Method Detail

values

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

Returns:

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

valueOf

public static JNXServiceFinder 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

findServices

public static <T> Stream<T> findServices(Class<T> serviceClass)

Finds services implementing the provided service class using the context classloader.

Type Parameters:

T - the type of service to load

Parameters:

serviceClass - a Class object representing <T>

Returns:

a Stream of service implementations

findServices

public static <T> Stream<T> findServices(Class<T> serviceClass,
                                         ClassLoader cl)

Finds services implementing the provided service class using the provided classloader.

Type Parameters:

T - the type of service to load

Parameters:

serviceClass - a Class object representing <T>

cl - the ClassLoader to use to load services

Returns:

a Stream of service implementations

findRequiredService

public static <T> T findRequiredService(Class<T> serviceClass,
                                        ClassLoader cl)

Finds a single implementation of the provided service class using the provided classloader, throwing an exception if none can be found.

Type Parameters:

T - the type of service to load

Parameters:

serviceClass - a Class object representing <T>

cl - the ClassLoader to use to load services

Returns:

an instance of the provided service class

Throws:

IllegalStateException - if no implementation can be found
