Package org.apache.tika.detect.zip

Class GeoGebraDetector

java.lang.Object

org.apache.tika.detect.zip.GeoGebraDetector

All Implemented Interfaces:

Serializable, ZipContainerDetector

public class GeoGebraDetector
extends Object
implements ZipContainerDetector

Detects the zip-based GeoGebra formats by their well-known entry names:

• geogebra.xml at the root → a worksheet (*.ggb)
• structure.json at the root plus at least one _slide<N>/geogebra.xml → GeoGebra Notes/Slides (*.ggs)
• geogebra_macro.xml at the root → a tool (*.ggt)

A worksheet with macros contains both geogebra.xml and geogebra_macro.xml, so the worksheet check takes precedence over the tool check, and the decision is only made once all entry names have been seen.
