All Implemented Interfaces:

FactoryBean

public class ResourceFactoryBean

extends java.lang.Object

Constructor Detail

ResourceFactoryBean

public ResourceFactoryBean()

Method Detail

setLocation

public void setLocation(Resource location)

Set the resource location.

Parameters:

location - the resource location to feed into getResource

getObject

public java.lang.Object getObject()

Description copied from interface: FactoryBean

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.

Specified by:

getObject in interface FactoryBean

Returns:

an instance of the bean (should never be null)

getObjectType

public java.lang.Class getObjectType()

Description copied from interface: FactoryBean

Return the type of object that this FactoryBean creates, or null if not known in advance. This allows to check for specific types of beans without instantiating objects, e.g. on autowiring.

For a singleton, this can simply return getObject().getClass(), or even null, as autowiring will always check the actual objects for singletons. For prototypes, returning a meaningful type here is highly advisable, as autowiring will simply ignore them else.

Specified by:

getObjectType in interface FactoryBean

Returns:

the type of object that this FactoryBean creates, or null

isSingleton

public boolean isSingleton()

Description copied from interface: FactoryBean

Is the bean managed by this factory a singleton or a prototype? That is, will getObject() always return the same object?

The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory.

Specified by:

isSingleton in interface FactoryBean

Returns:

if this bean is a singleton
