EPICS pvDatabaseCPP

Release 4.6.0 - March 2021


pvDatabase is a framework for implementing a network accessible database of smart memory resident records. Network access is via pvAccess. The data in each record is a top level PVStructure as defined by pvData. The framework includes a complete implementation of ChannelProvider as defined by pvAccess. The framework can be extended in order to create record instances that implements services. The minimum that an extension must provide is a top level PVStructure and a process method.
