Detailed Description

template<class KEY, class VALUE, class KEYCOMPARE = std::less<const KEY>, class ALLOCATOR = std::allocator<std::pair<KEY, VALUE>>>
class GaudiUtils::VectorMap< KEY, VALUE, KEYCOMPARE, ALLOCATOR >

A bit modified version of 'Loki::AssocVector' associative vector from Loki library by Andrei Alexandrescu.

The number of "non-const" operations is reduced, e.g. all non-const iterators are not exported, therefore it is almost impossible e.g. externally re-sort the underlying sorted container.


The nominal CPU performance:

Container insertion: O(N) Container look-up: O(log(N)) (a'la std::map, but a bit faster)

It could be used as a "light" and good alternative for std::map associative container, in the case of relatively rare insertion and frequent look-up.

Due to helper base class Gaudi::Utils::MapBase, this class is "python-friendly", and one can perform all python manipulaitons in intuitive way:

>>> m = ... ## get the map
>>> print m ## print the map a'la python class dict
...
>>> for key in m : print key, m[key] ## iteration over the map
...
>>> for key,value in m.iteritems() : print key, value
...
>>> keys = m.keys() ## get the list of keys
>>> values = m.values () ## get the list of values
>> items = m.items () ## get the list of items
>>> if 'one' in m ## check the presence of the key in map
>>> v = m.get(key', None) ## return m[key] for existing key, else None
>>> del m[key] ## erase the key form the map
>>> value m[key] ## unchecked access through the key
...
>>> m.update( key, value ) ## update/insert key/value pair
Attention
The syntax can be drastically simplified, if one redefines the setitem attribute:
>>> type(m).__setitem__ = Gaudi.Utils.MapBase.__setitem__
>>> m[key] = value ## much more intuitive semantics for key insertion

In a similar way __getitem__ and __delitem__ methods can be redefind

To avoid the unnesessary expansion of dictionaries it is highly recommended to exclude from dictionary the following methods:

  • lower_bound
  • upper_bound
  • equal_range
  • insert

insert the (key,value) pair into the container

Attention

It is STL-compliant behavior for associative containers.

V val1 = ... ;
V val2 = ... ;
<< " Before insert: " << m[key] // should be: V()
<< std::end ;
// insert the value into the map:
const bool inserted1 = m.insert( key , val1 ).second ;

<< " 2nd insert: "
<< Gaudi::Utils::toString( inserted2 ) // should be: "False"
<< " value: " << m[key] // should be: val1

Parameters

Returns
