Detailed Description

template<class RecordT, class DataT, typename Initializer = cond::DefaultInitializer<DataT>>
class DataProxy< RecordT, DataT, Initializer >

Description: Base class for data Proxies held by a EventSetupRecord

Usage: This class defines the interface used to handle retrieving data from an EventSetup Record.

template<class RecordT , class DataT , typename Initializer = cond::DefaultInitializer<DataT>>

virtual void DataProxy< RecordT, DataT, Initializer >::invalidateCache ( )

inlineprotectedvirtual

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 42 of file DataProxy.h.

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

template<class RecordT , class DataT , typename Initializer = cond::DefaultInitializer<DataT>>

virtual void DataProxy< RecordT, DataT, Initializer >::invalidateTransientCache ( )

inlineprotectedvirtual

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.
