Member Function Documentation

void FWSecVertexProxyBuilder::build	(	const reco::SecondaryVertexTagInfo &	iData,
		unsigned int	iIndex,
		TEveElement &	oItemHolder,
		const FWViewContext *
	)		[private, virtual]

iIndex is the index where iData is found in the container from which it came iItemHolder is the object to which you add your own objects which inherit from TEveElement

Reimplemented from FWSimpleProxyBuilderTemplate< reco::SecondaryVertexTagInfo >.
