Detailed Description

template<class Iterator>
class ElementProxy< Iterator >

A proxy for Iterators, such that an Iterator's element looks like an Iterator's element (!), even though it isn't (the internal storage layout may be different).

Parameters:

	Iterator	The Iterator must export
	array_t	(typedef) the type of each component
	Components	(enum) the number of components
	getComponent(int	idx,int c) a function returning a reference to the c'th component of the idx'th index in the field.

Parameters:

Owner

the Iterator referring to the array

const [inline]

Implicit type conversion into an array element.

Note:

This function creates a temporary object; it is convenient, but slow.
