EPICS 7 release 4.7.1

API changes to PvaClientMonitor

The create method that had arguments for stateChangeRequester and monitorRequester no longer exists.

API changes to PvaClientGet, ..., PvaClientMonitor

pvaClientGet, ..., pvaClientMonitor all implemented PvaClientChannelStateChangeRequester. This was never called and has been removed.

Works with pvDataCPP-7.0 and pvAccessCPP-6.0 versions

Will not work with older versions of these modules.

destroy methods removed

All the destroy methods are removed since implementation is RAII compliant.

API changes to PvaClientMonitor

The second argument of method

static PvaClientMonitorPtr create(
    PvaClientPtr const &pvaClient,
    epics::pvAccess::Channel::shared_pointer const & channel,
    epics::pvData::PVStructurePtr const &pvRequest
);

Is now changed to

static PvaClientMonitorPtr create(
    PvaClientPtr const &pvaClient,
    PvaClientChannelPtr const & pvaClientChannel,
    epics::pvData::PVStructurePtr const &pvRequest
);

A new method is also implemented

static PvaClientMonitorPtr create(
    PvaClientPtr const &pvaClient,
    std::string const & channelName,
    std::string const & providerName,
    std::string const & request,
    PvaClientChannelStateChangeRequesterPtr const & stateChangeRequester,
    PvaClientMonitorRequesterPtr const & monitorRequester
);

• In PvaClientMultiChannel checkConnected() now throws an exception if connect fails.
