Storing Intra-Frame Data

The first step is to save the source and destination address in the IP decoder (IP.dec). The method used to save intraframe data is StoreIntraframeField, and it is used in a RETRIEVE clause on the field to be saved. The method name is followed by the intra-frame data name.

Here is a code fragment from the IP decoder, showing how the method is used to save the field values.

FIELD src_addr (Fixed 4 Byte)

RETRIEVE (StoreIntraframeField source_ip_address) (IPAddress) IN_SUMMARY Source 90 "Source Address"

FIELD dest_addr (Fixed 4 Byte)

RETRIEVE (StoreIntraframeField destination_ip_address) (IPAddress) IN_SUMMARY Destination 90 "Destination Address"
