Method Summary

Modifier and Type	Method and Description
static void	execute(Runnable command) Deprecated. it should not be allowed for a "general-purpose" pool to increase in size infinitely and thus may be able to break an application just because of allowing to many threads to run concurrently.
static void	executeSequentially(Runnable command) Deprecated. if there is a need for an execution queue it is not likely that it's focus has to be global. Additionally it is better to think about the purpose of the sequential execution and then to narrow it down to the tasks that are really dependent on each other (because that's the whole point of sequential execution). Maybe other solutions for the issue may be even more suited and/or elegant, too.
static void	shutdown() Deprecated. shutdown immediately renders this global pool unusable. It can never be revived. Thus any call to this operation is dangerous for any piece of code that depends on this implementation.
static List<Runnable>	shutdownNow() Deprecated. shutdown immediately renders this global pool unusable. It can never be revived. Thus any call to this operation is dangerous for any piece of code that depends on this implementation.
static Future<?>	submit(Runnable command) Deprecated. it should not be allowed for a "general-purpose" pool to increase in size infinitely and thus may be able to break an application just because of allowing to many threads to run concurrently.

Method Detail

execute

public static void execute(Runnable command)

Deprecated. it should not be allowed for a "general-purpose" pool to increase in size infinitely and thus may be able to break an application just because of allowing to many threads to run concurrently.

Executes the given runnable in the applications common cached threadpool. Notice: It is smarter to pass plain Runnables instead of Threads as arguments, as one purpose of this pool is minimizing thread creation overhead.

Parameters:

command - given runnable

executeSequentially

public static void executeSequentially(Runnable command)

Deprecated. if there is a need for an execution queue it is not likely that it's focus has to be global. Additionally it is better to think about the purpose of the sequential execution and then to narrow it down to the tasks that are really dependent on each other (because that's the whole point of sequential execution). Maybe other solutions for the issue may be even more suited and/or elegant, too.

Executes the given runnable in the applications threadpool. All threads, which will be started with this method will be run sequentially.

Parameters:

command - given runnable

submit

public static Future<?> submit(Runnable command)

Deprecated. it should not be allowed for a "general-purpose" pool to increase in size infinitely and thus may be able to break an application just because of allowing to many threads to run concurrently.

Submits the given runnable in the applications common cached threadpool.

Parameters:

command - given runnable

Returns:

a Future representing pending completion of the runnable

shutdownNow

public static List<Runnable> shutdownNow()

Deprecated. shutdown immediately renders this global pool unusable. It can never be revived. Thus any call to this operation is dangerous for any piece of code that depends on this implementation.

Attempts to stop all actively executing tasks, halts the processing of waiting tasks, and returns a list of the tasks that were awaiting execution.

Returns:

list

shutdown

public static void shutdown()

Deprecated. shutdown immediately renders this global pool unusable. It can never be revived. Thus any call to this operation is dangerous for any piece of code that depends on this implementation.

Initiates an orderly shutdown in which previously submitted tasks are executed, but no new tasks will be accepted.
