## org.jvnet.substance.utils
Class MemoryAnalyzer

    java.lang.Object
      java.lang.Thread
          org.jvnet.lafwidget.utils.TrackableThread
              org.jvnet.substance.utils.MemoryAnalyzer

All Implemented Interfaces:
  java.lang.Runnable

    public class MemoryAnalyzer

extends org.jvnet.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.

### enqueueUsage

    public static void enqueueUsage(java.lang.String usage)

  Adds usage string.

  Parameters:
    `usage` - Usage string. Will be output to the trace file at next iteration of the tracer.

### getUsages
