定義:

cancel インタフェース内 Cancelable

isCancelRequested

public boolean isCancelRequested()

定義:

isCancelRequested インタフェース内 Cancelable

getAsynchronousThreadDump

public java.util.List<AsyncTaskInfo> getAsynchronousThreadDump()

getAsynchronousThreadDumpAsString

public java.lang.String getAsynchronousThreadDumpAsString()

eventLoop

public boolean eventLoop()
                  throws java.lang.Throwable

Execute all queued tasks. If execution of those tasks result in addition of new tasks to the queue execute them as well.

Unless there are external dependencies or bugs single call to this method performs the complete asynchronous execution.

In presence of external dependencies it is expected that eventLoop() is called every time after change in their state can unblock the asynchronous execution.

戻り値:

true means there are no tasks originated from this scope that are not done yet.

isComplete

public boolean isComplete()

getFailure

public java.lang.Throwable getFailure()

doAsync

protected abstract void doAsync()
                         throws java.lang.Throwable
