## Detailed Description

### template<typename T>
class PIVector< T >

Dynamic array of any type.

This class used to store dynamic array of any type of data. In memory data stored linear. You can insert item in any place of remove some items from any place. For quick add elements this is stream operator <<.

## Constructor & Destructor Documentation

template<typename T>

PIVector< T >::PIVector | ( |  | ) |
| inline

Contructs an empty vector

## Member Function Documentation

template<typename T>

PIVector< T > & PIVector< T >::fill | ( | const T & | f = `T()` | ) |
| inline

Fill vector with elements "t" leave size is unchanged and return reference to vector.

Example:

PIVector<char> vec;
vec << '1' << '2' << '3' << '4' << '5';
vec.fill('0');
piForeachC (char i, vec)
cout << i << ", ";
// 0, 0, 0, 0, 0,
template<typename T>

void PIVector< T >::resize | ( | size_t | new_size,
|  | const T & | f = `T()`
| ) |  |
| inline

Resize vector to size "size".

Elements removed from end of vector if new size < old size, or added new elements = "new_type" if new size > old size.
Example:

PIVector<int> vec;
vec << 1 << 2;
vec.resize(4);
piForeachC (int & i, vec)
cout << i << ", ";
// 1, 2, 0, 0,
vec.resize(3);
piForeachC (int & i, vec)
cout << i << ", ";
// 1, 2, 0,

  size(), clear()

template<typename T>

PIVector< T > & PIVector< T >::remove | ( | size_t | index,
|  | size_t | count = `1`
| ) |  |
| inline

Remove one element by index "index" and return reference to vector.

Remove "count" elements by first index "index" and return reference to vector.

Example:

PIVector<char> vec;
vec << '1' << '2' << '3' << '4' << '5';
vec.remove(1);
piForeachC (char i, vec)
cout << i << ", ";
// 1, 3, 4, 5,

  removeOne(), removeAll()

Example:

PIVector<char> vec;
vec << '1' << '2' << '3' << '4' << '5';
vec.remove(2, 2);
piForeachC (char i, vec)
cout << i << ", ";
// 1, 2, 5,

  removeOne(), removeAll()

template<typename T>

PIVector< T > & PIVector< T >::sort | ( | CompareFunc | compare = `compare_func` | ) |
| inline

Sort vector using quick sort algorithm and standard compare function.

Example:

PIVector<int> vec;
vec << 3 << 2 << 5 << 1 << 4;
vec.sort();
piForeachC (int & i, vec)
cout << i << ", ";
// 1, 2, 3, 4, 5,

With custom compare function:

static int mycomp(const int * v0, const int * v1) {
if (*v0 == *v1) return 0;
return *v0 < *v1 ? 1 : -1;
}
PIVector<int> vec;
vec << 3 << 2 << 5 << 1 << 4;
vec.sort(mycomp);
piForeachC (int & i, vec)
cout << i << ", ";
// 5, 4, 3, 2, 1,
template<typename T>

PIVector< T > & PIVector< T >::removeOne | ( | const T & | v | ) |
| inline

Remove no more than one element equal "v" and return reference to vector.

Example:

PIVector<char> vec;
vec << '1' << '2' << '3' << '2' << '1';
vec.removeOne('2');
piForeachC (char i, vec)
cout << i << ", ";
// 1, 3, 2, 1,

See also
  remove(), removeAll()

template<typename T>

PIVector< T > & PIVector< T >::removeAll | ( | const T & | v | ) |
| inline

Remove all elements equal "v" and return reference to vector.

Example:

PIVector<char> vec;
vec << '1' << '2' << '3' << '2' << '1';
vec.removeAll('2');
piForeachC (char i, vec)
cout << i << ", ";
// 1, 3, 1,
