org.pushingpixels.substance.internal.utils.MemoryAnalyzer

All Implemented Interfaces:

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