Package opennlp.tools.sentdetect

# Class DefaultSDContextGenerator

java.lang.Object
opennlp.tools.sentdetect.DefaultSDContextGenerator

All Implemented Interfaces:
  `opennlp.tools.sentdetect.SDContextGenerator`

Direct Known Subclasses:
  `SentenceContextGenerator`

public class DefaultSDContextGenerator extends Object implements opennlp.tools.sentdetect.SDContextGenerator
Generate event contexts for maxent decisions for sentence detection.

Features reflect `StringUtil.isWhitespace(char)`, whose result depends on the active `WhitespaceMode`; they are part of every trained sentence detector model, so training and decoding must use the same `WhitespaceMode`.
