-// 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
- *                        .                      .

- *       thread's local stats, converts to LLSD and sends it on
- *       to the grid.
- * AM  - Agent Moved.  Agent has completed some sort of move to a
- *       new region.
- * 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.

+

+/**

+ * @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
