Java bean used to encapsulate the results of a provenance query.
This takes the form of a nested map, see getAnswer() for details on its structure.

Method Detail

getAnswer

public java.util.Map<QueryVar,java.util.Map<java.lang.String,java.util.List<Dependencies>>> getAnswer()

Returns:

a Map of the form: QueryVar --> ( <path> --> [ Dependencies ]) where

• QueryVar denotes one of the ports in the <select> element of the input query, for example: converter:atlasSlice
• <path> is the index within the value associated to the port, for instance [1,2,3] or []. The inner Map structure accounts for multiple paths, so for example if the query asked for the provenance of elements [1,2] and [2,3] of the value bound to converter:atlasSlice, then the inner Map structure contains two entries, one for each of the two paths.
• for each such path, the corresponding [Dependencies] is a list of Dependencies, each associated with one target processor and port mentioned in the input query. For example, for path [1,2] of value bound to converter:atlasSlice, you may see the following list of Dependencies:
  • converter:atlasSlice:[2]
  • slicer:atlasAverage[2]
  • slicer:atlasAverage[0]
  etc.
  Each of these elements is described by a Java bean, LineageQueryResultRecord, which represents a single provenance data record. This means that the particular value depends on each of these other values that are mentioned in the Dependencies list.
