Method Detail

shutdown

public void shutdown(EsThreadPoolExecutor.ShutdownListener listener)

terminated

protected void terminated()

Overrides:

terminated in class java.util.concurrent.ThreadPoolExecutor

execute

public void execute(java.lang.Runnable command)

Specified by:

execute in interface java.util.concurrent.Executor

Overrides:

execute in class java.util.concurrent.ThreadPoolExecutor

doExecute

protected void doExecute(java.lang.Runnable command)

afterExecute

protected void afterExecute(java.lang.Runnable r,
                            java.lang.Throwable t)

Overrides:

afterExecute in class java.util.concurrent.ThreadPoolExecutor

getTasks

public java.util.stream.Stream<java.lang.Runnable> getTasks()

Returns a stream of all pending tasks. This is similar to ThreadPoolExecutor.getQueue() but will expose the originally submitted Runnable instances rather than potentially wrapped ones.

toString

public final java.lang.String toString()

Overrides:

toString in class java.util.concurrent.ThreadPoolExecutor

appendThreadPoolExecutorDetails

protected void appendThreadPoolExecutorDetails(java.lang.StringBuilder sb)

Append details about this thread pool to the specified StringBuilder. All details should be appended as key/value pairs in the form "%s = %s, "

Parameters:

sb - the StringBuilder to append to

wrapRunnable

protected java.lang.Runnable wrapRunnable(java.lang.Runnable command)

unwrap

protected java.lang.Runnable unwrap(java.lang.Runnable runnable)
