Interface Tango::GroupAttribute

interface GroupAttribute

Local interface for grouped Attribute requests (locality constrained). GroupAttribute is a local client interface for reading and writing groups of attributes which belong to more than one Device. The reading and writing of the attributes is done via methods. GroupAttribute optimises the request so that it is executed in the shortest possible time. GroupAttribute is a local interface which exists only in the client i.e. it is not a network addressable object.
