Class Description

HLdSource

  Base class for a "data source" which delivery LMD data.
  The derived class HldFileSource reads the data from a file on disk and
  the derived class HldRemoteSource getrs the data directly from the
  Data Adquisition.

  The data in the file need to be unpacked. The user must specify the list
  of unpackers (see HldUnpack) to use, this way the user can select which
  parts of the data will be retrieved. That also give support to the case of
  LMD files not containing all the possible types of data (Rich data,
  Mdc data...)

  An example would be:
  HLmdFileSource *lmdSource=new HLmdFileSource();
  lmdSource->addUnpacker(new HRichUnpacker);

  This way you only get the Rich data in the files specified in the runtime
  database

Destructor for a LMD data source

 adds an unpacker to the list of unpackers for a LMD source

Calls the init() function for each unpacker.

Calls the reinit() function for each unpacker.

Calls the init() function for each unpacker.

Decodes the event's header

 dump the whole evt on the screen

 Scan the event.
printf("*******************************************************************n");
