```
    Parameters:
    
    index - the identifier of this garbage collection which is the number of collections that this collector has done
    
    startTime - the start time of the collection in milliseconds since the Java virtual machine was started.
    
    endTime - the end time of the collection in milliseconds since the Java virtual machine was started.
