THashList Class Reference

THashList implements a hybrid collection class consisting of a hash table and a list to store TObject's.

The hash table is used for quick access and lookup of objects while the list allows the objects to be ordered. The hash value is calculated using the value returned by the TObject's Hash() function. Each class inheriting from TObject can override Hash() as it sees fit.

void THashList::AddFirst ( TObject obj)
virtual
void THashList::AddFirst ( TObject obj,
Option_t opt 
)
virtual

Add object at the beginning of the list and also store option.

Storing an option is useful when one wants to change the behaviour of an object a little without having to create a complete new copy of the object. This feature is used, for example, by the Draw() method. It allows the same object to be drawn in different ways.

Float_t THashList::AverageCollisions ( ) const

Return the average collision rate.

The higher the number the longer the linked lists in the hashtable, the slower the lookup. If the number is high, or lookup noticeably too slow, perform a Rehash().

Definition at line 159 of file THashList.cxx.

void THashList::Clear ( Option_t option = "")
virtual
void THashList::Delete ( Option_t option = "")
virtual

Remove all objects from the list AND delete all heap based objects.

If option="slow" then keep list consistent during delete. This allows recursive list operations during the delete (e.g. during the dtor of an object in this list one can still access the list to search for other not yet deleted objects).

private
void THashList::RecursiveRemove ( TObject obj)
virtual

Remove object from this collection and recursively remove the object from all other objects (and collections).

This function overrides TCollection::RecursiveRemove that calls the Remove function. THashList::Remove cannot be called because it uses the hash value of the hash table. This hash value is not available anymore when RecursiveRemove is called from the TObject destructor.

void THashList::Rehash ( Int_t  newCapacity)

Rehash the hashlist.

If the collision rate becomes too high (i.e. the average size of the linked lists become too long) then lookup efficiency decreases since relatively long lists have to be searched every time. To improve performance rehash the hashtable. This resizes the table to newCapacity slots and refills the table. Use AverageCollisions() to check if you need to rehash.
