    • setPoolSize

      public void setPoolSize(int poolSize)
      Set the the maximum number of managed threads.
      Parameters:
      poolSize - the value to set (default is Integer.MAX_VALUE)

    • getPoolSize

      public int getPoolSize()
      Returns:
      the maximum number of managed threads

    • setTaskDecorator

      public void setTaskDecorator(TaskDecorator taskDecorator)
      Specify a custom TaskDecorator to be applied to any Runnable about to be executed.

      Note that such a decorator is not necessarily being applied to the user-supplied Runnable/Callable but rather to the actual execution callback (which may be a wrapper around the user-supplied task).

      The primary use case is to set some execution context around the task's invocation, or to provide some monitoring/statistics for task execution.

      NOTE: Exception handling in TaskDecorator implementations is limited to plain Runnable execution via execute calls. In case of #submit calls, the exposed Runnable will be a FutureTask which does not propagate any exceptions; you might have to cast it and call Future#get to evaluate exceptions. See the ThreadPoolExecutor#afterExecute javadoc for an example of how to access exceptions in such a Future case.

      Parameters:
      taskDecorator - value to set
