Method Detail

getBean

public static <T> T getBean(Class<T> interfaceClass,
                            Class typeClass)

Get a cached singleton object from service map by interface class and generic type class. The serviceMap is constructed from service.yml which defines interface and generic type to implementation mapping.

Type Parameters:

T - class type

Parameters:

interfaceClass - Interface class

typeClass - Generic type class

Returns:

The implementation object

getBean

public static <T> T getBean(Class<T> interfaceClass)

Get a cached singleton object from service map by interface class. The serviceMap is constructed from service.yml which defines interface to implementation mapping. As in the service.yml one interface can have several implementations and that might be the case for this method to get the first one only if there are multiple.

Type Parameters:

T - class type

Parameters:

interfaceClass - Interface class

Returns:

The implementation object

getBeans

public static <T> T[] getBeans(Class<T> interfaceClass)

Get a list of cached singleton objects from service map by interface class. If there is only one object in the serviceMap, then construct the list with this only object.

Type Parameters:

T - class type

Parameters:

interfaceClass - Interface class

Returns:

The array of implementation objects

setBean

public static void setBean(String className,
                           Object object)

This is a testing API that you can manipulate serviceMap by inject an object into it programmatically. It is not recommended to use it for the normal code but just for test cases in order to simulate certain scenarios.

Parameters:

className - full classname with package

object - The object that you want to binding to the class
