Maybe if we go for example or more details information that could help.
Here is my situation :
I have an *InfrastructureService*, which require a *KnowledgeBaseService* which
in turn require an*ConFigDataObject*. My configDataObject contains
information coming from the inputs of the program.*The configDataObject
store these information after doing some validation and processing on those
inputs*. For instance a string representing file path can be provided to
it, and it will validate that it is a file that exist, and provide a getter
method that return that File to its consumer (i.e instead of the fileName).
Other things might be URLNname to real URL Object, and so on.
The important point here is this following graph: *InfrastructureService*
-> *KnowledgeBaseService* ->*ConFigDataObject* -> *InputData*
Therefore the *InfrastructureService* can only work with a
*knowledgeBaseService* that is started with the right inputFile, URL,
workingfolder and etc.... which is provided to it with a configDataObject,
that receive them from the input of the program and store a processed
version of them.
Therefore as of now what i do is to have a assistedFactory to create the
*knowledgeBaseService*. It takes as parameter the ConfigDataObject. The
*configDataObject* is created with a *factoryMethod (Scala Companion
Object)*. Finally, the an assistedFactory is also create for the
*InfrastructureService*which takes as parameter for its *creation method* a
*KnowledgeBaseService*.
So what exactly are you recommending here ? Would suggest to:
val data = new ConfigData(.....)
Class module extends AbstractModule {
bind(Configdata).toInstance(data)
.....
}
I have to try.... but let me know if i got u right please
