# Vector< T > Class Template Reference
[Common interfaces]

## Detailed Description

### template<class T>
class Vector< T >

Ordered sequence of objects.

Each object has it's ordinal position.

## Public Member Functions
| Vector ()
| Default Constructor.
| Vector (int initsize, int incrementSize=0)
| Constructor with explicit vector size specification.
| ~Vector ()
| Default Destructor.
void | clear ()
| Clears vector.
int | size () const
| Returns number of elements, stored in vector.
void | setSize (int newSize)
| Changes vector size.
void | ensureCapacity (int minCapacity)
| Ensures, that vector can store specified number of elements without resizing.
void | addElement (const T el)
| Adds element into tail of sequence.
void | insertElementAt (const T el, int index)
| Inserts element at specified position and expand vector by one element.
void | setElementAt (const T el, int index)
| Replaces element at specified position with specified element.
void | removeElementAt (int index)
| Removes element at specified `index` and shift all elements.
bool | removeElement (const T el)
| Removes first found element el from vector.
int | indexOf (T el, int index) const
| Returns index of element, starting search from specified `index` parameter.
int | indexOf (T el) const
| Returns index of element, starting search from start of vector.
T | elementAt (int index) const
| Returns element at specified position.
T | lastElement () const
| Returns last element of vector.

## Constructor & Destructor Documentation

template<class T>
Vector< T >::Vector | ( | int | initsize,
|  | int | incrementSize = `0`
| ) |

  | Constructor with explicit vector size specification. Parameters:
  | initsize | Initial vector size.
  | incrementSize | Positive number, which should be added to vector size each time it reaches it maximum capacity. If zero, internal array, each time filled, is double sized.

## Member Function Documentation

template<class T>
void Vector< T >::setSize | ( | int | newSize | ) |

| Changes vector size. if `newSize` is more, than current size, vector is expanded with requested number of elements, and set these elements to null. If `newSize` is less, than current size, number of top elements is deleted from it.

template<class T>
void Vector< T >::setElementAt | ( | const T | el,
|  | int | index
| ) |

| Replaces element at specified position with specified element. Vector's size is not changed.

template<class T>
int Vector< T >::indexOf | ( | T | el,
|  | int | index
| ) | const

| Returns index of element, starting search from specified `index` parameter. Returns -1, if not found.

template<class T>
int Vector< T >::indexOf | ( | T | el | ) | const

| Returns index of element, starting search from start of vector. Returns -1, if not found.

template<class T>
T Vector< T >::elementAt | ( | int | index | ) | const

  | Returns element at specified position. Exceptions:
  | OutOfBoundException | If `index` is too big or less, than zero.

template<class T>
T Vector< T >::lastElement | ( |  | ) | const

  | Returns last element of vector. Exceptions:
  | OutOfBoundException | If vector has no elements.
