Colin Bernet

Date

January 2006

A PFBlock is:

• a set of topologically connected elements.
• a set of links between these elements

	)		const

lock an element ( unlink it from the others ) Colin: this function is misleading void lock(unsigned i, LinkData& linkData ) const; fills a map with the elements associated to element i. elements are sorted by increasing distance. if specified, only the elements of type "type" will be considered if specified, only the link calculated from a certain "test" will be considered: distance test, etc..
