    • Method Detail

      • threadLocalMap

        public final InternalThreadLocalMap threadLocalMap()
        Returns the internal data structure that keeps the thread-local variables bound to this thread. Note that this method is for internal use only, and thus is subject to change at any time.

      • setThreadLocalMap

        public final void setThreadLocalMap​(InternalThreadLocalMap threadLocalMap)
        Sets the internal data structure that keeps the thread-local variables bound to this thread. Note that this method is for internal use only, and thus is subject to change at any time.

      • willCleanupFastThreadLocals

        public boolean willCleanupFastThreadLocals()
        Returns true if FastThreadLocal.removeAll() will be called once Thread.run() completes.

      • willCleanupFastThreadLocals

        public static boolean willCleanupFastThreadLocals​(java.lang.Thread thread)
        Returns true if FastThreadLocal.removeAll() will be called once Thread.run() completes.

      • permitBlockingCalls

        public boolean permitBlockingCalls()
        Query whether this thread is allowed to perform blocking calls or not. FastThreadLocalThreads are often used in event-loops, where blocking calls are forbidden in order to prevent event-loop stalls, so this method returns false by default.

        Subclasses of FastThreadLocalThread can override this method if they are not meant to be used for running event-loops.

        Returns:
        false, unless overriden by a subclass.
