TEntryListArray Class Reference
TTree

A list of entries and subentries in a TTree or TChain.

TEntryListArray is an extension of TEntryList, used to hold selected entries and subentries (sublists) for when the user has a TTree with containers (vectors, arrays, ...).

Usage with TTree::Draw to select entries and subentries

To fill a list elist

tree->Draw(">> elist", "x > 0", "entrylistarray");`

To use a list to select entries and subentries

tree->SetEntryList(elist);
tree->Draw("y");
tree->Draw("z");

Its main purpose is to improve the performance of a code that needs to apply complex cuts on TTree::Draw multiple times. After the first call above to TTree::Draw, a TEntryListArray is created and filled with the entries and the indices of the arrays that satisfied the selection cut (x > 0). In the subsequent calls to TTree::Draw, only these entries / subentries are used to fill histograms.

About the class

The class derives from TEntryList and can be used basically in the same way. This same class is used to keep entries and subentries, so there are two types of TEntryListArray's:

  1. The ones that only hold subentries
    • fEntry is set to the entry# for which the subentries correspond
    • fSubLists must be 0
  2. The ones that hold entries and eventually lists with subentries in fSubLists.
    • fEntry = -1 for those
    • If there are no sublists for a given entry, all the subentries will be used in the selection

Additions with respect to TEntryList

  1. Data members:
    • fSubLists: a container to hold the sublists
    • fEntry: the entry number if the list is used to hold subentries
    • fLastSubListQueried and fSubListIter: a pointer to the last sublist queried and an iterator to resume the loop from the last sublist queried (to speed up selection and insertion in TTree::Draw)
  2. Public methods:
    • Contains, Enter and Remove with subentry as argument
    • GetSubListForEntry: to return the sublist corresponding to the given entry
  3. Protected methods:
    • AddEntriesAndSubLists: called by Add when adding two TEntryList arrays with sublists
    • ConvertToTEntryListArray: convert TEntryList to TEntryListArray
    • RemoveSubList: to remove the given sublist
    • RemoveSubListForEntry: to remove the sublist corresponding to the given entry
    • SetEntry: to get / set a sublist for the given entry

kOnlyPrepStep 

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer.

This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock). To take advantage of this feature the class needs to overload TObject::Write and use this enum value accordingly. (See TTree::Write and TObject::Write) Do not use, this feature will be migrate to the Merge function (See TClass and TTree::Merge)

Member Function Documentation

◆ AbstractMethod()

void TObject::AbstractMethod ( const char * method) const
inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning
This interface is a legacy function that is no longer recommended to be used by new development code.
Note
The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

protectedvirtual

The method that really adds two entry lists with sublists If lists are split (fLists != 0), look for the ones whose trees match and call the method for those lists.

Add first the sublists, and then use TEntryList::Add to deal with the entries

Definition at line 186 of file TEntryListArray.cxx.

◆ AddSubList()

void TEntryList::AddSubList ( TEntryList * elist)
inherited

Add a sub entry list to the current list.

Parameters
[in]elistan entry list that should be added as a sub list of this list.

This function is specifically targeted at situations where there is a global TEntryList that should hold one or more sub TEntryList objects. For example, if one wants to create a one to one mapping between the sub entry lists and the trees in the files that make a TChain. Note that in such cases this configuration of the entry list should be used in pair with the option "sync" of the function TChain::SetEntryList

// Create a TChain with two files. Each contains a tree with 20 entries
TChain chain{"entries"};
chain.Add("file_20entries_1.root");
chain.Add("file_20entries_2.root");
// Create a global, empty TEntryList.
TEntryList elists;
// Create two entry lists. Each one will be referring to a different tree in the chain
TEntryList elist1{"","","entries","file_20entries_1.root"};
TEntryList elist2{"","","entries","file_20entries_2.root"};
// Select the first ten entries from the first tree and all entries from the second
for(auto entry = 0; entry < 10; entry++){
elist1.Enter(entry);
}
for(auto entry = 0; entry < 20; entry++){
elist2.Enter(entry);
}
// Add sub entry lists to the global list
elists.AddSubList(&elist1);
elists.AddSubList(&elist2);
// Set the entry list in the chain. Note the usage of option "sync"
chain.SetEntryList(&elists, "sync");

◆ CheckedHash()

ULong_t TObject::CheckedHash ( )
inlineinherited

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.

The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();

(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

◆ Hash()

ULong_t TNamed::Hash ( ) const
inlineoverridevirtualinherited

Return hash value for this object.

Note: If this routine is overloaded in a derived class, this derived class should also add

ROOT::CallRecursiveRemoveIfNeeded(*this)
ROOT::CallRecursiveRemoveIfNeeded
void CallRecursiveRemoveIfNeeded(TObject &obj)
call RecursiveRemove for obj if gROOT is valid and obj.TestBit(kMustCleanup) is true.
Definition TROOT.h:406

Otherwise, when RecursiveRemove is called (by ~TObject or example) for this type of object, the transversal of THashList and THashTable containers will will have to be done without call Hash (and hence be linear rather than logarithmic complexity). You will also see warnings like

Error in <ROOT::Internal::TCheckHashRecursiveRemoveConsistency::CheckRecursiveRemove>: The class SomeName overrides
TObject::Hash but does not call TROOT::RecursiveRemove in its destructor.

◆ HasInconsistentHash()

Bool_t TObject::HasInconsistentHash ( ) const
inlineinherited

Return true is the type of this object is known to have an inconsistent setup for Hash and RecursiveRemove (i.e.

missing call to RecursiveRemove in destructor).

Note: Since the consistency is only tested for during inserts, this routine will return true for object that have never been inserted whether or not they have a consistent setup. This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

◆ Write() [2/2]

Int_t TObject::Write ( const char * name = nullptr,
Int_t option = 0,
Int_t bufsize = 0 ) const
virtualinherited

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

  • Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
  • The TBuffer object is filled via the class::Streamer function.
  • If the file is compressed (default) a second buffer is created to hold the compressed buffer.
  • Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
  • The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.
