Runnable
public class MemoryAnalyzer extends org.pushingpixels.lafwidget.utils.TrackableThread
Tracer for memory usage patterns of Substance look-and-feel. The tracer is started when VM has-Dsubstancelaf.traceFile
flag. The value of this flag specifies the location of trace log file. When activated, the tracer runs a thread that collects information on memory usage and appends it to the trace log file everyX
seconds. TheX
(delay) is specified in the constructor. This class is for internal use only.
