This package also contains edu.mayo.informatics.lexgrid.convert.directConversions.medDRA.MedDRAMapToLexGrid with a readMedDRAFile method that reads from a CSV file and persists it to objects defined in package edu.mayo.informatics.lexgrid.convert.directConversions.medDRA.Data.  While this data package defines some of the beans that model the content of lines read from the CSV file, it also organizes them into structures that are easier for the mapping code to useruse. The individual manner of implementation is left up to the developer but this is a good example of how a third party library was used to process the file and how the resulting objects were stored in a data structure that's easy for the mapping code to consume.

Once the source is read an persisted to the appropriate model objects the MedDRAMapToLexGrid class can map these data objects derived from the MedDRA source into a complete coding scheme object.

Pass Control Back to BaseLoader

So the tasks are to read the file into some kind of logical model or bean class object, organize these objects or make them available to be mapped into LexEVS objects, tie all objects together as a coding scheme, and pass this potentially large coding scheme object to the LexEVS BaseLoader to be persisted to the database.  Back up the execution chain in MeDRALoaderImpl the doLoad method first calls the mapping method of the conversion class MedDRA2LGMain to get the reading and mapping done, then passes control of the resulting coding scheme to BaseLoader by calling this.persistCodingSchemeToDatabase method on the BaseLoader super class.
