Detailed Description

The base class for file-output-focused implementations of the DataStore interface

To create such an implementation, perform the following steps:

1) Create a class which satisfies the constraints expressed in the FileHandleConcept below - this package's SummaryTextDataWriter is an example

2) Declare a data store plugin which public-ally derives from FileDataStoreImpl, where FileDataStoreImpl has been parametrized with the class described in (1). In this package, SummaryTextDataStore is an example.

3) Implement the pure virtual open_new_file function, where the main purpose of the implementation should be to reset the FileDataStoreImpl's unique pointer data member to a new instance of the class in (1)

4) In the (likely) event that the open_new_file implementation needs configurable parameters which aren't already available in appmodel::DataStoreConf, create an OKS schema class which derives from appmodel::DataStoreConf as a superclass and adds parameters as needed. See DataStoreConfTestDeriv in this package, and how it's used by SummaryTextDataStore
