Array optimized for dynamically changing its size.

Constructor & Destructor Documentation

template<class T, class Alloc = std::allocator<T>>

glv::Buffer< T, Alloc >::Buffer

(

int

capacity = 0

)

[inline, explicit]

Parameters:

[in]

capacity

capacity of buffer

Member Function Documentation

template<class T, class Alloc = std::allocator<T>>

void glv::Buffer< T, Alloc >::assign	(	int	n,
		const T &	v
	)			[inline]

Assign value to elements.

This function fills a Buffer with n copies of the given value. Note that the assignment completely changes the buffer and that the resulting size is the same as the number of elements assigned. Old data may be lost.

template<class T, class Alloc = std::allocator<T>>

void glv::Buffer< T, Alloc >::resize

(

int

n

)

[inline]

Resize buffer.

This will set both the size and capacity of the buffer to the requested size. If the number is smaller than the current size the buffer is truncated, otherwise the buffer is extended and new elements are default-constructed.

template<class T, class Alloc = std::allocator<T>>

void glv::Buffer< T, Alloc >::size

(

int

n

)

[inline]

Set size of buffer avoiding memory reallocation when possible.

If the requested size is larger than the current capacity, then the buffer will be resized.
