  8. def reduceEqualKmers(table: KmerTable, into: Int, from: Int): Unit

    Apply a binary operation op(into, from) on the tags of the k-mers at these positions, writing the result in the tags of "into", writing the zero value into the tags of "from".

    Apply a binary operation op(into, from) on the tags of the k-mers at these positions, writing the result in the tags of "into", writing the zero value into the tags of "from". This method will only be called on equal k-mers.

    table

    The table containing k-mers

    into

    Target k-mer index in the table (k-mer A in op(A,B))

    from

    Source k-mer index in the table (k-mer B in op(A,B))

  9. def shouldKeep(table: KmerTable, kmer: Int): Boolean

    Whether to keep the k-mer (together with tag data) after reduction.

    Whether to keep the k-mer (together with tag data) after reduction.

    table

    The table containing k-mers

    kmer

    Index of k-mer to be tested
