In the latter case, 413 tasks will run serially on the calling thread. Tasks are run to 414 completion before a <code>Future</code> is returned to the caller (unless the 415 executor has been shutdown). 416 417 <p>Although all tasks are immediately executed in the thread that 418 submitted the task, this <code>ExecutorService</code> imposes a small 419 locking overhead on each task submission in order to implement shutdown 420 and termination behavior. 421 422 <p>The implementation deviates from the <code>ExecutorService</code> 423 specification with regards to the <code>shutdownNow</code> method. First, 424 "best-effort" with regards to canceling running tasks is implemented 425 as "no-effort". No interrupts or other attempts are made to stop 426 threads executing tasks. Second, the returned list will always be empty, 427 as any submitted task is considered to have started execution. 428 This applies also to tasks given to <code>invokeAll</code> or <code>invokeAny</code> 429 which are pending serial execution, even the subset of the tasks that 430 have not yet started execution. It is unclear from the 431 <code>ExecutorService</code> specification if these should be included, and 432 it's much easier to implement the interpretation that they not be. 433 Finally, a call to <code>shutdown</code> or <code>shutdownNow</code> may result 434 in concurrent calls to <code>invokeAll/invokeAny</code> throwing 435 RejectedExecutionException, although a subset of the tasks may already 436 have been executed. 437 <P> 438 <DD><DL> 439 </DL> 440 </DD> 441 </DL> 442 <!-- ========= END OF CLASS DATA ========= --> 443 <HR> 444 445 446 <!-- ======= START OF BOTTOM NAVBAR ====== --> 447 <A NAME="navbar_bottom"><!-- --></A> 448 <A HREF="#skip-navbar_bottom" title="Skip navigation links"></A> 449 <TABLE BORDER="0" WIDTH="100%" CELLPADDING="1" CELLSPACING="0" SUMMARY=""> 450 <TR> 451 <TD COLSPAN=2 BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> 452 <A NAME="navbar_bottom_firstrow"><!-- --></A> 453 <TABLE BORDER="0" CELLPADDING="0" CELLSPACING="3" SUMMARY=""> 454 <TR ALIGN="center" VALIGN="top"> 455 <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../../../overview-summary.html"><FONT CLASS="NavBarFont1"><B>Overview</B></FONT></A> </TD> 456 <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="package-summary.html"><FONT CLASS="NavBarFont1"><B>Package</B></FONT></A> </TD> 457 <TD BGCOLOR="#FFFFFF" CLASS="NavBarCell1Rev"> <FONT CLASS="NavBarFont1Rev"><B>Class</B></FONT> </TD> 458 <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="class-use/Executors.html"><FONT CLASS="NavBarFont1"><B>Use</B></FONT></A> </TD> 459 <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="package-tree.html"><FONT CLASS="NavBarFont1"><B>Tree</B></FONT></A> </TD> 460 <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../../../deprecated-list.html"><FONT CLASS="NavBarFont1"><B>Deprecated</B></FONT></A> </TD> 461 <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../../../index-all.html"><FONT CLASS="NavBarFont1"><B>Index</B></FONT></A> </TD> 462 <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../../../../help-doc.html"><FONT CLASS="NavBarFont1"><B>Help</B></FONT></A> </TD> 463 </TR> 464 </TABLE> 465 </TD> 466 <TD ALIGN="right" VALIGN="top" ROWSPAN=3><EM> 467 </EM> 468 </TD> 469 </TR> 470 471 <TR> 472 <TD BGCOLOR="white" CLASS="NavBarCell2"><FONT SIZE="-2"> 473 <A HREF="../../../../../com/google/common/util/concurrent/ExecutionList.html" title="class in com.google.common.util.concurrent"><B>PREV CLASS</B></A> 474 <A HREF="../../../../../com/google/common/util/concurrent/FakeTimeLimiter.html" title="class in com.google.common.util.concurrent"><B>NEXT CLASS</B></A></FONT></TD> 475 <TD BGCOLOR="white" CLASS="NavBarCell2"><FONT SIZE="-2"> 476 <A HREF="../../../../../index.html?com/google/common/util/concurrent/Executors.html" target="_top"><B>FRAMES</B></A> 477 <A HREF="Executors.html" target="_top"><B>NO FRAMES</B></A> 478 <SCRIPT type="text/javascript"> 479 <!-- 480 if(window==top) { 481 document.writeln('<A HREF="../../../../../allclasses-noframe.html"><B>All Classes</B></A>'); 482 } 483 //--> 484 </SCRIPT> 485 <NOSCRIPT> 486 <A HREF="../../../../../allclasses-noframe.html"><B>All Classes</B></A> 487 </NOSCRIPT> 488 489 490 </FONT></TD> 491 </TR> 492 <TR> 493 <TD VALIGN="top" CLASS="NavBarCell3"><FONT SIZE="-2"> 494 SUMMARY: NESTED | FIELD | <A HREF="#constructor_summary">CONSTR</A> | <A HREF="#method_summary">METHOD</A></FONT></TD> 495 <TD VALIGN="top" CLASS="NavBarCell3"><FONT SIZE="-2"> 496 DETAIL: FIELD | <A HREF="#constructor_detail">CONSTR</A> | <A HREF="#method_detail">METHOD</A></FONT></TD> 497 </TR> 498 </TABLE> 499 <A NAME="skip-navbar_bottom"></A> 500 <!-- ======== END OF BOTTOM NAVBAR ======= --> 501 502 <HR> 503 504 </BODY> 505 </HTML> 506
