ResizeArray Class Template Reference

A template class which implements a dynamically-growing, automatically resizing array of data of a given type. Elements in the array may be accessed via the [] operator. When new data is added to the end of an array, the size of the array is automatically increased if necessary. XXX Do not parametrize this class with a datatype which cannot be shallow-copied! This class uses memcpy to resize, and therefore classes which contain dynamically-allocated memory blocks will crash and burn if the ResizeArray ever gets resized. More...

Public Methods
	ResizeArray (int s=3)
	Constructor The first argument is the initial internal size of the array, i.e. the initial number of elements for which to allocate memory (although the initial external size of the array will be zero). More...
	~ResizeArray ()
int	num (void) const
	current size of array. More...
T &	operator[] (int N)
	unchecked accessor, for speed. More...
T const &	operator[] (int N) const
	a const version of above. More...
void	append (const T &val)
	add a new element to the end of the array. Return index of new item. More...
void	remove (int n)
	remove an item from the array, shifting remaining items down by 1. More...
void	clear ()
	delete entire array by defining size to be empty. More...
void	truncatelastn (int N)
	truncate the array by defining the size to be N items less. More...
int	find (const T &val)
	scan the array until the first item that matches in the array is found. Return the index if found, (-1) otherwise. More...

Detailed Description

template<class T>
class ResizeArray< T >

A template class which implements a dynamically-growing, automatically resizing array of data of a given type. Elements in the array may be accessed via the [] operator. When new data is added to the end of an array, the size of the array is automatically increased if necessary. XXX Do not parametrize this class with a datatype which cannot be shallow-copied! This class uses memcpy to resize, and therefore classes which contain dynamically-allocated memory blocks will crash and burn if the ResizeArray ever gets resized.
