public class OmeroContext
extends ClassPathXmlApplicationContext

Provides static access for the creation of singleton and non-singleton application contexts. Also provides context names as constant fields which can be used for the lookup of particular contexts, through either getInstance(String) or ServiceFactory.ServiceFactory(String). By passing a Properties instance into the getClientContext(Properties) method, a non-static version is created. Currently this is only supported for the client context.

Since:

OME3.0

Method Detail

getClientContext

public static OmeroContext getClientContext()

create (if necessary) and return the single default client OmeroContext. Any two calls to this method will return the same (==) context instance.

See Also:

CLIENT_CONTEXT

getClientContext

public static OmeroContext getClientContext(Properties props)

initialize a new client OmeroContext (named CLIENT_CONTEXT), using the getContext(Properties, String) method.

See Also:

getContext(Properties, String), CLIENT_CONTEXT, ServiceFactory.ServiceFactory(Login), ServiceFactory.ServiceFactory(Server), ServiceFactory.ServiceFactory(Properties)

getContext

public static OmeroContext getContext(Properties props,
                                      String context)

initialize a new client OmeroContext using the Properties provided as values for property (e.g. ${name}) replacement in Spring. Two calls to this method with the same argument will return different ( =! ) contexts.

Parameters:

props - Non-null properties for replacement.

context - Non-null name of context to find in beanRefContext.xml

See Also:

ServiceFactory.ServiceFactory(Login), ServiceFactory.ServiceFactory(Server), ServiceFactory.ServiceFactory(Properties)

getManagedServerContext

public static OmeroContext getManagedServerContext()

create (if necessary) and return the single default managed OmeroContext. Any two calls to this method will return the same (==) context instance. Managed means that the services are fully wrapped by interceptors, and are essentially the services made available remotely.

See Also:

MANAGED_CONTEXT

getInstance

public static OmeroContext getInstance(String beanFactoryName)

create (if necessary) and return the single default OmeroContext named by the beanFactoryName parameter. Any two calls to this method with the same parameter will return the same (==) context instance.

See Also:

getClientContext(), getManagedServerContext()

applyBeanPropertyValues

public void applyBeanPropertyValues(Object target,
                                    String beanName)

Uses the methods of this context's BeanFactory to autowire any Object based on the given beanName.

See Also:

AutowireCapableBeanFactory.applyBeanPropertyValues(java.lang.Object, java.lang.String)

applyBeanPropertyValues

public void applyBeanPropertyValues(Object target,
                                    Class<? extends ServiceInterface> beanInterface)

Uses the methods of this context's BeanFactory to autowire any Object based on the service class. This is used by SelfConfigurableService instances to acquire dependencies.

See Also:

SelfConfigurableService, AutowireCapableBeanFactory.applyBeanPropertyValues(java.lang.Object, java.lang.String)

refreshAll

public void refreshAll()

refreshes all the nested OmeroContexts within this instance. This is useful when using a static context, and Properties which were pulled from System.getProperties() have been changed. If this is a server-side instance (MANAGED_CONTEXT), this may take a significant amount of time.

See Also:

ConfigurableApplicationContext.refresh()

refreshAllIfNecessary

public void refreshAllIfNecessary()

Calls refreshAll() if AbstractApplicationContext.isRunning() throws an IllegalStateException.

closeAll

public void closeAll()

closes all the nested OmeroContexts within this instance. If this is a server-side instance (MANAGED_CONTEXT), this may take a significant amount of time.

See Also:

ConfigurableApplicationContext.close()

getProperty

public String getProperty(String propertyName)

publishEvent

public void publishEvent(ApplicationEvent event)

Specified by:

publishEvent in interface ApplicationEventPublisher

Overrides:

publishEvent in class AbstractApplicationContext

publishMessage

public void publishMessage(InternalMessage msg)
                    throws Throwable

Convenience method around publishEvent(org.springframework.context.ApplicationEvent) which catches all MessageException and unwraps the contained Throwable instance and rethrows.

Parameters:

msg -

Throws:

Throwable

onRefresh

protected void onRefresh()
                  throws BeansException

Overrides:

onRefresh in class AbstractApplicationContext

Throws:

BeansException
