Detailed Description

template<typename T, class Base>
class epics::pvData::detail::PVVectorStorage< T, Base >

Common code for PV*Array.

Member Function Documentation

replace()

template<typename T, class Base>

virtual void epics::pvData::detail::PVVectorStorage< T, Base >::replace ( const const_svector &  next )

pure virtual

Discard current contents and replaced with the provided. Fails for Immutable arrays calls postPut()

Implemented in epics::pvData::PVValueArray< PVUnionPtr >, epics::pvData::PVValueArray< PVStructurePtr >, and epics::pvData::PVValueArray< T >.

reuse()

template<typename T, class Base>

svector epics::pvData::detail::PVVectorStorage< T, Base >::reuse ( )

inline

Remove and return the current array data or an unique copy if shared.

Does not (and should not) call postPut()

The returned shared_vector<T> will have unique()==true.

Definition at line 1155 of file pvData.h.

swap()

template<typename T, class Base>

virtual void epics::pvData::detail::PVVectorStorage< T, Base >::swap ( const_svector &  other )

pure virtual

Exchange our contents for the provided.

Exceptions

std::logic_error

for Immutable arrays.

Callers must ensure that postPut() is called after the last swap() operation.

Before you call this directly, consider using the reuse(), or replace() methods.

Implemented in epics::pvData::PVValueArray< PVUnionPtr >, epics::pvData::PVValueArray< PVStructurePtr >, and epics::pvData::PVValueArray< T >.
