Class MeasureId

java.lang.Object
  ch.elca.el4j.services.statistics.detailed.MeasureId

All Implemented Interfaces:

Serializable

public class MeasureId
extends Object
implements Serializable

A MeasureID uniquely identifies a global measure.

The ID of a measure is made unique through :

• the hostname of the machine
• the invocation time of the method

Remark : the sequential number associated to each measure is not part of the measure ID. The ID of the measure is reused during the whole lifetime of an end-to-end measure (global measure with all its sub-measures). The sequential number will be increased for each sub-measure. This class was ported from Leaf 2. Original authors: YMA, DBA. Leaf2 package name: ch.elca.leaf.services.measuring
