java.lang.Object

com.neurosys.etl.web.transformers.WebAnalyticsTransformer

com.neurosys.etl.web.transformers.WebAnalyticsParamSpecificTransformer

All Implemented Interfaces:

org.apache.commons.collections.Transformer

public class WebAnalyticsParamSpecificTransformer
extends WebAnalyticsTransformer

A WebAnalyticsTransformer that only measures based on filterParam over the HttpServletRequest.
The #predicate works as a filter. If the filterParam value exists in session or user-agent cookie, it will not consider as new.

The Default filterParam is Googles utm_campaign, to identify if the user-agent or session is new "for" the campaign or not.
