Examples of org.apache.vinci.transport.VinciFrame

org.apache.vinci.transport.VinciFrame
This is the "default" document class for use with the Vinci client and servable classes. VinciFrame implements a queryable frame from (nested) ArrayList data structures. Search time for a named tag is O(n) in the number of keys at a given depth, which is fine for all but the largest documents. VinciFrame complements the QueryableFrame adders and getters with several setter methods [fset(String, *)] for modifying the values of designated tags.
