Enum Constant Detail

SINGLE_THREAD

public static final ExecutionModel SINGLE_THREAD

Only one thread is shared by all instances (slow).

STATIC_THREAD_POOL

public static final ExecutionModel STATIC_THREAD_POOL

Threads are taken from a static pool.

Some slow thread might lock up the pool and other processes might be slowed down.

ThreadPoolExecutor

THREAD_PER_INSTANCE

public static final ExecutionModel THREAD_PER_INSTANCE

One thread per instance of class. Slow but each instance can work in isolation. Also if some thread is not correctly closed there might be threads leaks.

Method Detail

values

public static ExecutionModel[] 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 (ExecutionModel c : ExecutionModel.values())
    System.out.println(c);

Returns:

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

valueOf

public static ExecutionModel 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
