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() [1/8]

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 xAODPrivate::THolderBucket, SG::DVLDataBucket< T >, SG::DVLDataBucket< DV >, SG::DataBucket< T >, SG::DataBucket< DV >, and SG::MetaContDataBucket< T >.

cast() [2/8]

virtual void* DataBucketBase::cast

Return the contents of the DataBucket, converted to type given by clid.

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.

cast() [3/8]

virtual void* DataBucketBase::cast

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.

cast() [5/8]

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.

cast() [6/8]

virtual void* DataBucketBase::cast

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.

cast() [7/8]

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() [8/8]

template<class T >

T* DataBucketBase::cast

(

class T

)

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.

lock()

virtual void SG::SymlinkDataObject::lock ( )

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.
