Class DomainToModelMap

java.lang.Object
  opennlp.maxent.DomainToModelMap

public class DomainToModelMap
extends java.lang.Object

A class which stores a mapping from ModelDomain objects to MaxentModels. This permits an application to replace an old model for a domain with a newly trained one in a thread-safe manner. By calling the getModel() method, the application can create new instances of classes which use the relevant models.
