Method Detail

loadAll

public static <T> Iterator<T> loadAll(Class<T> clazz)

Loads all implementations of the given class. The loaded implementations may NOT request the CdsRuntime through CdsRuntimeAware.

Type Parameters:

T - the type

Parameters:

clazz - the class

Returns:

the implementations

loadAll

public static <T> Iterator<T> loadAll(Class<T> clazz,
                                      CdsRuntime runtime)

Loads all implementations of the given class. The loaded implementations may request the CdsRuntime through CdsRuntimeAware.

Type Parameters:

T - the type

Parameters:

clazz - the class

runtime - the CdsRuntime

Returns:

the implementations, initialized with the CdsRuntime

loadSingle

public static <T> T loadSingle(Class<T> clazz)

Loads the first implementation of the given class. The loaded implementation may NOT request the CdsRuntime through CdsRuntimeAware.

Type Parameters:

T - the type

Parameters:

clazz - the class

Returns:

the implementation

loadSingle

public static <T> T loadSingle(Class<T> clazz,
                               CdsRuntime runtime)

Loads the first implementation of the given class. The loaded implementation may request the CdsRuntime through CdsRuntimeAware.

Type Parameters:

T - the type

Parameters:

clazz - the class

runtime - the CdsRuntime

Returns:

the implementation, initialized with the CdsRuntime
