Detailed Description

template<typename Tbase, typename Tcomplex = Tbase>
class csVertexListWalker< Tbase, Tcomplex >

Helper class to make it easier to iterate over elements from renderbuffers, with automatic conversion to Tbase.

Elements can also be queried as Tcomplex, which must consist of multiple Tbase.

Remarks:

The element actually returned (converted or not) is stored in an array internal to the class. That has the consequence that for a queried element, you will only get what you expect as long as operator++() is not called. If you need to retain an element, you have to copy it! This also means you cannot really manipulate the buffer this way...

Constructor & Destructor Documentation

template<typename Tbase, typename Tcomplex = Tbase>

csVertexListWalker< Tbase, Tcomplex >::csVertexListWalker	(	iRenderBuffer *	buffer,
		size_t	desiredComponents = 0,
		const Tbase *	defaultComponents = 0
	)			[inline]

Construct new walker.

Parameters:

	buffer	The render buffer to walk over.
	desiredComponents	Number of components to fetch from the buffer. Those can differ from the real number; the components are filled up with default values, if necessary. If 0, the component count as set in the buffer will be returned.
	defaultComponents	The default values for components, if more are requested than available. If 0, the values {0,0,0,1} are used.
