-/**

- * @brief Base class for cross-thread requests made of the fetcher

- *

- * I believe the intent of the LLQueuedThread class was to

- * have these operations derived from LLQueuedThread::QueuedRequest

- * but the texture fetcher has elected to manage the queue

- * in its own manner.  So these are free-standing objects which are

- * managed in simple FIFO order on the mCommands queue of the

- * LLTextureFetch object.

- *

- * What each represents is a simple command sent from an

- * outside thread into the TextureFetch thread to be processed

- * in order and in a timely fashion (though not an absolute

- * higher priority than other operations of the thread).

- * Each operation derives a new class from the base customizing

- * members, constructors and the doWork() method to effect

- * the command.

- *

- * The flow is one-directional.  There are two global instances

- * of the LLViewerAssetStats collector, one for the main program's

- * thread pointed to by gViewerAssetStatsMain and one for the

- * TextureFetch thread pointed to by gViewerAssetStatsThread1.

- * Common operations has each thread recording metrics events

- * into the respective collector unconcerned with locking and

- * the state of any other thread.  But when the agent moves into

- * a different region or the metrics timer expires and a report

- * needs to be sent back to the grid, messaging across threads

- * is required to distribute data and perform global actions.

- * In pseudo-UML, it looks like:

- *

- *                       Main                 Thread1

- *                        .                      .

- *       to the grid.

- * AM  - Agent Moved.  Agent has completed some sort of move to a

- * TE  - Timer Expired.  Metrics timer has expired (on the order

- *       of 10 minutes).

- * CP  - CURL Post

- * MSC - Modify Stats Collector.  State change in the thread-local

- *       collector.  Typically a region change which affects the

- *       global pointers used to find the 'current stats'.

- * RSC - Read Stats Collector.  Extract collector data cloning it

- *       (i.e. deep copy) when necessary.

+// Cross-thread messaging for asset metrics.
+
+/**
+ * @brief Base class for cross-thread requests made of the fetcher
+ *
+ * I believe the intent of the LLQueuedThread class was to
+ * have these operations derived from LLQueuedThread::QueuedRequest
+ * but the texture fetcher has elected to manage the queue
+ * in its own manner.  So these are free-standing objects which are
+ * managed in simple FIFO order on the mCommands queue of the
+ * LLTextureFetch object.
+ *
+ * What each represents is a simple command sent from an
+ * outside thread into the TextureFetch thread to be processed
+ * in order and in a timely fashion (though not an absolute
+ * higher priority than other operations of the thread).
+ * Each operation derives a new class from the base customizing
+ * members, constructors and the doWork() method to effect
+ * the command.
+ *
+ * The flow is one-directional.  There are two global instances
+ * of the LLViewerAssetStats collector, one for the main program's
+ * thread pointed to by gViewerAssetStatsMain and one for the
+ * TextureFetch thread pointed to by gViewerAssetStatsThread1.
+ * Common operations has each thread recording metrics events
+ * into the respective collector unconcerned with locking and
+ * the state of any other thread.  But when the agent moves into
+ * a different region or the metrics timer expires and a report
+ * needs to be sent back to the grid, messaging across threads
+ * is required to distribute data and perform global actions.
+ * In pseudo-UML, it looks like:
+ *
+ *                       Main                 Thread1
