Detailed Description

template<class DV, class ALLOC>
class SG::DVLDataVectorWithAllocBucket< DV, ALLOC >

DataBucket class for DataVectorWithAlloc.

This is just the same as DVLDataBucket, except that we've got to convert the DataVectorWithAlloc to DataVector.

Note: Can be used to violate const-correctness. Don't use this yourself!

Member Function Documentation

◆ cast() [1/4]

virtual void* SG::DVLDataBucket< DV >::cast	(	CLID	clid,
		const std::type_info &	tinfo,
		SG::IRegisterTransient *	irt = `0`,
		bool	isConst = `true`
	)

overridevirtualinherited

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.
tinfo	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.

This allows the callee to choose whether to use clid or tinfo. Here we use clid.

Reimplemented from SG::DataBucket< DV >.

◆ cast() [2/4]

virtual void* SG::DVLDataBucket< DV >::cast	(	CLID	clid,
		IRegisterTransient *	irt = `0`,
		bool	isConst = `true`
	)

overridevirtualinherited

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.

Reimplemented from SG::DataBucket< DV >.

◆ cast() [3/4]

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

overridevirtualinherited

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.

Reimplemented from SG::DataBucket< DV >.

◆ cast() [4/4]

template<class T >

T* DataBucketBase::cast	(	SG::IRegisterTransient *	irt = `0`,
		bool	isConst = `true`
	)

inherited

Return the contents of the DataBucket, converted to type T.

Note that only derived->base conversions are allowed here. T must have a valid Class ID for this to work.

Parameters

irt	To be called if we make a new instance.
isConst	True if the object being converted is regarded as const.

◆ classID()

static const CLID& SG::DataBucket< DV >::classID ( )

staticinherited

◆ clID()

virtual const CLID& SG::DVLDataBucket< DV >::clID ( ) const

overridevirtualinherited

The CLID for the class of object we're holding.

May be different from that of the base DataVector in the case of a ViewVector.

Reimplemented from SG::DataBucket< DV >.

◆ cptr()

inlineprotectedinherited

Definition at line 131 of file DataBucket.h.

131 { return m_ptr; }

◆ lock()

virtual void SG::DataBucket< DV >::lock ( )

overridevirtualinherited

If the held object derives from ILockable, call lock() on it.

Implements DataBucketBase.

◆ object()

virtual void* SG::DataBucket< DV >::object ( )

inlineoverridevirtualinherited

Implements DataBucketBase.

◆ operator DV *()

SG::DataBucket< DV >::operator DV * ( )

71 { return ptr(); } //FIXME can we do without?

◆ ptr()

DV * SG::DataBucket< DV >::ptr ( )

inlineprotectedinherited

Definition at line 130 of file DataBucket.h.

130 { return m_ptr; }

◆ relinquish()

virtual void SG::DataBucket< DV >::relinquish ( )

inlineoverridevirtualinherited

Give up ownership of the DataBucket contents.

This leaks the contents and it is useful mainly for error handling.

Implements DataBucketBase.

Definition at line 121 of file DataBucket.h.

121 { m_ptr=0;} //LEAKS m_ptr

◆ tinfo() [1/2]

virtual const std::type_info& DataBucketBase::tinfo ( ) const

pure virtualinherited

Return the type_info for the stored object.

Implemented in SG::PyDataBucket, SG::DVLDataBucket< T >, SG::SymlinkDataObject, xAODPrivate::THolderBucket, xAODPrivate::HolderBucket, Athena::DataBucketBranch, SG::DataBucket< T >, and BareDataBucket.

◆ tinfo() [2/2]

virtual const std::type_info& SG::DVLDataBucket< DV >::tinfo ( ) const

overridevirtualinherited

The std::type_info for the class of object we're holding.

May be different from that of the base DataVector in the case of a ViewVector.

Reimplemented from SG::DataBucket< DV >.

◆ tryStaticConversion() [1/2]

void* SG::DataBucket< DV >::tryStaticConversion ( CLID clid )

protectedinherited

Try a conversion using static SG_BASES information.

Parameters

clid	The class ID to which to convert.

This can all be unfolded at compile time, so is fast, but doesn't take into account SG_ADD_BASES.

◆ tryStaticConversion() [2/2]

void* SG::DataBucket< DV >::tryStaticConversion ( const std::type_info & tinfo )

protectedinherited

Try a conversion using static SG_BASES information.

Parameters

tinfo The std::type_info of the type to which to convert.

This can all be unfolded at compile time, so is fast, but doesn't take into account SG_ADD_BASES.
