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.

lock()

void xAODPrivate::THolderBucket::lock ( )

inlineoverridevirtual

Lock the held object. A no-op.

Implements DataBucketBase.

object()

void* xAODPrivate::THolderBucket::object ( )

inlineoverridevirtual

Return the object held.

Implements DataBucketBase.

void xAODPrivate::THolderBucket::relinquish ( )

inlineoverridevirtual

Give up ownership of the bucket's contents. A no-op.

tinfo()

const std::type_info& xAODPrivate::THolderBucket::tinfo ( ) const

inlineoverridevirtual

Return the type_info of the stored object.
