问题
With SubCut I can define a BindingModule and use modifyBindings to get a new one which can overwrite some bindings and also add new bindings. Is there a utility where instead of saying
val module : BindingModule
val newModule = module.modifBindings(...)
I could instead do something like
val mergedModule = merge(module1,module2,module3,...)
The reason is I am writing an application with "pluggable" jars - each such jar will have a META-INF/bindings.properties file which will expose the class name of its BindingModule. My main entry jar will instantiate those BindingModules via reflection and then combine them.
The idea being that if the pluggable jars follow the convention of providing META-INF/bindings.properties then there is no new configuration needed to deploy the application.
回答1:
Yes, just use the ~ operator, as shown in this test case from the SubCut project.
For the case of interdependent modules, please expand your question with more details on how you implemented that.
