Method Detail

load

public Iterable<Object> load(Map<String,Object> options,
                             BeanSpec container,
                             Genie genie)

This method will load instances of all public and non-abstract classes that has been annotated by annotation class specified as value in options

Parameters:

options - optional parameters specified to refine the loading process

container - the bean spec about the container into which the bean to be loaded

genie - the dependency injector

Returns:

the list of bean instances

load

protected abstract List<Class<?>> load(Class<? extends Annotation> annoClass,
                                       boolean loadNonPublic,
                                       boolean loadAbstract)

Implementation shall load list of beans whose class is annotated with annoClass specified. The class of all beans returned must have public access

Parameters:

annoClass - the annotation class

loadNonPublic - specify if it should load non public classes

loadAbstract - specify if it should load abstract classes

Returns:

a list of classes that are annotated with annoClass

filter

public org.osgl.Lang.Function filter(Map<String,Object> options,
                                     BeanSpec container)

Returns a predicate check if an object has annotation as specified as hint

Parameters:

options - not used

container - the bean spec of the container into which the element will be loaded

Returns:

a predicate function as described above
