virtual void DataProxy< RecordT, DataT >::invalidateCache

(

)

[inline, protected, virtual]

indicates that the Proxy should invalidate any cached information as that information has 'expired' (i.e. we have moved to a new IOV)

Implements edm::eventsetup::DataProxy.

Definition at line 35 of file DataProxy.h.

                                 {
    // don't, preserve data for future access
    // m_data->invalidateCache();
  }

template<class RecordT , class DataT >

virtual void DataProxy< RecordT, DataT >::invalidateTransientCache

(

)

[inline, protected, virtual]

indicates that the Proxy should invalidate any cached information as that information was accessed transiently and therefore is not intended to be kept over the entire IOV. Default is to call invalidateCache().

Reimplemented from edm::eventsetup::DataProxy.
