Prolog class

The Prolog class represents the initial 256-byte section of a communications trace for a LAN line description. The Prolog contains general information about the trace, such as start and end times, number of bytes collected, and so on. Use the Prolog class to retrieve information from this section of trace, which you can then print, display, filter, or process in some other way.

The Prolog class provides methods that allow you to perform a variety of actions that include the following:

• Retrieve values from the fields of the prolog, such as the trace description, Ethernet Type, data direction, IP address, and so on
• Return a formatted String that contains all the fields of the prolog
• Test the prolog fields for invalid data

Example

The following example shows how you can use many of the commtrace classes, including the Prolog class, to display trace information to your monitor:
