Constructor Detail

DefaultThreadPool

public DefaultThreadPool(int poolSize,
                         boolean syncThreads)

Create a new pool.

Method Detail

configure

public void configure(int poolSize)

Configure a new pool size.

close

public void close()

Close the pool i.e, stop pooling threads. Note that subsequently, task will still be executed but no pooling is taking place anymore.

executeTask

public void executeTask(java.lang.Runnable task)

Execute the task in a free thread or create a new one.

Parameters:

task - The task to execute
