execute

public void execute(Runnable r)

Throws:

InterruptedException

getQueue

@Deprecated
public Queue<Runnable> getQueue()

Deprecated. please use getConfiguration() to check thread pool configuration settings.

Description copied from interface: ExtendedThreadPool

Returns the task queue used by this executor. Access to the task queue is intended primarily for debugging and monitoring. This queue may be in active use. Retrieving the task queue does not prevent queued tasks from executing.

Specified by:

getQueue in interface ExtendedThreadPool

Returns:

the task queue

getActiveCount

@Deprecated
public int getActiveCount()

Deprecated. please use ThreadPoolMonitoringProbes to intercept thread pool events and build statistics.

Description copied from interface: ExtendedThreadPool

Returns the approximate number of threads that are actively executing tasks.

Specified by:

getActiveCount in interface ExtendedThreadPool

Returns:

the number of threads

getTaskCount

@Deprecated
public int getTaskCount()

Deprecated. please use ThreadPoolMonitoringProbes to intercept thread pool events and build statistics.

Description copied from interface: ExtendedThreadPool

Returns the approximate total number of tasks that have been scheduled for execution. Because the states of tasks and threads may change dynamically during computation, the returned value is only an approximation, but one that does not ever decrease across successive calls.

Specified by:

getTaskCount in interface ExtendedThreadPool

Returns:

the number of tasks

getCompletedTaskCount

@Deprecated
public long getCompletedTaskCount()

Deprecated. please use ThreadPoolMonitoringProbes to intercept thread pool events and build statistics.

Description copied from interface: ExtendedThreadPool

Returns the approximate total number of tasks that have completed execution. Because the states of tasks and threads may change dynamically during computation, the returned value is only an approximation, but one that does not ever decrease across successive calls.

Specified by:

getCompletedTaskCount in interface ExtendedThreadPool

Returns:

the number of tasks

getCorePoolSize

@Deprecated
public int getCorePoolSize()

Deprecated. please use getConfiguration() to check thread pool configuration settings.

Description copied from interface: ExtendedThreadPool

Returns the core number of threads.

Specified by:

getCorePoolSize in interface ExtendedThreadPool

Returns:

the core number of threads

See Also:

ExtendedThreadPool.setCorePoolSize(int)

setCorePoolSize

@Deprecated
public void setCorePoolSize(int corePoolSize)

Deprecated. please use reconfigure(com.sun.grizzly.util.ThreadPoolConfig) to change thread pool configuration settings.

Description copied from interface: ExtendedThreadPool

Sets the core number of threads. This overrides any value set in the constructor. If the new value is smaller than the current value, excess existing threads will be terminated when they next become idle. If larger, new threads will, if needed, be started to execute any queued tasks.

Specified by:

setCorePoolSize in interface ExtendedThreadPool

Parameters:

corePoolSize - the new core size

See Also:

ExtendedThreadPool.getCorePoolSize()

getLargestPoolSize

@Deprecated
public int getLargestPoolSize()

Deprecated. please use ThreadPoolMonitoringProbes to intercept thread pool events and build statistics.

Description copied from interface: ExtendedThreadPool

Returns the largest number of threads that have ever simultaneously been in the pool.

Specified by:

getLargestPoolSize in interface ExtendedThreadPool

Returns:

the number of threads

getPoolSize

@Deprecated
public int getPoolSize()

Deprecated. please use ThreadPoolMonitoringProbes to intercept thread pool events and build statistics.

Description copied from interface: ExtendedThreadPool

Returns the current number of threads in the pool.

Specified by:

getPoolSize in interface ExtendedThreadPool

Returns:

the number of threads

getQueueSize

@Deprecated
public int getQueueSize()

Deprecated. please use ThreadPoolMonitoringProbes to intercept thread pool events and build statistics.

Description copied from interface: ExtendedThreadPool

Returns the number of tasks, which are currently waiting in the queue.

Specified by:

getQueueSize in interface ExtendedThreadPool

Returns:

the number of tasks, which are currently waiting in the queue.

getKeepAliveTime

@Deprecated
public long getKeepAliveTime(TimeUnit unit)

Deprecated. please use getConfiguration() to check thread pool configuration settings.

Description copied from interface: ExtendedThreadPool

Returns the thread keep-alive time, which is the amount of time which threads in excess of the core pool size may remain idle before being terminated.

Specified by:

getKeepAliveTime in interface ExtendedThreadPool

Parameters:

unit - the desired time unit of the result

Returns:

the time limit

See Also:

ExtendedThreadPool.setKeepAliveTime(long, java.util.concurrent.TimeUnit)

setKeepAliveTime

@Deprecated
public void setKeepAliveTime(long time,
                                        TimeUnit unit)

Deprecated. please use reconfigure(com.sun.grizzly.util.ThreadPoolConfig) to change thread pool configuration settings.

Description copied from interface: ExtendedThreadPool

Sets the time limit for which threads may remain idle before being terminated. If there are more than the core number of threads currently in the pool, after waiting this amount of time without processing a task, excess threads will be terminated. This overrides any value set in the constructor.

Specified by:

setKeepAliveTime in interface ExtendedThreadPool

Parameters:

time - the time to wait. A time value of zero will cause excess threads to terminate immediately after executing tasks.

unit - the time unit of the time argument

See Also:

ExtendedThreadPool.getKeepAliveTime(java.util.concurrent.TimeUnit)

getMaximumPoolSize

@Deprecated
public int getMaximumPoolSize()

Deprecated. please use getConfiguration() to check thread pool configuration settings.

Description copied from interface: ExtendedThreadPool

Returns the maximum allowed number of threads.

Specified by:

getMaximumPoolSize in interface ExtendedThreadPool

Returns:

the maximum allowed number of threads

See Also:

ExtendedThreadPool.setMaximumPoolSize(int)

setMaximumPoolSize

@Deprecated
public void setMaximumPoolSize(int maximumPoolSize)

Deprecated. please use reconfigure(com.sun.grizzly.util.ThreadPoolConfig) to change thread pool configuration settings.

Description copied from interface: ExtendedThreadPool

Sets the maximum allowed number of threads. This overrides any value set in the constructor. If the new value is smaller than the current value, excess existing threads will be terminated when they next become idle.

Specified by:

setMaximumPoolSize in interface ExtendedThreadPool

Parameters:

maximumPoolSize - the new maximum

See Also:

ExtendedThreadPool.getMaximumPoolSize()
