Detailed Description

template<typename T>
class Aleph::ArrayQueue< T >

Queue implemented with a single dynamic array.

ArrayQueue<T> represents a queue if elements of generic type T which is stored in single dynamic. In this queue, modifiying operations test arrays bounds.

The array is allocated with new operator and dynamically grows according to the size.

Note
If you are sure of knowing the bounds, then use FixedStack, which is faster because it does not perform bound checks,

void Aleph::FunctionalMethods< ArrayQueue< T > , T >::each ( size_t  pos,
size_t  slice,
Operation &  operation 
) const
inlineinherited

Traverse all the container and performs a mutable operation on each element.

mutable_for_each(operation) traverses the container and on each element item is performed operation(item).

operation could have the following signature:

void operation(T & item)

Be very careful with the fact that this method allows to modify the elements themselves, what could badly alter the internal state of container. This would be the case for heaps, binary trees and hash tables.

[in]<tt>operation</tt>to be done on each element.
Returns
an reference to this
Exceptions
anythingthat can throw operation

◆ emplace()

void Aleph::FunctionalMethods< ArrayQueue< T > , T >::emplace ( Args &&...  args)
inlineinherited

Appends a new element into the container by constructing it in-place with the given args.

emplace(args) tries to match a constructor T(args). If this exists, then this is constructed in-place and directly forwarded to the method append() of container. If all on the container and T` is adequately done, then the object is constructed once time, successively forwarded and at its target place in the container is moved, avoiding thus unnecessary copies.

Note
The semantic of append depends of container. In general, this has some sense for lists and arrays and it means insertion at the end of sequence. On other type of container append() is equivalent to insert().
Parameters
[in]argsvariadic arguments list
Exceptions
bad_allocif there is no enough memory

void Aleph::FunctionalMethods< ArrayQueue< T > , T >::emplace_ins ( Args &&...  args)
inlineinherited

Insert a new element into the container by constructing it in-place with the given args.

emplace_ins(args) tries to match a constructor T(args). If this exists, then this is constructed in-place and directly forwarded to the method insert() of container. If all on the container and T` is adequately done, then the object is constructed once time, successively forwarded and finally, at its target place in the container, is moved, avoiding thus unnecessary copies.

Note
The semantic of insert() depends of container. In general, this has some sense for lists and arrays and it means insertion at the beginning of sequence. On other type of container append() is equivalent to insert().
Parameters
[in]argsvariadic arguments list
Exceptions
bad_allocif there is no enough memory

◆ equal_to()

bool Aleph::EqualToMethod< ArrayQueue< T > >::equal_to ( const ArrayQueue< T > &  r) const
inlinenoexceptinherited

Test if elements of this are exactly contained in another container.

This method serves for testing if two containers contain the same elements. First, the container sizes are tested for equality. If they have the same size, then the testing is done by traversing this. Each seen element is searched in the another container with the method search(). So the container r must export the search() method, which frequently is the case for containers oriented to fast retrieval.

Warning
On some container, concretely DynList, the size is computed, not retrieved. So take in account this fact.
Parameters
[in]rcontainer on which the searches will be performed.
Returns
true if the container have the same size and all the elements of this are present in r

◆ exists() [1/2]

bool Aleph::FunctionalMethods< ArrayQueue< T > , T >::exists ( Operation &  op) const

This method has complexity $O(n)$ in average and worst case.

Parameters
[in]opoperation for testing existence
Returns
true if it exists an item for which op return true; false otherwise.
Exceptions
anythingthat could throw op

◆ exists() [2/2]

◆ expand()

template<typename T>
bool Aleph::MemArray< T >::expand ( const size_t  first = 0)
inlineprotectedinherited

Test is array is full and if affrimative, then expand the array twice as long and copy the content by swapping.

This method first allocates a chunck of 2*dim and then copies from first index the n contained entries to the new chunck.

Parameters
[in]firstindex where is found the first item of array
Returns
true if the array was full and then a new twice as long was allocated
Exceptions
bad_allocif there is no enough memory
+ Here is the caller graph for this function:

◆ filter() [1/2]

DynList<T> Aleph::FunctionalMethods< ArrayQueue< T > , T >::filter ( Operation &  operation) const
inlineinherited

Filter the elements of a container according to a matching criteria.

This method builds a dynamic list with copies of items of container matching a criteria defined by operation, which should have the following signature:

bool operation(const T & item)

If operation return true then item matches the criteria; otherwise, operation must return false.

For example, if the container has integer, the the following code snippet would return a list containing the items greater than 100:

c.filter([] (auto item) { return item > 100; });
Parameters
[in]operationdefining the flter criteria
Returns
a DynList<T> with the matched elements.
Exceptions
anythingthat could throw operation or bad_alloc if there is no enough memory

◆ find_index() [1/2]

size_t Aleph::LocateFunctions< ArrayQueue< T > , T >::find_index ( Operation &  operation) const
inlinenoexceptinherited

Find the position of an item in the container according to a searching criteria.

find_index(operation) traverses the container and on each item perform operation(item). If the result of operation is true, then the traversal is stopped and the position of the current item (which mathes operation) is returned.

operation must have the following signature:

bool operation(const typename Container::Item_Type & item)
Warning
Frequent use of this method will definitively degrade the performance. Try not to use this method inside loops. In general, if you falls in this situation, the consider your design and use a faster approach.
Parameters
[in]<tt>operation</tt>to be performed on each item for matching a searching criteria.
Returns
the last seen position. If the item is not found, then the number of items is returned.

inlinenoexceptinherited

Safe sequential searching of an item matching a criteria.

find_item(operation) traverses the container and on each item perform operation(item). If the result of operation is true, then the traversal is stopped and duple containg a copy of found item is returned.

