Class TextDetector

java.lang.Object
  extended by org.apache.tika.detect.TextDetector
All Implemented Interfaces:
Detector

public class TextDetector
extends java.lang.Object
implements Detector

Content type detection of plain text documents. This detector looks at the beginning of the document input stream and considers the document to be a text document if no ASCII (ISO-Latin-1, UTF-8, etc.) control bytes are found.

Note that text documents with a character encoding like UTF-16 are better detected with MagicDetector and an appropriate magic byte pattern.

Since:
Apache Tika 0.3
