template <class value_type> struct fill

Stores a counted number of duplicate elements.

Member Types

• typedef value_type type so that generic wrappers can access this containers value_type
• typedef const_iterator iterator so that algorithms dependent upon iterator work.
• fill::const_iterator

Member Variables

• value_type value represents the value of all of the elements stored.
• int count represents the number of elements this container stores.

Member Functions

Constructor

Constructs a fill, initializing its contents depending on the constructor version used. There is no default constructor.

fill(int count, value_type value)

sets count and value directly.

fill(const_iterator left, const_iterator right)

where left and right demarcate the bounds of another fill container. This sets count to right-left and value to the value pointed to by left.

Utility

Basic functions necessary for algorithm execution.

int size()

returns the value of count.

Iterators

const_iterator begin()

returns an iterator to the first element.

const_iterator end()

returns an iterator to one after the last element.

const_iterator rbegin()

returns an iterator to the last element.

const_iterator rend()

returns an iterator to one before the first element.

const_iterator at(int i)

returns an iterator to the ith element.

Accessors

value_type front()

returns value.

value_type back()

returns value.

value_type get(int i)

returns value.

value_type operator[](int i)

returns value.

Slicing

slice<fill<value_type> > deref()

wraps this fill with a slice. This is particularly useful if an algorithm gives you a container filled with iterators. You can convert it into a slice with a single call to this function.

slice<range<iterator> > sub(int start, int end)

returns a slice of this container of the elements within the range [start,end).

slice<range<iterator> > sub(int start)

returns a slice of this container of the elements after start.

slice<range<iterator> > sub()

returns a slice of all the elements in this container.

static slice<range<const_iterator> > sub(const_iterator start, const_iterator end)

returns a slice of all the elements within the range [start,end) of a fill container.

fill<value_type> subcpy(int start, int end)

see above. This returns a copy instead of a slice.

fill<value_type> subcpy(int start)

see above. This returns a copy instead of a slice.

fill<value_type> subcpy()

see above. This returns a copy instead of a slice.

fill<typename container::iterator> sample(container &c)

uses the values of the fill container as indices into c. Returns another fill container with the indexed value from c.

• fill<int> idx() This is the inverse of sample().

Modifiers

void swap(fill<value_type> &root)

swaps the contents of this fill container with another.

fill<value_type> &operator=(const fill<value_type> &root)

sets the contents of this fill container equal the contents of another.

Non-Member Functions

Comparison

Compares two fill containers by comparing value followed by count.

• bool operator==(fill<value_type1> s1, fill<value_type2> s2)
• bool operator!=(fill<value_type1> s1, fill<value_type2> s2)
• bool operator<(fill<value_type1> s1, fill<value_type2> s2)
• bool operator>(fill<value_type1> s1, fill<value_type2> s2)
• bool operator<=(fill<value_type1> s1, fill<value_type2> s2)
• bool operator>=(fill<value_type1> s1, fill<value_type2> s2)

Compares a fill container to a generic slice by calling compare().

• bool operator==(fill<value_type1> s1, core::slice<container2> s2)
• bool operator!=(fill<value_type1> s1, core::slice<container2> s2)
• bool operator<(fill<value_type1> s1, core::slice<container2> s2)
• bool operator>(fill<value_type1> s1, core::slice<container2> s2)
• bool operator<=(fill<value_type1> s1, core::slice<container2> s2)
• bool operator>=(fill<value_type1> s1, core::slice<container2> s2)
• bool operator==(core::slice<container1> s1, fill<value_type2> s2)
• bool operator!=(core::slice<container1> s1, fill<value_type2> s2)
• bool operator<(core::slice<container1> s1, fill<value_type2> s2)
• bool operator>(core::slice<container1> s1, fill<value_type2> s2)
• bool operator<=(core::slice<container1> s1, fill<value_type2> s2)
• bool operator>=(core::slice<container1> s1, fill<value_type2> s2)

Examples

#include <std/ascii_stream.h>
#include <std/fill.h>

using namespace core;

int main()
{
    fill<int> f(0, 10);
    cout << f << endl;
    return 0;