The method is said safe because returns a copy of item.

operation must have the following signature:

bool operation(const typename Container::Item_Type & item)
Parameters
[in]<tt>operation</tt>to be used as searching criteria

◆ fold() [1/2]

T Aleph::FunctionalMethods< ArrayQueue< T > , T >::fold ( const T &  init,
Operation &  operation 
) const
inlinenoexceptinherited

Simplified version of foldl() where the folded type is the same type of elements stored in the container.

See also
foldl(const __T & init, Op & op)

◆ fold() [2/2]

T Aleph::FunctionalMethods< ArrayQueue< T > , T >::fold ( const T &  init,
Operation &&  operation 
) const
inlinenoexceptinherited

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ foldl() [1/2]

__T Aleph::FunctionalMethods< ArrayQueue< T > , T >::foldl ( const __T &  init,
Op &  op 
) const
inlinenoexceptinherited

Fold the elements of the container to a specific result.

foldl(init, op) set an internal variable acc of type __T to init value. Then it traverses the container and on each item it performs:

acc = op(acc, op(acc, item);

So acc serves as a sort of accumulator.

op should have the following signature:

__T op(__T acc, const T & item);

Since foldl is overloaded with several operation structures, there is a certain flexibility with the parameter qualifiers. You could, for example, to declare acc and/or item by value.

The method is a template. The first template parameter __T specifies the final folded type. By default, this type is T (the type of elements stored in the container). The second parameter is the operation. If the folded type is the same than T (the type of item stored), the you can simply write a foldl(). For example, if the container stores integer, in order to determine the maximum of all elements you could do:

c.foldl(std::numeric_limits<int>::min(), [] (int acc, int item)
  {
    return std::min(acc, item);
  });

When the folded type is different than T, then you must specify the folded type as template parameter. For example, if you want to compute the sum of inversed elements, the you could do it as follows:

c.template foldl<double>(0, [] (double acc, int item)
  {
    return acu + 1.0/item;
  });
Parameters
[in]initinitial value of folded value (or accumulator).
[in]opoperation to be performed on each item and used for folding.
Returns
the final folded computation.
Exceptions
anythingthat could throw op

◆ length()

size_t Aleph::FunctionalMethods< ArrayQueue< T > , T >::length ( ) const
inlinenoexceptinherited

Count the number of elements of a container.

This method counts the number of elements stored in the container.

Note
Take in account that this method computes; it does not retrieve. Consequently it always takes $O(n)$. However, for many containers this number is already stored and retrievable in $O(1)$ through the methos size()
Returns
the number of elements stored in the container.

◆ maps() [1/2]

DynList<__T> Aleph::FunctionalMethods< ArrayQueue< T > , T >::maps ( Operation &  op) const
inlineinherited

Map the elements of the container.

maps(op) produces a dynamic list resulting of mapping of each element of container item to the result of operation op(item).

maps() is a template method which receives as template parameters the type __T, which is the type of target or range of mapping, and the transforming operation. By default __T is the same type of the elements stored in the container.

operation should have the following signature:

__T operation(const T & item)

So, operation(item) performs a transformation of item towards the type __T.

If __T ==T`, which is common and by default, then you could specify a mapping without need of template specification. For example, if the container has integer values, the a mapping of item multiplied by 4 could be very simply written as follows:

c.maps([] (int item) { return 4*i; });

In contrast, if the range type is different than the domain type, then it is necessary to specify the template keyword in the method call. For example, if the range is double and you want to return the elements divided by 4, the could do as follows:

c.template maps<double>([] (int item) { return 1.0*item/4; });
Parameters
[in]opoperation to be performed in order to do the transformation on an item
Returns
a `DynList<__T> object containing the mapped items. The order of resulting list is the same than the order of visit of the iterator for the container.
Exceptions
anythingthat could throw op or bad_alloc if there is no enough memory

DynList<__T> Aleph::FunctionalMethods< ArrayQueue< T > , T >::maps_if ( Prop  prop,
Operation &  op 
) const

maps_if(prop, op) traverses each item of container, on each item it tests the proposition prop. If this last is true, then the item is mapped through the function op(item).

Parameters
[in]opoperation to be perfomed in order to do the transformation on an item.
[in]propa lambda returning a bool which perform the logical test.
Returns
a `DynList<__T> object containing the mapped items. The order of resulting list is the same than the order of visit of the iterator for the container.

◆ nth() [1/2]

T & Aleph::LocateFunctions< ArrayQueue< T > , T >::nth ( const size_t  n)
inlineinherited

Return the n-th item of container.

The notion of ordinal depends of type of container. On list, probably will be the insertion order. On binary search trees will be the nth smaller item. On hash tables will be pseudo random.

Warning
Frequent use of this method will definitively degrade the performance. Try not to use this method inside loops. In general, if you falls in this situation, then consider your design and to use an faster approach.
Parameters
[in]nthe nth item to find

inlineinherited

Filter the elements of a container according to a matching criteria and determine its positions respect to the traversal of container.

pfilter(operation) is very similar to filter(), but instead of building a list of filtered elements, it builds a list of pairs with form (item, pos), where item is a copy of filtered element and pos is its position respect to the traversal order. The position is relative to the container type.

The pair is defined with a tuple:

std::tuple<T, size_t>
