org.broadinstitute.gatk.engine.executive.WindowMaker
Transforms an iterator of reads which overlap the given interval list into an iterator of covered single-base loci completely contained within the interval list. To do this, it creates a LocusIteratorByState which will emit a single-bp locus for every base covered by the read iterator, then uses the WindowMakerIterator.advance() to filter down that stream of loci to only those covered by the given interval list. Example: Incoming stream of reads: A:chr20:1-5, B:chr20:2-6, C:chr20:2-7, D:chr20:3-8, E:chr20:5-10 Incoming intervals: chr20:3-7 Locus iterator by state will produce the following stream of data: chr1:1 {A}, chr1:2 {A,B,C}, chr1:3 {A,B,C,D}, chr1:4 {A,B,C,D}, chr1:5 {A,B,C,D,E}, chr1:6 {B,C,D,E}, chr1:7 {C,D,E}, chr1:8 {D,E}, chr1:9 {E}, chr1:10 {E} WindowMakerIterator will then filter the incoming stream, emitting the following stream: chr1:3 {A,B,C,D}, chr1:4 {A,B,C,D}, chr1:5 {A,B,C,D,E}, chr1:6 {B,C,D,E}, chr1:7 {C,D,E} @author mhanna @version 0.1
