Detailed Description

template<typename Val, typename Alloc = std::allocator< Val >>
class gum::List< Val, Alloc >

Generic doubly linked lists.

List enables fast and safe manipulation of chained lists. Unless the elements are rvalues, the insertions of new elements into the lists are ALWAYS performed by copy, i.e., each time we add a new element X to the List, a copy of X is actually created and this very copy is stored into the list. For rvalues, move operations are performed.

The List iterators are implemented so as to avoid segmentation faults when elements of the list are deleted while some safe iterators are pointing on them. Moreover they ensure that, when elements are removed from a List, iterators on that list will never access these elements (which is not the case for the iterators in the C++ standard library). Note that this guarantee is ensured at low cost as experimental results show that List and ListIterator are as efficient as their STL counterparts. However, this guarantee can hold only if List is aware of all of the iterators pointing to it: thus, when List erases one element, it can parse the list of its iterators and update those that point toward the now deleted element. When parsing elements without removing any element, you can use unsafe iterators instead of safe ones because they are slightly faster. But those will most certainly segfault if they perform some operations on deleted elements.

Usage example:

// creation of an empty list
List<int> list1;
List<int> list2 { 3, 4, 5 }; // initializer list

// adding elements to the list
list1.pushFront (23);
list1.pushBack (10);
list1 += 25;
list1.insert (12);

// getting the second element of the list
cerr << "10 = " << list1[1] << endl;

// getting the first and last elements
cerr << "first = " << list1.front() << " last = " << list1.back() << endl;

// get the number of elements in the list
cerr << "number of elements = " << list1.size () << endl;

// display the content of the list
cerr << list1 << endl;

// copy the list
List<int> list2 = list1, list3;
list3 = list1;

// delete the second element from the list
list1.erase (1);

// delete the first and last elements
list1.popFront ();
list1.popBack ();

// delete element whose value is 25
list1.eraseByVal (25);

// check whether the list is empty
if (list1.empty()) cerr << "empty list" << endl;

// remove all elements from the list
list1.clear ();

// parse all the elements of a list using unsafe iterators
for (List<int>::iterator iter = list2.begin();
     iter != list2.end(); ++iter)
  cerr << *iter << endl;
for (List<int>::iterator iter = list2.rbegin();
     iter != list2.rend(); --iter)
  cerr << *iter << endl;
for (List<int>::const_iterator iter = list2.cbegin();
     iter != list2.cend(); ++iter)
  cerr << *iter << endl;
for (List<int>::const_iterator iter = list2.crbegin();
     iter != list2.crend(); --iter)
  cerr << *iter << endl;

// parse all the elements of a list using safe iterators
for (List<int>::iterator_safe iter = list2.beginSafe();
     iter != list2.endSafe(); ++iter)
  cerr << *iter << endl;
for (List<int>::iterator_safe iter = list2.rbeginSafe();
     iter != list2.rendSafe(); --iter)
  cerr << *iter << endl;
for (List<int>::const_iterator_safe iter = list2.cbeginSafe();
     iter != list2.cendSafe(); ++iter)
  cerr << *iter << endl;
for (List<int>::const_iterator_safe iter = list2.crbeginSafe();
     iter != list2.crendSafe(); --iter)
  cerr << *iter << endl;

// use an iterator to point the element we wish to erase
List<int>::iterator_safe iter = list2.beginSafe();
List2.erase ( iter );
List<int>::iterator iter2 = list2.begin() + 4; // 5th element of the list
iter2 = iter + 4;

// map a list into another list (assuming function f is defined as
// float f (int x) { return (2.5 * x); } )
List<float> flist = list2.map (f);

__erase()

template<typename Val, typename Alloc >

Removes an element from a chained list.

If parameter bucket is equal to 0, then the method does not perform anything, else the bucket is deleted. In the latter case, no test is ever performed to check that the bucket does actually belong to the List. The method runs in constant time.

Parameters

bucket

A pointer on the bucket in the chained list we wish to remove.

Returns the bucket corresponding to a given value.

Actually, this is the first bucket of value val encountered in the list, if any, that is returned. If the element cannot be found, 0 is returned. This method enables fast removals of buckets. It runs in linear time.

Comparisons between Val instances are performed through == operators.

Parameters

val	The value of the element the bucket of which we wish to return.

Returns

Returns the bucket corresponding to a given value.

template<typename Val, typename Alloc = std::allocator< Val >>

template<typename... Args>

Val& gum::List< Val, Alloc >::emplace	(	const const_iterator &	iter,

	)

Emplace a new element before a given iterator.

Emplace is a method that allows to construct directly an element of type Val by passing to its constructor all the arguments it needs. The first element of the list is at pos 0. After the insert, the element is placed precisely at pos if pos is less than the size of the list before insertion, else it is inserted at the end of the list.

Parameters

iter	The position in the list
args	The arguments passed to the constructor

Returns

Returns a reference on the copy inserted into the list.

Emplace a new element before a given safe iterator.

Emplace is a method that allows to construct directly an element of type Val by passing to its constructor all the arguments it needs. The first element of the list is at pos 0. After the insert, the element is placed precisely at pos if pos is less than the size of the list before insertion, else it is inserted at the end of the list.

Parameters

iter	The position in the list.
args	the arguments passed to the constructor.

Returns

Returns a reference on the copy inserted into the list.

end() [1/2]

template<typename Val , typename Alloc >

INLINE const ListIterator< Val > & gum::List< Val, Alloc >::end ( )

noexcept

Returns an unsafe iterator pointing to the end of the List.

Unsafe iterators are a little bit faster than safe iterators and they consume less memory. However, if the element they point to is erased, their dereference or their increment/decrement will produce a mess, probably a segfault. You should use them only when performance is an issue and if you are sure that they will never point to an element erased.

Returns

Returns an unsafe iterator pointing to the end of the List.

Returns a safe iterator pointing to the end of the List.

Safe iterators are iterators whose state is updated by the list when the element they point to is erased. As such, in this case, they can throw an exception when we try to derefence them and they are able to perform a valid ++ or – step.

Ceturns a safe iterator pointing to the end of the List.

Checks whether two lists are different (different elements or orders).

This method runs in time linear in the number of elements of the list.

Returns true if src and this gum::List are identical.

Template Parameters

operator+=() [1/2]

template<typename Val, typename Alloc >

INLINE Val & gum::List< Val, Alloc >::operator+=

Inserts a new element at the end of the list (alias of pushBack).

This enables writing code like list += xxx; to add element xxx to the list.

Warning

Note that val is not actually inserted into the list. Rather, it is a copy of val that is inserted.

Parameters

val	Tha value inserted int the list.

Returns

Returns a reference on the copy inserted into the list.

operator=() [1/4]

template<typename Val, typename Alloc>

INLINE List< Val, Alloc > & gum::List< Val, Alloc >::operator=

(

const List< Val, Alloc > &

)

Copy operator.

The new list and that which is copied do not share the elements: the new list contains new instances of the values stored in the list to be copied. Of course if these values are pointers, the new values point toward the same elements. The List on which the operator is applied keeps its iterator's list. Of course, if it previously contained some elements, those are removed prior to the copy. This operator runs in linear time.

Warning

If the current List previously contained iterators, those will be resetted to end()/rend().

Parameters

src	the list the content of which will be copied into the current List.

Returns

Returns this gum::List.
