public interface PerUnitMetricCollector<BEAN extends htsjdk.samtools.metrics.MetricBase,HKEY extends Comparable,ARGTYPE>
PerRecordCollector - An interface for classes that collect data in order to generate one or more metrics. This process usually occurs in the following fashion: 1. Loop through a data set (usually all records in a BAM file) and call collector.acceptRecord( data ), data in this step is usually added to metrics/Histogram objects 2. Call collector.finish() - perform any final calculations necessary after ALL records have been accepted 3. addMetricsToFile is then used to add any metric(s) or Histogram(s) to the given file BEAN - The Metric type we are generating HKEY - The Key used in any Histograms, use a Wildcard(?) type if there are no Histograms ARGTYPE - Collectors are often used in groups of accumulation levels, in order to avoid recalculating any information needed by multiple collectors we allow different types of arguments that extend DefaultPerRecordCollectorArgs to accommodate any computed values
