opennlp.tools.util.FilterObjectStream<String,TokenSample>

opennlp.tools.tokenize.TokenSampleStream

All Implemented Interfaces:

AutoCloseable, ObjectStream<TokenSample>

public class TokenSampleStream
extends FilterObjectStream<String,TokenSample>

This class is a stream filter which reads in string encoded samples and creates TokenSamples out of them. The input string sample is tokenized if a whitespace or the special separator chars occur.

Sample:
"token1 token2 token3<SPLIT>token4"
The tokens token1 and token2 are separated by a whitespace, token3 and token3 are separated by the special character sequence, in this case the default split sequence.

The sequence must be unique in the input string and is not escaped.
