Description

This session provides methods for searching among DeviceEnabler objects. The search query is constructed using the DeviceEnablerQuery.

This session defines views that offer differing behaviors for searching.

  • isolated system view: searches are restricted to device enablers in this system

Device constrainer enablers may have a query record indicated by their respective record types. The query record is accessed via the DeviceEnablerQuery.
