Method Detail

createPool

void createPool(String name,
                int queueSize,
                int maxPoolSize,
                int minPoolSize,
                int priority,
                boolean isDaemon,
                long keepAliveTime,
                String blockPolicy,
                boolean shutdownGraceful,
                int shutdownWaitTime)

Create a shared ThreadPool with a specific ThreadFactory

Parameters:

name - The name of the thread pool

queueSize - The size of the queue

maxPoolSize - The maximum number of threads

minPoolSize - The maximum number of threads

priority - The priority of threads created by this pool. This is one of Thread.MIN_PRIORITY, Thread.NORM_PRIORITY, or Thread.MAX_PRIORITY

isDaemon - Whether or not thread from the pool should run in daemon mode

keepAliveTime - How long should a thread be alive for new work to be done before it is GCed

blockPolicy - What's the blocking policy is resources are exhausted

shutdownGraceful - Should we wait for the queue to finish all pending commands?

shutdownWaitTime - After what time a normal shutdown should take into account if a graceful shutdown has not come to an end

createPool

ThreadPool createPool(int queueSize,
                      int maxPoolSize,
                      int minPoolSize,
                      int priority,
                      boolean isDaemon,
                      long keepAliveTime,
                      String blockPolicy,
                      boolean shutdownGraceful,
                      int shutdownWaitTime)

Create a private ThreadPool with a specific ThreadFactory

Parameters:

queueSize - The size of the queue

maxPoolSize - The maximum number of threads

minPoolSize - The maximum number of threads

priority - The priority of threads created by this pool. This is one of Thread.MIN_PRIORITY, Thread.NORM_PRIORITY, or Thread.MAX_PRIORITY

isDaemon - Whether or not thread from the pool should run in daemon mode

keepAliveTime - How long should a thread be alive for new work to be done before it is GCed

blockPolicy - What's the blocking policy is resources are exhausted

shutdownGraceful - Should we wait for the queue to finish all pending commands?

shutdownWaitTime - After what time a normal shutdown should take into account if a graceful shutdown has not come to an end

Returns:

The newly created ThreadPool
