Class TextObject

java.lang.Object

com.optimaize.langdetect.text.TextObject

All Implemented Interfaces:

java.lang.Appendable, java.lang.CharSequence

@Beta
public class TextObject
extends java.lang.Object
implements java.lang.CharSequence, java.lang.Appendable

A convenient text object implementing CharSequence and Appendable. This is an ideal object to use for learning text to create LanguageProfiles, as well as to pass it in to LanguageDetector.detect(java.lang.CharSequence). To get one, use a TextObjectFactory (through a TextObjectFactoryBuilder). Example use: //create the factory once: TextObjectFactory textObjectFactory = new TextObjectFactoryBuilder() .withTextFilter(UrlTextFilter.getInstance()) .build(); //then create as many text objects as you like: TextObject inputText = textObjectFactory.create().append("deutsche Text").append(" ").append("blah blah"); All append() methods go through the textFilter. Equals/hashCode are not implemented as of now on purpose. You may want to call toString() and compare that.

Method Detail

append

public TextObject append(java.io.Reader reader)
                  throws java.io.IOException

Append the target text for language detection. This method read the text from specified input reader. If the total size of target text exceeds the limit size, the rest is ignored.

Parameters:

reader - the input reader (BufferedReader as usual)

Throws:

java.io.IOException - Can't read the reader.

append

public TextObject append(java.lang.CharSequence text)

Append the target text for language detection. If the total size of target text exceeds the limit size , the rest is cut down.

Specified by:

append in interface java.lang.Appendable

Parameters:

text - the target text to append
