From source file org.seqdoop.hadoop_bam.VCFRecordReader.java

/** The key is the bitwise OR of the chromosome index in the upper 32 bits
 * and the 0-based leftmost coordinate in the lower.
 *
 * The chromosome index is based on the ordering of the contig lines in the VCF
 * header. If a chromosome name that cannot be found in the contig lines is
 * used, that name is instead hashed to form the upper part of the key.

From source file org.shaf.core.io.hadoop.WholeFileRecordReader.java

/**
 * The {@code RecordReader} for the whole files. The file name becomes a record
 * key and the file body becomes a record value.

From source file org.utils.TarballReader.java

/**
 * TarballReader.
 *
 * Outputs for file included in a tarball a key/value pair where the key is
 * the file name appended with date and time (.DYYMMDD.THHMMSS) and the value
