This class provides an event processor that encapsulates a callout object. The event processor does data format specific extraction of information from items and passes them to methods provided by its call out object.
The callout object methods are descried by the base class for such
classes: CAnalysisBase.
The methods provided by all event processors are not documented
in this manpage. See the CEventProcessor
manpage for those. We only document the public methods that
are provided for use by the callout objects.
CAnalysisEventProcessor(CAnalysisBase* pProcessor, void* pClientData = = 0);
The constructor is parameterized by a pointer to the
callback object the event processor will use. The object
pointed to by this pointer must have program lifetime.
The optional pClientData parameter
provides the ability to pass arbitrary data to the
callbacks.
CEvent* getEvent();
Returns a pointer to the base CEvent object that is filled
in when a physics event is being processed. This pointer
is meaningless unless called from the callout object's
onEvent method.
CBufferDecoder* getDecoder();
Gets a pointer to the buffer decoder object in use by the analysis pipeline. This pointer is valid from all callbacks.
CAnalyzer* getAnalyzer();
Gets a pointer to the analyzer object in use by the analysis pipeline. This pointer is valid from all callbacks.
CAnalysisEventProcessor passes a parameter
to callbacks that is of type CAnalysisEventProcessor::ClientData.
This data type is a struct with the following members.
s_pUserData
The value of the pClientData
parameter of the object's constructor.
s_pCallerPointer to the object itself (e.g. the event processor's this pointer).
