Class OverlapUsageRecordQueryMapper<K,D extends java.lang.Number>

java.lang.Object

uk.ac.ed.epcc.safe.accounting.charts.UsageRecordQueryMapper<K>

uk.ac.ed.epcc.safe.accounting.charts.OverlapUsageRecordQueryMapper<K,D>

Type Parameters:

K - type of key

D - type of data

All Implemented Interfaces:

uk.ac.ed.epcc.webapp.charts.strategy.Labelled, uk.ac.ed.epcc.webapp.charts.strategy.LabelledQueryMapper<UsageProducer<?>>, uk.ac.ed.epcc.webapp.charts.strategy.PlotStrategy, uk.ac.ed.epcc.webapp.charts.strategy.QueryMapper<UsageProducer<?>>

public class OverlapUsageRecordQueryMapper<K,D extends java.lang.Number>
extends UsageRecordQueryMapper<K>

QueryMapper that plots property data using the OverlapHandler overlap methods Note that this may be inefficient if used in a TimeChart as the overlap records will be processed multiple times.
