that purpose.</para>
