All Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`protected Object`	`createInstance()`	Delegates to `getObjectToExpose(java.util.ServiceLoader)`.
`protected abstract Object`	`getObjectToExpose(ServiceLoader<?> serviceLoader)`	Determine the actual object to expose for the given ServiceLoader.
`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).

    Description copied from interface: BeanClassLoaderAware
    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'sInitializingBean.afterPropertiesSet() method or a custom init-method.
    Specified by:
    setBeanClassLoader in interface BeanClassLoaderAware
    Overrides:
    setBeanClassLoader in class AbstractFactoryBean<Object>
    Parameters:
    beanClassLoader - the owning class loader; may be null in which case a default ClassLoader must be used, for example the ClassLoader obtained via ClassUtils.getDefaultClassLoader()
  - createInstance
```
protected Object createInstance()
```
    Delegates to getObjectToExpose(java.util.ServiceLoader).
    Specified by:
    createInstance in class AbstractFactoryBean<Object>
    Returns:
    the object to expose
    See Also:
    AbstractFactoryBean.getObject()
  - getObjectToExpose
```
protected abstract Object getObjectToExpose(ServiceLoader<?> serviceLoader)
```
    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
