Index<TText, IndexQGram<TShapeSpec[, TSpec]> > Include Headers seqan/index.h Parameters
TText | The text type. Types: String
TShapeSpec | The Shape specialization type. Note: This can be either a TSpec argument (e.g. SimpleShape) or a complete Shape class (e.g. Shape<Dna, SimpleShape>).
TSpec | The specializing type. Types: OpenAddressing Default: Default
Remarks The fibres (see Index and Fibre) of this index are a suffix array sorted by the first q characters (see QGramSA) and a q-gram directory (see QGramDir). Specialization of Index Specializations
OpenAddressing | An index based on an array of sorted q-grams.
