Class TwoBitSequenceReader.TwoBitArrayWorker<C extends NucleotideCompound>

java.lang.Object

org.biojava.nbio.core.sequence.storage.BitSequenceReader.BitArrayWorker<C>

org.biojava.nbio.core.sequence.storage.TwoBitSequenceReader.TwoBitArrayWorker<C>

Type Parameters:

C - Must extend NucleotideCompound

Enclosing class:

TwoBitSequenceReader<C extends NucleotideCompound>

public static class TwoBitSequenceReader.TwoBitArrayWorker<C extends NucleotideCompound>
extends BitSequenceReader.BitArrayWorker<C>

Extension of the BitArrayWorker which provides the 2bit implementation code. This is intended to work with the 4 basic nucelotide types. If you require a different version of the encoding used here then extend and override as required.
