All Implemented Interfaces:

CollectionMeasurement, Measurement

Direct Known Subclasses:

ContextAccumulatorMeasurement, SubMetricsAccumulatorMeasurement

public abstract class AccumulatorMeasurement

extends MeasurementBase

implements CollectionMeasurement

Base class that accumulates entries, filtering with regular expressions. If no regular expressions are given, matches everything for the given measurement, which must implement the CollectionMeasurement interface. Regular expressions matching using Perl5Util from Jakarta-ORO. This measurement will use Perl5Util.group(1) if not null, otherwise the full string.

This is the syntax for initializing this type of measurement:

  <init>
      measurement name [perl regular expression]
      ...
  </init>
