berry::IServiceLocator::GetService(Class)
. The implementation of AbstractServiceFactory
must be able to return a global service and multiple child services (if applicable).
Services must follow a general contract:
berry::IServiceLocator
.berry::IDisposable
.<!ELEMENT extension (serviceFactory? , sourceProvider?)+>
<!ATTLIST extension
point CDATA #REQUIRED
id CDATA #IMPLIED
name CDATA #IMPLIED>
Contribute services to the workbench.
<!ELEMENT serviceFactory (service+)>
<!ATTLIST serviceFactory
factoryClass CDATA #REQUIRED>
Match a service interface to a factory that can supply a hierachical implementation of that service.
AbstractServiceFactory
and can create the implementation for the serviceClass.<!ELEMENT service EMPTY>
<!ATTLIST service
serviceClass CDATA #IMPLIED>
A service this factory can provide.
<!ELEMENT sourceProvider (variable+)>
<!ATTLIST sourceProvider
provider CDATA #REQUIRED>
A Source Provider supplies source variables to the IEvaluationService. It can also notify the IEvaluationService when one or more of the variables change.
<!ELEMENT variable EMPTY>
<!ATTLIST variable
name CDATA #REQUIRED
priorityLevel (workbench|activeContexts|activeShell|activeWorkbenchWindow|activeEditorId|activePartId|activeSite) >
A source variable from this provider. A source provider must declare all variables that it provides.
ISources
for relative priority information.Here is a basic definition:
<extension point="org.blueberry.ui.services"> <serviceFactory factoryClass="my::LevelServiceFactory"> <service serviceClass="my::ILevelService"> </service> </serviceFactory> </extension>
The LevelServiceFactory
can return an ILevelService
when it is requested from the IServiceLocator
:
berry::ILevelService::Pointer s = GetSite()->GetService(my::ILevelService::GetStaticClassName());
std::cout << s->GetLevel();
In this test example, the factory would instantiate three ILevelService
implementations during the first call to GetSite()->GetService(*)
. The global one in the workbench, one for the workbench window, and one for the site.
