Modifier and Type	Method and Description
public void	afterPropertiesSet() Implements org.springframework.beans.factory.InitializingBean.afterPropertiesSet. Invoked by the containing `BeanFactory` after it has set all bean properties and satisfied `BeanFactoryAware`, `ApplicationContextAware` etc. This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
public ConcurrentMapCache	getObject() Implements org.springframework.beans.factory.FactoryBean.getObject. Return an instance (possibly shared or independent) of the object managed by this factory.
public Class<?>	getObjectType() Implements org.springframework.beans.factory.FactoryBean.getObjectType. Return the type of object that this FactoryBean creates, or `null` if not known in advance.
public boolean	isSingleton() Overrides default org.springframework.beans.factory.FactoryBean.isSingleton. Is the object managed by this factory a singleton?
public void	setAllowNullValues(boolean allowNullValues) Set whether to allow `null` values (adapting them to an internal null holder value).
public void	setBeanName(String the name of the bean in the factory. Note that this name is the actual bean name used in the factory, which may differ from the originally specified name: in particular for inner bean names, the actual bean name might have been made unique through appending "#..." suffixes. Use the `BeanFactoryUtils#originalBeanName(String)` method to extract the original bean name (without suffix), if desired. beanName) Implements org.springframework.beans.factory.BeanNameAware.setBeanName. Set the name of the bean in the bean factory that created this bean.
public void	setName(String name) Specify the name of the cache.
public void	setStore(ConcurrentMap<Object, Object> store) Specify the ConcurrentMap to use as an internal store (possibly pre-populated).

getObject	back to summary
public ConcurrentMapCache getObject() Implements org.springframework.beans.factory.FactoryBean.getObject. Doc from org.springframework.beans.factory.FactoryBean.getObject. Return an instance (possibly shared or independent) of the object managed by this factory. As with a `BeanFactory`, this allows support for both the Singleton and Prototype design pattern. If this FactoryBean is not fully initialized yet at the time of the call (for example because it is involved in a circular reference), throw a corresponding `FactoryBeanNotInitializedException`. As of Spring 2.0, FactoryBeans are allowed to return `null` objects. The factory will consider this as normal value to be used; it will not throw a FactoryBeanNotInitializedException in this case anymore. FactoryBean implementations are encouraged to throw FactoryBeanNotInitializedException themselves now, as appropriate. Returns:ConcurrentMapCache an instance of the bean (can be `null`) Annotations @Override @Nullable

getObjectType	back to summary
public Class<?> getObjectType() Implements org.springframework.beans.factory.FactoryBean.getObjectType. Doc from org.springframework.beans.factory.FactoryBean.getObjectType. Return the type of object that this FactoryBean creates, or `null` if not known in advance. This allows one to check for specific types of beans without instantiating objects, for example on autowiring. In the case of implementations that are creating a singleton object, this method should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too. This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available. Note Autowiring will simply ignore FactoryBeans that return `null` here. Therefore, it is highly recommended to implement this method properly, using the current state of the FactoryBean. Returns:Class<?> the type of object that this FactoryBean creates, or `null` if not known at the time of the call Annotations @Override

isSingleton back to summary

isSingleton	back to summary
public boolean isSingleton() Overrides default org.springframework.beans.factory.FactoryBean.isSingleton. Doc from org.springframework.beans.factory.FactoryBean.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. Hence, do not return `true` unless the FactoryBean always exposes the same reference. The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there. Note This method returning `false` does not necessarily indicate that returned objects are independent instances. An implementation of the extended `SmartFactoryBean` interface may explicitly indicate independent instances through its `SmartFactoryBean#isPrototype()` method. Plain `FactoryBean` implementations which do not implement this extended interface are simply assumed to always return independent instances if the `isSingleton()` implementation returns `false`. The default implementation returns `true`, since a `FactoryBean` typically manages a singleton instance. Returns:boolean whether the exposed object is a singleton Annotations @Override

public void setBeanName(String beanName) Implements org.springframework.beans.factory.BeanNameAware.setBeanName. Doc from org.springframework.beans.factory.BeanNameAware.setBeanName. Set the name of the bean in the bean factory that created this bean.
