Class Container2ApplicationContext

java.lang.Object
  jfun.yan.spring.Container2ApplicationContext

All Implemented Interfaces:

org.springframework.beans.factory.BeanFactory, org.springframework.beans.factory.HierarchicalBeanFactory, org.springframework.beans.factory.ListableBeanFactory, org.springframework.context.ApplicationContext, org.springframework.context.ApplicationEventPublisher, org.springframework.context.MessageSource, org.springframework.core.io.ResourceLoader, org.springframework.core.io.support.ResourcePatternResolver

public class Container2ApplicationContext
extends java.lang.Object
implements org.springframework.beans.factory.ListableBeanFactory, org.springframework.context.ApplicationContext

This class adapts a yan Container object to Spring's ApplicationContext (primarily ListableBeanFactory) interface.

Many Thanks to spring for making ApplicationContext an interface! It helped.

Get the number of components registered under a string key.

Specified by:

getBeanDefinitionCount in interface org.springframework.beans.factory.ListableBeanFactory

getBeanDefinitionNames

public java.lang.String[] getBeanDefinitionNames()

Get all the component keys that are of String type.

retrieves the string keys of all components whose's static instance type is a subtype of the required type.

FactoryBean's are not instantiated.

Specified by:

Parameters:

type - the type to match. Null indicates all.

Returns:

the keys.

getBeanNamesForType

retrieves the string keys of all components whose's static instance type is a subtype of the required type.

FactoryBean's are instantiated if necessary to find out the product type.

Parameters:

Returns:

the keys.

getBeanNamesForType

public java.lang.String[] getBeanNamesForType(java.lang.Class type,
                                              boolean includePrototypes,
                                              boolean includeFactoryBeans)

containsBeanDefinition

public boolean containsBeanDefinition(java.lang.String beanName)

Specified by:

getBeansOfType

public java.util.Map getBeansOfType(java.lang.Class type)
                             throws org.springframework.beans.BeansException

Get the (String,Object) map of all components with the given type.

Specified by:

getBeansOfType in interface org.springframework.beans.factory.ListableBeanFactory

Parameters:

type - the expected type. If this type is FactoryBean, the component is adapted to FactoryBean without actually instantiating instance.

Returns:

the Map object containing component instances (if the type is not BeanFactory), otherwise BeanFactory objects.

Throws:

org.springframework.beans.BeansException

getBeansOfType

public java.util.Map getBeansOfType(java.lang.Class type,
                                    boolean includePrototypes,
                                    boolean includeFactoryBeans)
                             throws org.springframework.beans.BeansException

Get the (String,Object) map of all components with the given type.

Specified by:

getBeansOfType in interface org.springframework.beans.factory.ListableBeanFactory

Parameters:

type - the expected type.

includePrototypes - Are the components who may not be singletons included?

includeFactoryBeans - Are FactoryBean objects included?

Returns:

the Map object containing component instances.

Throws:

org.springframework.beans.BeansException

getBean

public java.lang.Object getBean(java.lang.String name)
                         throws org.springframework.beans.BeansException

Get a bean object.

Specified by:

getBean in interface org.springframework.beans.factory.BeanFactory

Parameters:

name - the name of the component. If the name starts with a "&", as specified by Spring, a FactoryBean object is returned corresponding to the component, otherwise the component itself is instantiated.

Throws:

org.springframework.beans.BeansException

getBean

public java.lang.Object getBean(java.lang.String beanname,
                                java.lang.Class requiredType)
                         throws org.springframework.beans.BeansException

Get a bean object.

Specified by:

getBean in interface org.springframework.beans.factory.BeanFactory

Parameters:

beanname - the name of the component. If the name starts with a "&", as specified by Spring, a FactoryBean object is returned corresponding to the component, otherwise the component itself is instantiated.

requiredType - the expecting type. If the name starts with a "&", as specified by Spring convention, the type has to be either null or FactoryBean or a super type of FactoryBean. And in that case, a FactoryBean object is returned. If the name is a regular bean name, the corresponding component is instantiated.

Throws:

org.springframework.beans.BeansException

containsBean

Same as containsBeanDefinition(String) since this class does not care about hierarchy. In fact, Yan does not create Spring hierarchies.

Specified by:

containsBean in interface org.springframework.beans.factory.BeanFactory

isSingleton

public boolean isSingleton(java.lang.String name)
                    throws org.springframework.beans.factory.NoSuchBeanDefinitionException

Specified by:

isSingleton in interface org.springframework.beans.factory.BeanFactory

Throws:

org.springframework.beans.factory.NoSuchBeanDefinitionException

getType

public java.lang.Class getType(java.lang.String name)
                        throws org.springframework.beans.factory.NoSuchBeanDefinitionException

Get the static type of a component identified by the name.
