Detailed Description

Block of elements.

Colin Bernet

Date

January 2006

A PFBlock is:

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

addElement()

void PFBlock::addElement

(

reco::PFBlockElement *

element

)

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

associatedElements()

		std::multimap< double, unsigned > &	sortedAssociates,
		reco::PFBlockElement::Type	type = PFBlockElement::NONE,
		LinkTest	test = LINKTEST_RECHIT
	)		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..

Definition at line 60 of file PFBlock.cc.
