    • writer

      public static <A, G extends Gene<A, G>, C extends Chromosome<G>> Writer<Collection<Genotype<G>>> writer(Writer<? super C> writer)
      Create a writer for genotypes of arbitrary chromosomes. How to write the genotype chromosomes is defined by the given Writer. The following writer allows writing double-gene chromosomes: 
      final Writer<Collection<Genotype<DoubleGene>>> writer =
    Writers.Genotypes.writer(Writers.DoubleChromosome.writer());
      Type Parameters:
      A - the allele type
      G - the gene type
      C - the chromosome type
      Parameters:
      writer - the chromosome writer
      Returns:
      a new genotype writer
      Throws:
      NullPointerException - if the given chromosome writer is null

    • write

      public static <A, G extends Gene<A, G>, C extends Chromosome<G>> void write(OutputStream out, Collection<Genotype<G>> data, String indent, Writer<? super C> chromosomeWriter) throws XMLStreamException
      Write the given Genotype to the given output stream.
      Type Parameters:
      A - the allele type
      G - the gene type
      C - the chromosome type
      Parameters:
      out - the target output stream
      data - the genotypes to write
      indent - the XML level indentation
      chromosomeWriter - the chromosome writer used to write the genotypes
      Throws:
      XMLStreamException - if an error occurs while writing the chromosome
      NullPointerException - if the one of the arguments is null

    • write

      public static <A, G extends Gene<A, G>, C extends Chromosome<G>> void write(OutputStream out, Collection<Genotype<G>> data, Writer<? super C> chromosomeWriter) throws XMLStreamException
      Write the given Genotype to the given output stream.
      Type Parameters:
      A - the allele type
      G - the gene type
      C - the chromosome type
      Parameters:
      out - the target output stream
      data - the genotypes to write
      chromosomeWriter - the chromosome writer used to write the genotypes
      Throws:
      XMLStreamException - if an error occurs while writing the chromosome
      NullPointerException - if the one of the arguments is null
