[KIEKER-533] FS Readers terminate immediately on unknown types

[rju]

JIRA Issue: KIEKER-533 FS Readers terminate immediately on unknown types Original Reporter: Andre van Hoorn

---

FSReaders do provide the property "readOnlyRecordsOfType"; however, this functionality doesn't work any more. Also, thanks to the new pipe-and-filter framework, it also isn't required to have this feature any longer.

1. We will remove this property
and
2. Add a new property "ignoreUnknownRecordTypes" which defaults to false. If the property is set to false, the behavior is exactly like the current one. If true, the reader ignore records of this type and proceeds.

The TraceAnalysisTool configures the FSReader to ignore unknown types (9f87071ae76c99bb36054f84cb6ad9ef0e50611a).

Tested by

1. Executing the main in BookstoreEventRecordFactory
1. Manipulating the kieker.map
{{

{ avanhoornavanhoorn-thinkpad:0:~/git_work/kieker <master> $ cat /tmp/kieker-20120330-201321543-UTC-avanhoorn-thinkpad-KIEKER-SINGLETON/kieker.map $0=kieker.common.record.flow.trace.TraceXY $1=kieker.common.record.flow.trace.operation.BeforeOperationEvent $2=kieker.common.record.flow.trace.operation.AfterOperationEvent $3=kieker.common.record.flow.trace.operation.CallOperationEvent }

}}
1. Executing the TraceAnalysis tool

avanhoornavanhoorn-thinkpad:0:~/git_work/kieker <master> $ bin/trace-analysis.sh -i /tmp/kieker-20120330-201321543-UTC-avanhoorn-thinkpad-KIEKER-SINGLETON/ -o tmp/ -p 23- --plot-Aggregated-Deployment-Call-Tree --plot-Aggregated-Assembly-Call-Tree

4. Inspecting the log.
