Overview

A library to identify file formats and to extract meta-data from those files.

Features

• recognize common formats based on an XML-based matching description
• extract meta-data from certain formats using specialized matchers and extractors
• allow adding new recognized formats

Usage

Maven dependency

<dependency>
    <groupId>org.jadice.filetype</groupId>
    <artifactId>analyzer</artifactId>
    <version>2.3.0</version>
</dependency>

Minimal usage

Map<String, Object> results =
    Analyzer.getInstance("/magic.xml")
        .analyze(new File("my-example-file.pdf"));

System.out.println("Extension: " + results.get(ExtensionAction.KEY));
System.out.println("Mime-Type: " + results.get(MimeTypeAction.KEY));

// some types have specialized matchers providing extra info
System.out.println("Details: " + results.get(PDFMatcher.DETAILS_KEY));
