Detailed Description

template<class DV>
class SG::DVLConstDataVectorBucket< DV >

DataBucket class for ConstDataVector.

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

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

Constructor & Destructor Documentation

◆ DVLConstDataVectorBucket() [1/2]

template<class DV>

SG::DVLConstDataVectorBucket< DV >::DVLConstDataVectorBucket ( ConstDataVector< DV > * data )

Constructor from a payload object.

Parameters

data	Object to hold in the bucket.

◆ DVLConstDataVectorBucket() [2/2]

template<class DV>

SG::DVLConstDataVectorBucket< DV >::DVLConstDataVectorBucket ( std::unique_ptr< ConstDataVector< DV > > data )

Constructor from a payload object.

Parameters

data	Object to hold in the bucket.

Member Function Documentation

◆ cast() [1/4]

virtual void * DataBucketBase::cast	(	CLID	clid,
		const std::type_info &	tinfo,
		SG::IRegisterTransient *	irt = 0,
		bool	isConst = true )

virtualinherited

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. By default, this uses type_info.

Reimplemented in Athena::DataBucketBranch, BareDataBucket, SG::DataBucket< T >, SG::DVLDataBucket< T >, SG::DVLDataBucket< U >, SG::MetaContDataBucket< T >, SG::MetaContDataBucket< U >, SG::PyDataBucket, SG::SymlinkDataObject, and xAODPrivate::HolderBucket.

◆ cast() [2/4]

virtual void * DataBucketBase::cast	(	const std::type_info &	tinfo,
		SG::IRegisterTransient *	irt = 0,
		bool	isConst = true )

pure virtualinherited

Return the contents of the DataBucket, converted to type given by std::type_info.

Note that only derived->base conversions are allowed here.

Parameters

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.

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

◆ cast() [3/4]

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.

◆ cast() [4/4]

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 >.

◆ classID()

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()

◆ 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.

Definition DataBucket.h:130

◆ ptr()

inlineprotectedinherited

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()

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()

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.
