org.apache.geode.Instantiator

org.springframework.data.gemfire.serialization.WiringInstantiator

All Implemented Interfaces:

Aware, BeanFactoryAware, DisposableBean, InitializingBean

public class WiringInstantiator
extends Instantiator
implements BeanFactoryAware, InitializingBean, DisposableBean

Apache Geode Instantiator that performs instance wiring using the Spring IoC container, allowing common properties to be injected before the object is hydrated/deserialized. The newly created instances can be configured either by relying on an existing bean definition (which acts as a template) or by providing an embedded configuration through annotations. Can reuse existing Instantiators to optimize instance creation. If one is not provided, it will fallback to reflection invocation. By default, on initialization, the class will register itself as an Instantiator through Instantiator.register(Instantiator). This behaviour can be disabled through setAutoRegister(boolean). Additionally, the instantiator registration is not distributed by default, to allow the application context to be reused. This can be changed through setDistribute(boolean).

Method Details

afterPropertiesSet

public void afterPropertiesSet()

Specified by:

afterPropertiesSet in interface InitializingBean

destroy

public void destroy()
             throws Exception

Specified by:

destroy in interface DisposableBean

Throws:

Exception

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)
                    throws BeansException

Specified by:

setBeanFactory in interface BeanFactoryAware

Throws:

BeansException

newInstance

public DataSerializable newInstance()

Specified by:

newInstance in class Instantiator

setConfigurer

public void setConfigurer(BeanConfigurerSupport configurer)

Sets the manager responsible for configuring the newly created instances. The given configurer needs to be configured and initialized before-hand.

Parameters:

configurer - the configurer to set

setAutoRegister

public void setAutoRegister(boolean autoRegister)

Sets the auto-registration of this Instantiator during the container startup. Default is true, meaning the registration will occur once this factory is initialized.

Parameters:

autoRegister - the autoRegister to set

See Also:

• Instantiator.register(Instantiator)

setDistribute

public void setDistribute(boolean distribute)

Sets the distribution of the region of this Instantiator during the container startup. Default is false, meaning the registration will not be distributed to other clients.

Parameters:

distribute - whether the registration is distributable or not
