Detailed Description

Class to handle with lists of Data pointers.

Member Typedef Documentation

pPtrVector

typedef PtrVector* pPtrVector

Constructor & Destructor Documentation

PtrVector() [1/2]

PtrVector

(

)

Default constructor.

PtrVector() [2/2]

PtrVector

(

const PtrVector &

src

)

Copy constructor.

Stored object copied from src will NOT be deleted upon clear or object deletion even if subsequently added with push commands

~PtrVector()

virtual ~PtrVector ( )

virtual

Virtual destructor.

This method will delete the stored object too, unless it was create with copy constructor PtrVector(const PtrVector& src) or assigned from other object operator=(const PtrVector& src)

Member Function Documentation

at() [1/2]

Data * at

(

size_t

n

)

Returns a reference to the element at position n in the vector container.

Parameters

n	Position of an element in the container.

Returns

The element at the specified position in the vector.

at() [2/2]

const Data * at

(

size_t

n

)

const

Returns a reference to the element at position n in the vector container.

Parameters

n	Position of an element in the container.

Returns

The element at the specified position in the vector.

back()

Data * back

(

)

const

Get a reference to the last element in the container.

Returns

A reference to the last element in the container.

clear()

void clear

(

)

Erases all elements from the container. After this call, size() returns zero.

This method will delete the stored object too, unless it was create with copy constructor PtrVector(const PtrVector& src) or assigned from other object operator=(const PtrVector& src)

front()

Data * front

(

)

const

Get a reference to the first element in the container.

Returns

a reference to the first element in the container.

operator=()

PtrVector & operator=

(

const PtrVector &

src

)

Assigment operator overload.

Parameters

src	The source object

Returns

A reference to this object

Stored object copied from src will NOT be deleted upon clear or object deletion even if subsequently added with push commands

operator[]() [1/2]

Data * operator[]

(

size_t

n

)

Returns a reference to the element at position n in the vector container.

Parameters

n	Position of an element in the container.

Returns

The element at the specified position in the vector.

operator[]() [2/2]

const Data * operator[]

(

size_t

n

)

const

Returns a reference to the element at position n in the vector container.

Parameters

n	Position of an element in the container.

Returns

The element at the specified position in the vector.

popBack()

void popBack

(

)

Removes the last element of the container.

pushBack()

void pushBack

(

const pData &

value

)

Appends the given element value to the end of the container.

Parameters

value

The value of the element to append

Stored object value will be deleted upon clear or object deletion unless this container was create with copy constructor PtrVector(const PtrVector& src) or assigned from other object operator=(const PtrVector& src)

resize() [1/2]

void resize

(

size_t

count

)

Resizes the container to contain count elements. The new element will be initialized with default values.

Parameters

count

The new size of the container

resize() [2/2]

void resize	(	size_t	count,
		const pData &	value )

Resizes the container to contain count elements.

Parameters

count	The new size of the container
value	The value to initialize the new elements with

size()

size_t size

(

)

const

Get the number of elements in the container.

Returns

The number of elements in the container
