Method Detail

resolveDependency

<T> T resolveDependency(Class<T> type)
                 throws IllegalArgumentException

Tries to resolve a dependency that matches a given class. No specific DependencyResolver.SelectionStrategy is used, so the first encountered matching dependency will be returned.

Type Parameters:

T - the type that the returned instance must implement

Parameters:

type - the type of Class that the returned instance must implement.

Returns:

the resolved dependency for the given type.

Throws:

IllegalArgumentException - if no matching dependency was found.

resolveDependency

<T> T resolveDependency(Class<T> type,
                        DependencyResolver.SelectionStrategy selector)
                 throws IllegalArgumentException

Tries to resolve a dependency that matches a given class. All candidates are fed to the selector which ultimately becomes responsible for making the choice between all available candidates.

Type Parameters:

T - the type that the returned instance must implement

Parameters:

type - the type of Class that the returned instance must implement.

selector - DependencyResolver.SelectionStrategy which will make the choice of which one to return among matching candidates.

Returns:

the resolved dependency for the given type.

Throws:

IllegalArgumentException - if no matching dependency was found.

resolveTypeDependencies

default <T> Iterable<? extends T> resolveTypeDependencies(Class<T> type)

Tries to resolve a dependencies that matches a given class.

Type Parameters:

T - the type that the returned instance must implement

Parameters:

type - the type of Class that the returned instances must implement.

Returns:

the list of resolved dependencies for the given type.
