Detailed Description

Helper for symLink_impl.

A simple DataBucket that holds an arbitrary pointer/clid. We stub out everything else that we don't use.

Member Function Documentation

cast() [1/4]

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

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.
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 from DataBucketBase.

cast() [2/4]

virtual void * SG::SymlinkDataObject::cast ( CLID clid, SG::IRegisterTransient * irt, bool isConst )

inlineoverridevirtual

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.

Implements DataBucketBase.

{ std::abort(); }

cast() [3/4]

virtual void * SG::SymlinkDataObject::cast ( const std::type_info & tinfo, SG::IRegisterTransient * irt, bool isConst )

inlineoverridevirtual

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.

Implements DataBucketBase.

Definition at line 97 of file StoreGate/src/VarHandleBase.cxx.

{ std::abort(); }

cast() [4/4]

template<class T>

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

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.

clID()

inlineoverridevirtual

{ return m_clid; }

lock()

virtual void SG::SymlinkDataObject::lock ( )

inlineoverridevirtual

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

Implements DataBucketBase.

object()

virtual void * SG::SymlinkDataObject::object ( )

{ return m_obj; }

relinquish()

virtual void SG::SymlinkDataObject::relinquish ( )

inlineoverridevirtual

Give up ownership of the DataBucket contents.

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

Implements DataBucketBase.

Definition at line 98 of file StoreGate/src/VarHandleBase.cxx.

{ std::abort(); }

tinfo()

virtual const std::type_info & SG::SymlinkDataObject::tinfo ( ) const

inlineoverridevirtual

Return the type_info for the stored object.

Implements DataBucketBase.

{ return typeid(void); }
