Examples of org.springframework.richclient.application.support.DefaultApplicationServices

org.springframework.richclient.application.support.DefaultApplicationServices
A default implementation of the ApplicationServices (service locator) interface. This implementation allows for the direct registration of service implementations by using various setter methods (like {@link #setImageSource(ImageSource)}). Service registry entries can also be added in bulk using the {@link #setRegistryEntries(Map)} method.
Except in testing environments, this class will typically be instantiated in the application context and the various service implementations will be set BY ID. The use of service bean ids instead of direct bean references is to avoid numerous problems with cyclic dependencies and other order dependent operations. So, a typical incarnation might look like this:
```
 <bean id="applicationServices" class="org.springframework.richclient.application.support.DefaultApplicationServices"> <property name="applicationObjectConfigurerId"><idref bean="applicationObjectConfigurer" /></property> <property name="imageSourceId"><idref bean="imageSource"/></property> <property name="rulesSourceId"><idref bean="rulesSource"/></property> <property name="conversionServiceId"><idref bean="conversionService"/></property> <property name="formComponentInterceptorFactoryId"><idref bean="formComponentInterceptorFactory"/></property> </bean> 
```
Note the use of the idref form instead of just using a string value. This is the preferred syntax in order to avoid having misspelled bean names go unreported.
Which service implementation is returned by {@link #getService(Class)} will be determined through the followingsteps:
1. Consult the current registry of service implementations which have been explicitly defined through bean definition. If a registry entry was made using a bean id, this is the point at which it will be dereferenced into the actual bean implementation. So, the bean impementation will not be referenced until it is requested.
2. If the service impl. is not found yet the short string name of the service' Java class in decapitalized JavaBeans property format will be used to lookup the service implementation in the current application context.
  If the service class is org.springframework.richclient.factory.MenuFactory the bean name menuFactory will be used to find the bean
3. If the service impl. is not found yet and a default implementation can be provided, it will be constructed at that time. Default implementations are provided for essentially all services referenced by the platform.
