Class RandomCodec

Lucene.Net.Codecs.Codec that assigns per-field random Lucene.Net.Codecs.PostingsFormats.

The same field/format assignment will happen regardless of order, a hash is computed up front that determines the mapping. This means fields can be put into things like HashSet<T>s and added to documents in different orders and the test will still be deterministic and reproducable.

Constructors

RandomCodec(Random)

Lucene.Net.Codecs.Codec that assigns per-field random Lucene.Net.Codecs.PostingsFormats.

The same field/format assignment will happen regardless of order, a hash is computed up front that determines the mapping. This means fields can be put into things like HashSet<T>s and added to documents in different orders and the test will still be deterministic and reproducable.

Declaration

public RandomCodec(Random random)

Parameters

Type	Name	Description
Random	random

RandomCodec(Random, ISet<string>)
