Method Detail

terminated

protected void terminated()

Overrides:

terminated in class ThreadPoolExecutor

startSchedule

public void startSchedule()

stopSchedule

public void stopSchedule()

beforeExecute

protected void beforeExecute(Thread t,
                             Runnable r)

Overrides:

beforeExecute in class ThreadPoolExecutor

afterExecute

protected void afterExecute(Runnable r,
                            Throwable t)

Overrides:

afterExecute in class ThreadPoolExecutor

run

public void run()

Specified by:

run in interface Runnable

getAllStackTrace

public String getAllStackTrace()

traceIdSafari

protected String traceIdSafari(Thread t)

Search in thread t for traceId if used in SOFA-RPC context. This method is protected in that subclass may need to customized logic. Using reflection not only because threadLocal fields of thread are private, but also we don't want to introduce tracer dependency.

Parameters:

t - the thread

Returns:

traceId, maybe null if not found

getThreadPoolName

public String getThreadPoolName()

setThreadPoolName

public void setThreadPoolName(String threadPoolName)

setPeriod

public void setPeriod(long period)

getTaskTimeout

public long getTaskTimeout()

setTaskTimeout

public void setTaskTimeout(long taskTimeout)

getTimeUnit

public TimeUnit getTimeUnit()

getPeriod

public long getPeriod()
