Golang WriteIndex Examples

Example #1

File: index.go Project: pombredanne/hts

// WriteIndex writes the Index to the given io.Writer.
func WriteIndex(w io.Writer, idx *Index) error {
	err := binary.Write(w, binary.LittleEndian, baiMagic)
	if err != nil {
		return err
	}

	err = binary.Write(w, binary.LittleEndian, int32(len(idx.idx.Refs)))
	if err != nil {
		return err
	}
	return internal.WriteIndex(w, &idx.idx, "bam")
}

Example #2

File: tabix.go Project: pombredanne/hts

// WriteTo writes the index to the given io.Writer. Note that
// the tabix specification states that the index is stored as BGZF, but
// WriteTo does not perform compression.
func WriteTo(w io.Writer, idx *Index) error {
	err := binary.Write(w, binary.LittleEndian, tbiMagic)
	if err != nil {
		return err
	}

	err = binary.Write(w, binary.LittleEndian, int32(len(idx.idx.Refs)))
	if err != nil {
		return err
	}
	err = writeTabixHeader(w, idx)
	if err != nil {
		return err
	}

	return internal.WriteIndex(w, &idx.idx, "tabix")
}
