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.
