    Enclosing class:
    BoundedLocalCache<K,​V>
    static final class BoundedLocalCache.PerformCleanupTask
extends java.util.concurrent.ForkJoinTask<java.lang.Void>
implements java.lang.Runnable
    A reusable task that performs the maintenance work; used to avoid wrapping by ForkJoinPool.

    • Method Summary

      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      boolean cancel​(boolean mayInterruptIfRunning)  
      void complete​(java.lang.Void value)  
      void completeExceptionally​(java.lang.Throwable ex)  
      boolean exec()  
      java.lang.Void getRawResult()
      This method cannot be ignored due to being final, so a hostile user supplied Executor could forcibly complete the task and halt future executions.
      void run()  
      void setRawResult​(java.lang.Void v)

      • exec

        public boolean exec()
        Specified by:
        exec in class java.util.concurrent.ForkJoinTask<java.lang.Void>

      • run

        public void run()
        Specified by:
        run in interface java.lang.Runnable

      • getRawResult

        public java.lang.Void getRawResult()
        This method cannot be ignored due to being final, so a hostile user supplied Executor could forcibly complete the task and halt future executions. There are easier ways to intentionally harm a system, so this is assumed to not happen in practice.
