Class SAMRecordSetBuilder

java.lang.Object

htsjdk.samtools.SAMRecordSetBuilder

All Implemented Interfaces:

java.lang.Iterable<SAMRecord>

public class SAMRecordSetBuilder
extends java.lang.Object
implements java.lang.Iterable<SAMRecord>

Factory class for creating SAMRecords for testing purposes. Various methods can be called to add new SAM records (or pairs of records) to a list which can then be returned at any point. The records must reference human chromosomes (excluding randoms etc.).

Although this is a class for testing, it is in the src tree because it is included in the sam jarfile.

Construct a new SAMRecordSetBuilder.

Parameters:

sortOrder - If sortForMe, defines the sort order.

sortForMe - If true, keep the records created in sorted order.
