ParseContextClass in Java

ParseContext class is a component of the Java package org.apache.tika.parser, which is used to parse context and pass it on to the Tika  (The Apache Tika toolkit detects and extracts metadata and text from over a thousand different file types) parsers org.apache.tika.parser.ParseContext implements a Serializable interface.

public class ParseContext extends Object implements Serializable

Constructor:

1. ParseContext() – ParseContext() initialize a new instance of ParseContext class.

ParseContext p = new ParseContext()

Note: p is the new instance of ParseContext class.

9.	set(Class<T> key, T value)	set(Class<T> key, T value)  adds the given value to the context to implement the given interface.	<T> void

Example:

Java

// Java Program To Get Content of the
// document using Tika Toolkit and
// ContextParser:
import java.io.*;

// importing File class
import java.io.File.*;
import org.apache.tika.exception.TikaException;
import org.apache.tika.metadata.Metadata;
import org.apache.tika.parser.ParseContext;
import org.apache.tika.parser.txt.TXTParser;
import org.apache.tika.sax.BodyContentHandler;
// import the necessary Tika packages
import org.xml.sax.SAXException;

class GFG {
    public static void main(String[] args)
    {
        // new instance of FIle is created
        File fileName = new File("tmp.txt");

        // new instance of FileInputStream is created for
        // reading purpose
        FileInputStream fileInputStream
            = new FileInputStream(fileName);

        // new instance of parseContext class is created
        ParseContext parseContext = new ParseContext();

        // new instance of MetaData is created
        MetaData metaData = new MetaData();

        // new instance of TXTParser is created for plain
        // text parsing purpose
        TXTParser textParser = new TXTParser();

        // new instance of BodyContentHandler is created
        BodyContentHandler bodyContentHandler
            = new BodyContentHandler();

        // TXTParser parse method is called for parsing a
        // document stream into sequence of XHTML SAX events.
        textParser.parse(fileInputStream,
                         bodyContentHandler, metaData,
                         parseContext);

        System.out.println("Contents of the document:"
                           + bodyContenthandler.toString());
    }
}

Output-

Contents of the document:GFG is the best website for programmer

Note – The tmp.txt file contains the following data.
