Class MemoryAnalyzer

  • All Implemented Interfaces:
    java.lang.Runnable
    public class MemoryAnalyzer
extends TrackableThread
    Tracer for memory usage patterns of Radiance look-and-feel. The tracer is started when RadianceThemingCortex.GlobalScope.setTraceFilename(String) is called before setting Radiance of the look and feel. 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.
