All Implemented Interfaces:

opennlp.maxent.EventStream

public class SDEventStream

extends java.lang.Object

implements opennlp.maxent.EventStream

An implementation of EventStream which assumes that it is receiving its data as one (valid) sentence per token. The default DataStream to use with this class is PlainTextByLineDataStream, but you can provide other types of DataStreams if you wish to receive data from sources other than plain text files; however, be sure that each token your DataStream returns is a valid sentence.
