Detailed Description

template<class T>
class SG::DVLDataBucket< T >

A DataBucket specialized for DataVector/DataList.

DataVector and DataList have some special conversion requirements.

In particular, we may have a situation where we're asked to convert from DataVector<D> to DataVector<B>, where these two classes are not related by inheritance, but D derived from . (In practice, this arises when one has multiple inheritance, and can't mirror both arms with DataVector/DataList.)

This DataBucket allows such conversions to happen by making a copy of the container (as a view container) and converting the contained pointers. The new instance remains owned by the DataBucket.

Member Function Documentation

template<typename T >

void * SG::DVLDataBucket< T >::cast	(	const std::type_info &	tinfo,
		IRegisterTransient *	irt = 0,
		bool	isConst = true
	)			const [inline, virtual]

Return the contents of the DataBucket, converted to type given by std::type_info. Note that only derived->base conversions are allowed here.

Parameters:

	clid	The std::type_info of the type to which to convert.
	irt	To be called if we make a new instance.
	isConst	True if the object being converted is regarded as const.

template<typename T >

void * SG::DVLDataBucket< T >::cast	(	CLID	clid,
		IRegisterTransient *	irt = 0,
		bool	isConst = true
	)			const [inline, virtual]

Return the contents of the DataBucket, converted to type given by clid. Note that only derived->base conversions are allowed here.

Parameters:

	clid	The class ID to which to convert.
	irt	To be called if we make a new instance.
	isConst	True if the object being converted is regarded as const.
