Method Detail

encodeRefinementValuePath

public static String encodeRefinementValuePath(List<String> values)

Encodes a value path as a string for the purposes of a refinement request

decodeRefinementValuePath

public static List<String> decodeRefinementValuePath(String valuePath)

Decodes a value path string specified for refinement.

PivotListEntry.COUNT

getPivots

public static List<NamedList<Object>> getPivots(NamedList<Object> pivotList)

mergeStats

public static Map<String,StatsValues> mergeStats(Map<String,StatsValues> merged,
                                                 NamedList<NamedList<NamedList<?>>> remoteWrapper,
                                                 org.apache.solr.handler.component.StatsInfo statsInfo)

Given a mapping of keys to StatsValues representing the currently known "merged" stats (which may be null if none exist yet), and a NamedList containing the "stats" response block returned by an individual shard, this method accumulates the stats for each StatsField found in the shard response with the existing mergeStats

Returns:

the original merged Map after modifying, or a new Map if the merged param was originally null.
