Method Detail

newInstance

@Nonnull
public static <T> T newInstance(Class<T> type)

Gets or creates a instance of the given type by using the static method named name.

If the type is annotated by Singleton or by Builder, then the static method identified by the value of the annotation is used to get the instance. Otherwise, the default constructor is used.

Type Parameters:

T - the type of the instance

Parameters:

type - the class to look for

Returns:

the single instance if the type is a singleton, or a new instance

Throws:

ReflectionException - if an error occurs during the instantiation

getAllInterfaces

@Nonnull
public static Set<Class<?>> getAllInterfaces(Class<?> type)

Retrieves all interfaces implemented by the given class and its superclasses.

The order is determined by looking through each interface in turn as declared in the source file and following its hierarchy up. Then each superclass is considered in the same way. Later duplicates are ignored, so the order is maintained.

Parameters:

type - the class to look up

Returns:

a Set of interfaces in order
