Detailed Description

Used to quickly find the Events, Lumis, and Runs in a single ROOT format data file and step through them in the desired order.

A list of the most important functions that a client would use directly follows. There are detailed comments below with the declaration of each function.

The begin and end functions are used to start and stop an iteration loop. An argument to the iterator constructor determines the order of iteration.

The functions findPosition, findEventPosition, findRunPosition, and findLumiPosition are used to navigate directly to specific runs, lumis, and events.

The functions mentioned above return an object of type IndexIntoFileItr. The IndexIntoFileItr class has member functions which allow one to navigate forward and backward through the runs, lumis, and events in alternative ways. See more comments with the declaration of each public member function in IndexIntoFileItr.

The iterator will know what the current item is (as one would expect). This could be a run, lumi, or event. It knows more than that though, it knows all three as is explained below.

In the run state, IndexIntoFileItr knows which lumi will be processed next after the run and also which event will be processed after the lumi. These may not be the first ones in the run if the skip functions were used.

In the lumi state, the IndexIntoFileItr will always point at the last associated run and the next event to be processed after the lumi. This may not be the first event if the skip function was used.

In the event state, the IndexIntoFileItr will always point at the last corresponding run and also the last corresponding lumi.

There can be multiple run entries in a TTree associated with the same run number and ProcessHistoryID in a file. There can also be multiple lumi entries associated with the same lumi number, run number, and ProcessHistoryID. Both sorting orders will make these subgroups contiguous, but beyond that is up to the client (normally PoolSource, which passes them up to the EventProcessor) to deal with merging the multiple run (or lumi) entries together.

One final comment with regards to IndexIntoFileItr. This is not an STL iterator and it cannot be used with std:: algorithms. The data structures are complex and designed to optimize memory usage. It would be difficult or impossible implement an iterator that is STL compliant.

Here is a summary of the data structures in IndexIntoFile. The persistent data consists of two vectors.

processHistoryIDs_ is a std::vector<ProcessHistoryID> that contains the ProcessHistoryIDs with one element in the vector for each unique ProcessHistoryID. On output they are ordered as they first written out for each output file. On input they are ordered as they are first seen in each process. Note that each ProcessHistoryID is stored once in this separate vector. Everywhere else it is needed it stored as an index into this vector because the ProcessHistoryID itself is large and it would take more memory to store them repeatedly in the other vectors. Note that the ProcessHistoryID's referenced in this class are always the "reduced" ProcessHistoryID's, not the ProcessHistoryID of the full ProcessHistory. You cannot use them to directly access the ProcessHistory from the ProcessHistoryRegistry.

runOrLumiEntries_ is a std::vector<RunOrLumiEntry>. This vector holds one element per entry in the run TTree and one element per entry in the lumi TTree. When sorted, everything associated with a given run and ProcessHistoryID will be contiguous in the vector. These groups of elements will be sorted in the order they first appear in the input file. Within each of these groups the run entries come first in order, followed by the elements associated with the lumis. The lumis are also contiguous and sorted by first appearance in the input file. Within a lumi they are sorted by entry order. And each luminosity element corresponds to one contiguous sequence of Events in the Events TTree. Before we implemented concurrent processing of luminosity blocks that was the full story. After that it became more complicated because the sequence of events written to an output file that were associated with a particular luminosity block TTree entry might no longer be contiguous. Events from another concurrent luminosity block could get mixed in because with multiple events processing simultaneously, there is no longer any guarantee they will finish in the same order that they were read. This is handled by writing additional elements to the runOrLumiEntries_ vector, one for each contiguous block of events associated with a particular luminosity block. Only one of these vector elements will be associated with each entry in the luminosity block TTree and all the others will contain a TTree entry number that is invalid (note the one element with a valid entry might or might not be associated with a contiguous block of events). In the sort of elements related to a particular luminosity block, the entries with invalid entry numbers will come before the valid ones. (It has not happened yet as I am writing this, but a similar thing will likely occur for runs if/when we ever implement concurrent runs)

There are a number of transient data members also. The 3 most important of these are vectors. To save memory, these are only filled when needed.

runOrLumiIndexes_ is a std::vector<RunOrLumiIndexes>. There is a one to one correspondence between the elements of this vector and the elements of runOrLumiEntries_. The elements of this vector are sorted in numerical order using the ProcessHistoryID index, the run number, and the lumi number. This ordering allows iteration in numerical order and also fast lookup based on run number and lumi number. Each element also has indexes into the eventNumbers_ and eventEntries_ vectors which hold the information giving the event numbers and event entry numbers. Note this vector is initially formed in the identical order as runOrLumiEntries_ and then sorted with a stable sort. The fact that it is a stable sort means that within the subrange associated with a particular luminosity block the elements with an invalid TTree entry number come first and the later come the elements with a valid TTree entry number which are in order of TTree entry number.

eventNumbers_ is a std::vector containing EventNumber_t's. eventEntries_ is a std::vector containing EventEntry's. If filled, both vectors contain the same number of entries with identical event numbers sorted in the same order. The only difference is that one includes the entry numbers and thus takes more memory. Each element of runOrLumiIndexes_ associated with a luminosity block has the indexes necessary to find the range inside eventNumbers_ or eventEntries_ corresponding to its lumi. Within that range the elements are sorted by event number, which is used for the numerical order iteration and to find an event by the event number.

