Detailed Description

Hold the persistent representation for a ViewVector.

Base class for ViewVector; not to be used directly.

Definition at line 37 of file ViewVectorBase.h.

Constructor & Destructor Documentation

~ViewVectorBase()

virtual SG::ViewVectorBase::~ViewVectorBase ( )

virtualdefault

Destructor.

Member Function Documentation

clearPersistent()

void SG::ViewVectorBase::clearPersistent

(

)

Clear the persistent data.

doToPersistent()

template<class DV >

void SG::ViewVectorBase::doToPersistent ( DV &  v )

protected

Convert to persistent form.

Parameters

v	The vector to convert.

This will abort if called for a class with no CLID.

doToPersistent1() [1/2]

template<class DV >

void SG::ViewVectorBase::doToPersistent1 ( DV &  , const std::false_type &    )

protected

Convert to persistent form.

Parameters

v	The vector to convert.

Called for classes that do not have a CLID. This will simply abort.

doToPersistent1() [2/2]

template<class DV >

void SG::ViewVectorBase::doToPersistent1 ( DV &  v, const std::true_type &    )

protected

Convert to persistent form.

Parameters

v	The vector to convert.

Called for classes that have a CLID.

doToTransient()

template<class DV >

void SG::ViewVectorBase::doToTransient ( DV &  v )

inlineprotected

Convert to persistent form.

Parameters

v	The vector to convert.

Dispatch based on whether the class has a CLID.

Definition at line 157 of file ViewVectorBase.h.

  {
#ifdef XAOD_STANDALONE
    doToTransient1 (v, std::true_type());
#else
    doToTransient1 (v, typename ClassID_traits<DV>::has_classID_tag());
#endif
  }

doToTransient1() [1/2]

template<class DV >

void SG::ViewVectorBase::doToTransient1 ( DV &  , const std::false_type &    )

inlineprotected

Convert to transient form.

Parameters

v	The vector to fill in.

Called for the case that DV doesn't have a CLID. A no-op.

This is also what will get called for the case of an older version of a schema-evolved vector.

Definition at line 147 of file ViewVectorBase.h.

{}

doToTransient1() [2/2]

template<class DV >

void SG::ViewVectorBase::doToTransient1 ( DV &  v, const std::true_type &    )

inlineprotected

Convert to persistent form.

Parameters

v	The vector to convert.

Class has a CLID; dispatch based on whether DV is a ConstDataVector.

Definition at line 131 of file ViewVectorBase.h.

  {
    doToTransient2 (v, std::is_same<DV, typename DV::base_data_vector>());
  }

doToTransient2() [1/2]

template<class DV >

void SG::ViewVectorBase::doToTransient2 ( DV &  , const std::false_type &    )

inlineprotected

Convert to transient form.

Parameters

v	The vector to fill in.

Called for the case that DV is not a ConstDataVector. A no-op.

Definition at line 121 of file ViewVectorBase.h.

{}

doToTransient2() [2/2]

template<class DV >

void SG::ViewVectorBase::doToTransient2 ( DV &  v, const std::true_type &    )

protected

Convert to transient form.

Parameters

v	The vector to fill in.

Called for classes that have a CLID if DV is not a ConstDataVector.

setClearOnPersistent()

void SG::ViewVectorBase::setClearOnPersistent

(

)

Set a flag to declare that the vector should be cleared on the next call to toPersistent().

This would be used in the case where we make a copy of the object being written.

toPersistent()

virtual void SG::ViewVectorBase::toPersistent ( )

pure virtual

Convert the vector to persistent form.

Implemented in ViewVector< DV >, and ViewVector< TestBContainer >.

toTransient()

virtual void SG::ViewVectorBase::toTransient ( )

pure virtual

Convert the vector to transient form.

Implemented in ViewVector< DV >, and ViewVector< TestBContainer >.
