Method Detail

getBeanDefinitionCount

public int getBeanDefinitionCount()

Description copied from interface: ListableBeanFactory

Return the number of beans defined in the factory

Specified by:

getBeanDefinitionCount in interface ListableBeanFactory

See Also:

ListableBeanFactory.getBeanDefinitionCount()

getBeanDefinitionNames

public java.lang.String[] getBeanDefinitionNames()

Description copied from interface: ListableBeanFactory

Return the names of all beans defined in this factory

Specified by:

getBeanDefinitionNames in interface ListableBeanFactory

See Also:

ListableBeanFactory.getBeanDefinitionNames()

getBeanDefinitionNames

public java.lang.String[] getBeanDefinitionNames(java.lang.Class type)

Description copied from interface: ListableBeanFactory

Return the names of beans matching the given object type (including subclasses).

Specified by:

getBeanDefinitionNames in interface ListableBeanFactory

See Also:

ListableBeanFactory.getBeanDefinitionNames(Class)

getBean

public java.lang.Object getBean(java.lang.String name,
                                java.lang.Class requiredType)
                         throws BeansException

Description copied from interface: BeanFactory

Return an instance (possibly shared or independent) of the given bean name. Provides a measure of type safety by throwing an exception if the bean is not of the required type. This method allows a bean factory to be used as a replacement for the Singleton or Prototype design pattern.
Note that callers should retain references to returned objects. There is no guarantee that this method will be implemented to be efficient. For example, it may be synchronized, or may need to run an RDBMS query.

Specified by:

getBean in interface BeanFactory

BeanFactory.getBean(String, Class)

getBean

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

addBean

public void addBean(java.lang.String name,
                    java.lang.Object bean)

Add a new singleton bean

isSingleton

public boolean isSingleton(java.lang.String name)

Description copied from interface: BeanFactory

Is this bean a singleton? That is, will getBean() always return the same object?

Specified by:

isSingleton in interface BeanFactory

See Also:

BeanFactory.isSingleton(java.lang.String)

getAliases

public java.lang.String[] getAliases(java.lang.String name)

Description copied from interface: BeanFactory

Specified by:

getAliases in interface BeanFactory

Following copied from interface: com.interface21.beans.factory.BeanFactory

Parameters:

name - the bean name to check for aliases

Returns:

the aliases, or an empty array if none
