All Implemented Interfaces:

JavaVirtualMachine
```
public class PreUnifiedJavaVirtualMachine
extends AbstractJavaVirtualMachine
```
An implementation of JavaVirtualMachine that uses io.vertx verticles to feed lines to the parser(s) and post events to the aggregators. This implementation is here in the vertx module so that the api and parser modules can exist without having to import io.vertx. In the api module, the class GCToolKit uses the classloader to load required JavaVirtualMachine.

    Parameters:
    
    logFile - the log to be considered. Return true if the JavaVirtualMachine implementation can work with the GC log.
    
    Returns:
    
    true if the JavaVirtualMachine implementation can work with the GC Log.
  - isUnifiedLogging
```
public boolean isUnifiedLogging()
```
    Description copied from interface: JavaVirtualMachine
    
    True if the log is unified or false for preunified
    
    Returns:
    
    true is the log is from JDK 9+
  - isZGC
```
public boolean isZGC()
```
    Description copied from interface: JavaVirtualMachine
    
    Return true if the JVM was using ZGC.

    isZGC in interface JavaVirtualMachine
    
    Overrides:
    
    isZGC in class AbstractJavaVirtualMachine
    
    Returns:
    
    true if the GC is ZGC.
  - isShenandoah
```
public boolean isShenandoah()
```
    Description copied from interface: JavaVirtualMachine
    
    Return true if the JVM was using Shenandoah.
    
    Specified by:
    
    isShenandoah in interface JavaVirtualMachine
    
    Overrides:
    
    isShenandoah in class AbstractJavaVirtualMachine