The details of the data structure are a little different when reading files written before release 3_8_0 (backward compatibility, see RootFile::fillIndexIntoFile for the details).

This data structure is optimized for low memory usage when there are large numbers of events. The optimal case would occur when there was was one run in a file, one luminosity block in that run and everything had the same ProcessHistoryID. If duplicate checking were off and the process simply iterated through the file in the default order, then only the persistent vectors would be filled. One vector would contain 2 elements, one for the run and the other for the lumi. The other vector would contain one element, the ProcessHistoryID. Even if there were a billion events, that would be all that would exist and take up memory. The data structure is not the optimal structure for a very sparse skim, but the overheads should be tolerable given the number of runs and luminosity blocks that should occur in CMS data.

Normally only the persistent parts of the data structure are filled in the output module. The output module fills them using two functions designed specifically for that purpose. The functions are addEntry and sortVector_Run_Or_Lumi_Entries.

There are some complexities associated with filling the data structure, mostly revolving around optimizations to minimize the per event memory usage. The client needs to know which parts of the data structure to fill. See the functions below named fixIndexes, setNumberOfEvents, setEventFinder, fillEventNumbers, fillEventEntries, and inputFileClosed.

Note that this class is not intended to be used directly by the average CMS user. PoolSource and PoolOutputModule are the main clients. Other executables that read ROOT format data files, but do not use PoolSource may also need to use it directly (FWLite, Fireworks, edmFileUtil ...). The interface is too complex for general use.

enum edm::IndexIntoFile::SortOrder

This enum is used to specify the order of iteration. In firstAppearanceOrder there are 3 sort criteria, in order of precedence these are:

1. firstAppearance of the ProcessHistoryID and run number in the file
2. firstAppearance of the ProcessHistoryID, run number and lumi number in the file
3. entry number

In numerical order the criteria are in order of precedence are:

1. processHistoryID index (which are normally in order of appearance in the process)
2. run number
3. lumi number
4. event number
5. entry number

void edm::IndexIntoFile::fillEventEntries

(

)

const

Fills a vector of objects that contain an event number and the corresponding TTree entry number for the event. Not filling it reduces the memory used by IndexIntoFile. As long as the event finder is still pointing at an open file this will automatically be called on demand (when the event numbers and entries are are needed). It makes sense for the client to fill this explicitly in advance if it is known that it will be needed, because in some cases this will prevent the event numbers vector from being unnecessarily filled (wasting memory). This vector will be needed when iterating over events in numerical order or looking up specific events. The entry numbers are needed if the events are actually read from the input file.

void edm::IndexIntoFile::fillEventNumbers

(

)

const

Fills a vector of event numbers. Not filling it reduces the memory used by IndexIntoFile. As long as the event finder is still pointing at an open file this will automatically be called on demand (when the event numbers are are needed). In cases, where the input file may be closed when the need arises, the client code must call this explicitly and fill the vector before the file is closed. In PoolSource, this is necessary when duplicate checking across all files and when doing lookups to see if an event is in a previously opened file. Either this vector or the one that also contains event entry numbers can be used when looking for duplicate events within the same file or looking up events in in the current file without reading them.

Find a run, lumi, or event. Returns an iterator pointing at it. The iterator will always be in numericalOrder mode. If it is not found the entry type of the iterator will be kEnd. If it is found the entry type of the iterator will always be kRun so the next thing to be processed is the run containing the desired lumi or event or if looking for a run, the run itself. If the lumi and event arguments are 0 (invalid), then it will find a run. If only the event argument is 0 (invalid), then it will find a lumi. If will look for an event if all three arguments are nonzero or if only the lumi argument is 0 (invalid). Note that it will find the first match only so if there is more than one match then the others cannot be found with this method. The order of the search is by processHistoryID index, then run number, then lumi number, then event entry. If searching for a lumi the iterator will advance directly to the desired lumi after the run even if it is not the first lumi in the run. If searching for an event, the iterator will advance to the lumi containing the run and then the requested event after run even if there are other lumis earlier in that run and other events earlier in that lumi.

Used by PoolSource to force the ProcessHistoryID indexes to be consistent across all input files. Currently this consistency is important when duplicate checking across all input files. It may be important for other reasons in the future. It is important this be called immediately after reading in the object from the input file, before filling the transient data members or using the indexes in any way.

void edm::IndexIntoFile::setEventFinder ( std::shared_ptr< EventFinder >  ptr ) const

inline

Calling this enables the functions that fill the event vectors to get the event numbers. It needs to be called before filling the events vectors This implies the client needs to define a class that inherits from EventFinder and then create one. This function is used to pass in a pointer to its base class.

Used by RootOutputModule after all entries have been added. This only works after the correct sequence of addEntry calls, because it makes some corrections before sorting. A std::stable_sort works in cases where those corrections are not needed.
