Detailed Description

template<typename C>
class edm::MultiAssociation< C >::LazyFiller

LazyFiller for the MultiAssociation. It is slower than FastFiller, as it keeps a copy of the input before filling it (unless you use swapValues) Anyway it has no constraints on the order of the keys, or the number of fillers It can also be copied around by value without cloning its keys (e.g to put it into a std::vector) If you set fillOnExit to 'true', it will fill the MultiAssociation automatically when going out of scope

Member Function Documentation

template<typename C >

void edm::MultiAssociation< C >::LazyFiller::fill ( void )

Does the real filling. Until this is called, the map is not modified at all. Calling this twice won't have any effect (but you can't modify a LazyFiller after calling 'fill()') Implementation note: inside, it just makes a FastFiller and uses it.

void edm::MultiAssociation< C >::LazyFiller::setFillOnExit ( bool fillOnExit ) [inline]

If set to true, the LazyFiller wil call 'fill()' when it goes out of scope.

void edm::MultiAssociation< C >::LazyFiller::setValues	(	const KeyRef &	k,

Sets the Collection values associated to this key, making copies of those in refs.

void edm::MultiAssociation< C >::LazyFiller::swapValues	(	const KeyRef &	k,
		Collection &	refs
	)

Swaps the Collection values associated to this key with the ones in 'ref' This is expected to be faster than 'setValues'.
