PreUnifiedDiarizer (GCToolKit Parser 3.0.4 API)

java.lang.Object
- com.microsoft.gctoolkit.parser.jvm.PreUnifiedDiarizer

All Implemented Interfaces:

Diarizer
```
public class PreUnifiedDiarizer
extends Object
implements Diarizer
```
Class to answer 3 questions about the GC log; - which collector combination is being used - which JVM version - which flags are being used
Collectors - Unknown (no details) - Serial - ParNew/CMS - iCMS - PSYoungGen/PSFull - G1GC
Version breaks Can be known precisely if header is present in GC log. prior to 1.7.0_45 1.7.0_45 has the System.gc() regression 1.8.0_05 anything after this version will include G1 Metaspace clause 1.9.0 unknown how to determine this via deriveConfiguration.
Are these flags set PrintGCDetails PrintTenuringDistrubtion PrintGCApplicationStoppedTime PrintGCApplicationConcurrentTime
Log file characteristics
pre 7.0_45 - Permspace - (System)
7.0_45+ - (System.gc()) - Permspace
8.0 - Metaspace
8.0_20 - G1 prints Metaspace clause
Collector clues iCMS - CMS cycle starts early but once completed all further records will contain "icms_dc="
ParNew/CMS - ParNew - initial-mark
PSYoung/PSFull - PSYoungGen - PSFull
Serial - DefNew
