Detailed Description

DAQ::DDAS::DDASHitUnpacker is capable of unpacking raw hits from DDAS files. Typical trace analysis may involve fitting traces to one or two pulses. This class extends the DDASHitUnpacker class to support access to the results of the fit which have been tacked on the back end of a hit by CDDASAnalyzer.cpp.

Member Function Documentation

const void * DAQ::DDAS::FitHitUnpacker::decode	(	const void *	p,
		DDASFitHit &	hit
	)

decode

• Determines the limits of the old style hit.
• Determines where, or if, there's an extension block.
• Unpacks the original hit using DDASHitUnpacker::unpack.
• Sets the extension if there is one.

  Parameters

  pRingItem	- points to the ring item to decode. For an event built fragment, this is normally the FragmentInfo's s_itemhdr pointer. Note the difference from DDASHitUnpacker which expects a pointer to the body.
  hit	- hit item that we will unpack.

  Returns

  Pointer just after the ring item.
