-/**
- * @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:

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 + * . . + * . . + * +-----+ . + * | AM | . + * +--+--+ . + * +-------+ | . + * | Main | +--+--+ . + * | | | SRE |---. . + * | Stats | +-----+ \ . + * | | | \ (uuid) +-----+ + * | Coll. | +--+--+ `-------->| SR | + * +-------+ | MSC | +--+--+ + * | ^ +-----+ | + * | | (uuid) / . +-----+ (uuid) + * | `--------' . | MSC |---------. + * | . +-----+ | + * | +-----+ . v + * | | TE | . +-------+ + * | +--+--+ . | Thd1 | + * | | . | | + * | +-----+ . | Stats | + * `--------->| RSC | . | | + * +--+--+ . | Coll. | + * | . +-------+ + * +--+--+ . | + * | SME |---. . | + * +-----+ \ . | + * . \ (clone) +-----+ | + * . `-------->| SM | | + * . +--+--+ | + * . | | + * . +-----+ | + * . | RSC |<--------' + * . +-----+ + * . | + * . +-----+ + * . | CP |--> HTTP POST + * . +-----+ + * . . + * . . + * + * + * Key: + * + * SRE - Set Region Enqueued.
