Method Details

getImplClasses

public static <T> List<Class<?>> getImplClasses(Class<T> clazz)

Acquires the list of implementation classes when multiple classes may be provided.

Type Parameters:

T - The interface type.

Parameters:

clazz - The class representing the interface for which to look for registered implementations.

Returns:

The list of types provided. Ordering is based on classloader behavior and should not be depended upon. (never null)

getSingleImpl

public static <T> T getSingleImpl(Class<T> clazz,
 ArgPair<?>... args)

Acquires the implementation when one and only one implementation is expected. Provides an instance if the first instance encountered is instantiable. Logs warnings if there are more than 1 impls available. Returned impl type is based upon classloader behavior and may be non-deterministic.

Type Parameters:

T - The interface type.

Parameters:

clazz - The class representing the Interface for which to look for registered implementations.

Returns:

A instance of the impl created using the no-argument constructor.

Throws:
