Detailed Description

Class to declare a service implementation.

There is no need to implement lang::XServiceInfo nor lang::XInitialization anymore. The declaration can be done in various ways, the (simplest) form is

class MyClass : public cppu::WeakImplHelper<XInterface1, XInterface2> {
public:
    MyClass( uno::Reference<uno::XComponentContext> const& xContext )
    [...]
};
[...]
namespace sdecl = comphelper::service_decl;
sdecl::ServiceDecl const myDecl(
    sdecl::class_<MyClass>(),
    "my.unique.implementation.name",
    "MyServiceSpec1;MyServiceSpec2" );

If the service demands initialization by arguments, the implementation class has to define a constructor taking both arguments and component context:

class MyClass : public cppu::WeakImplHelper<XInterface1, XInterface2> {
public:
    MyClass( uno::Sequence<uno::Any> const& args,
             uno::Reference<uno:XComponentContext> const& xContext )
    [...]
};
[...]
namespace sdecl = comphelper::service_decl;
sdecl::ServiceDecl const myDecl(
    sdecl::class_<MyClass, sdecl::with_args<true> >(),
    "my.unique.implementation.name",
    "MyServiceSpec1;MyServiceSpec2" );

Additionally, there is the possibility to process some code after creation, e.g. to add the newly created object as a listener or perform aggregation (C++-UNO only):

uno::Reference<uno::XInterface> somePostProcCode( MyClass * p );
[...]
namespace sdecl = comphelper::service_decl;
sdecl::ServiceDecl const myDecl(
    sdecl::class_<MyClass, ... >(&somePostProcCode),
    "my.unique.implementation.name",
    "MyServiceSpec1;MyServiceSpec2" );

In the latter case, somePostProcCode gets the yet unacquired "raw" pointer.
