Public Constructors
	AbstractServiceLoaderBasedFactoryBean()

Public Methods
Class	getServiceType() Return the desired service type.
void	setBeanClassLoader(ClassLoader beanClassLoader) Callback that supplies the bean `class loader` to a bean instance.
void	setServiceType(Class serviceType) Specify the desired service type (typically the service's public API).

Protected Methods
Object	createInstance() Delegates to `getObjectToExpose(java.util.ServiceLoader)`.
abstract Object	getObjectToExpose(ServiceLoader serviceLoader) Determine the actual object to expose for the given ServiceLoader.

Inherited Methods

From class org.springframework.beans.factory.config.AbstractFactoryBean

void	afterPropertiesSet() Eagerly create the singleton instance, if necessary.
abstract T	createInstance() Template method that subclasses must override to construct the object returned by this factory.
void	destroy() Destroy the singleton instance, if any.
void	destroyInstance(T instance) Callback for destroying a singleton instance.
BeanFactory	getBeanFactory() Return the BeanFactory that this bean runs in.
TypeConverter	getBeanTypeConverter() Obtain a bean type converter from the BeanFactory that this bean runs in.
Class[]	getEarlySingletonInterfaces() Return an array of interfaces that a singleton object exposed by this FactoryBean is supposed to implement, for use with an 'early singleton proxy' that will be exposed in case of a circular reference.
final T	getObject() Expose the singleton instance or create a new prototype instance.
abstract Class<?>	getObjectType() This abstract method declaration mirrors the method in the FactoryBean interface, for a consistent offering of abstract template methods.
boolean	isSingleton() Is the object managed by this factory a singleton? That is, will `getObject()` always return the same object (a reference that can be cached)? NOTE: If a FactoryBean indicates to hold a singleton object, the object returned from `getObject()` might get cached by the owning BeanFactory.
void	setBeanClassLoader(ClassLoader classLoader) Callback that supplies the bean `class loader` to a bean instance.
void	setBeanFactory(BeanFactory beanFactory) Callback that supplies the owning factory to a bean instance.
void	setSingleton(boolean singleton) Set if a singleton should be created, or a new object on each request otherwise.

Public Constructors

public AbstractServiceLoaderBasedFactoryBean ()

Also: SpringBeans

Public Methods

public Class getServiceType ()

Also: SpringBeans

Return the desired service type.

public void setBeanClassLoader (ClassLoader beanClassLoader)

Also: SpringBeans

Callback that supplies the bean class loader to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean's afterPropertiesSet() method or a custom init-method.

Parameters

beanClassLoader	the owning class loader; may be `null` in which case a default `ClassLoader` must be used, for example the `ClassLoader` obtained via `getDefaultClassLoader()`

public void setServiceType (Class serviceType)

Also: SpringBeans

Specify the desired service type (typically the service's public API).

Protected Methods

protected Object createInstance ()

Also: SpringBeans

Delegates to getObjectToExpose(java.util.ServiceLoader).

Returns

the object to expose

protected abstract Object getObjectToExpose (ServiceLoader serviceLoader)

Also: SpringBeans

Determine the actual object to expose for the given ServiceLoader.

Left to concrete subclasses.

Parameters

serviceLoader	the ServiceLoader for the configured service class

Returns

the object to expose
