Author:: Colin Bernet

Date:: January 2006

a set of links between these elements

void PFBlock::addElement ( reco::PFBlockElement * element )

add an element to the current PFBlock the block will keep a copy.

	)		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..
