Enum Constant Detail

FIXED

public static final ThreadPool.PoolPolicy FIXED

Maintain a fixed thread pool. The threads will be started immediately, and will terminate only if ThreadPool.shutdown() or ThreadPool.shutdownNow() are called.

See Also:

Executors.newFixedThreadPool(int)

CACHED

public static final ThreadPool.PoolPolicy CACHED

Maintain a "cached" thread pool. Threads will be created on-demand, but will be kept alive for re-use when all jobs are processed. However, they will be terminated when they have been idle for 60 seconds.

Note that as opposed to Executors.newCachedThreadPool(), the specified pool size will never be exceeded.

See Also:

Executors.newCachedThreadPool()

Method Detail

values

public static ThreadPool.PoolPolicy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ThreadPool.PoolPolicy c : ThreadPool.PoolPolicy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ThreadPool.PoolPolicy valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
