Method Details

setCorePoolSize

public void setCorePoolSize(int corePoolSize)

Overrides:

setCorePoolSize in class ThreadPoolExecutor

setMaximumPoolSize

public void setMaximumPoolSize(int maximumPoolSize)

Overrides:

setMaximumPoolSize in class ThreadPoolExecutor

execute

public void execute(Runnable command)

Specified by:

execute in interface Executor

Overrides:

execute in class ThreadPoolExecutor

afterExecute

protected void afterExecute(Runnable r,
 Throwable t)

Overrides:

afterExecute in class ThreadPoolExecutor

getTasks

public Stream<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 String toString()

Overrides:

toString in class ThreadPoolExecutor

remove

public boolean remove(Runnable task)

Overrides:

remove in class ThreadPoolExecutor

appendThreadPoolExecutorDetails

protected void appendThreadPoolExecutorDetails(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 Runnable wrapRunnable(Runnable command)

unwrap

protected Runnable unwrap(Runnable runnable)
