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 every X
seconds. The
X
(delay) is specified in the constructor. This class is for
internal use only.-
