public abstract class AbstractModelClassFactory
extends Object
implements ModelClassFactory

Abstract base class for ModelClassFactory implementations that read event maps from the file system.

The directory can be set using setEventMapDirectory(String) and defaults to ca/uhn/hl7v2/parser/eventmap/. The file itself is a property file named after the HL7 version (e.g. 2.4.properties).
