| Interface | Description |
|---|---|
| AppServiceHub |
A
annotationclass CordaService annotated class requires a constructor taking a
single parameter of type interface AppServiceHub.
With the interface AppServiceHub parameter a annotationclass CordaService is able to access to privileged operations.
In particular such a annotationclass CordaService can initiate and track flows marked
with annotationclass StartableByService. |
| ServiceHub |
A service hub is the starting point for most operations you can do inside the node. You are provided with one
when a class annotated with
annotationclass CordaService is constructed, and you have access to one inside flows. Most RPCs
simply forward to the services found here after some access checking. |
| ServicesForResolution |
Subset of node services that are used for loading transactions from the wire into fully resolved, looked up
forms ready for verification.
