Class FastqReader

java.lang.Object

htsjdk.samtools.fastq.FastqReader

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, java.lang.Iterable<FastqRecord>, java.util.Iterator<FastqRecord>

public class FastqReader
extends java.lang.Object
implements java.util.Iterator<FastqRecord>, java.lang.Iterable<FastqRecord>, java.io.Closeable

Reads a FASTQ file with four lines per record. WARNING: Despite the fact that this class implements Iterable, calling iterator() method does not start iteration from the beginning of the file. Developers should probably not call iterator() directly. It is provided so that this class can be used in Java for-each loop.
