Great stuff Jim, these changes look really good to me. Makes implementing a binding way easier.
What do you think about having an abstract SPI class for the TargetInvoker which includes all the cachable, optimizable and invoke methods? ...ant On 8/10/06, Jim Marino <[EMAIL PROTECTED]> wrote:
I've checked in an example of a simple binding (r430211) that demonstrates creating services and references. For references, the binding just echoes a single param back to the client. Related to this, I've also completed a series of commits that move application wiring from the responsibility of the builders to initiate up into the builder registry which delegates to the system wire service. Once a Service, Reference, or Component is created and returned from a builder, the builder registry will invoke the wire service to create the appropriate inbound and outbound wires. These wires will then be injected into the Service, Reference or Component. At a later point, the connector will bridge outbound (source) to inbound (target) wires. Services and References will generally not need to do anything other than hold onto the wires (implemented as a convenience by the extension base classes), but components are responsible for implementing a strategy for injecting them onto implementation instances as the latter are requested. In the case of Java, this involves delegating back to the wire service to create a proxy fronting the wire and implementing the appropriate reference interface. This proxy will be injected onto an implementation instance as it is created. BPEL or an other implementation type may do something entirely different and maybe not even use proxies. Certain types of composite components may need to manually bridge Services to targets. For example, a Spring composite is opaque to the SCA wiring fabric in that its beans are not visible as components. The Spring builder is responsible for delegating to the builder registry to create a service which it then must provide with a target invoker capable of dispatching into the Spring application context and to a target bean. This can be viewed as the SCA wiring mechanism delegating to Spring for internal wiring.
