Chapter 2. Setting up the software

classes derived from CEventProcessor is expected to process the raw event, and already unpacked

data producing new unpacked data. The event processor should return a kfTRUE if it succeeded well

enough that the event pipeline can continue to run or kfFALSE if SpecTcl should abort the event

pipeline and not histogram the event.

(12) When we implement the operator() function, we will have it hunt through the body of the raw

event for a packet that matches the id stored in m_nId member variable. When we ﬁnd that packet,

we’ll want to unpack it into our m_rawData tree parameter array. To make the code simpler to

understand, we plan to break off the actual unpacking of the packet into a utility function called

unpackPacket.

The next step is to actually implement the class. The implementation of this class is shown in the next

listing.

Example 2-4. Implementation of the MyEventProcessor class

#include <BufferDecoder.h>

#include <Event.h>

#include <iostream>

#include <TCLAnalyzer.h> // ➌

#ifdef HAVE_STD_NAMESPACE
