Class DefaultDetector

java.lang.Object

org.apache.tika.detect.CompositeDetector

org.apache.tika.detect.DefaultDetector

All Implemented Interfaces:

java.io.Serializable, Detector

public class DefaultDetector
extends CompositeDetector

A composite detector based on all the Detector implementations available through the service provider mechanism. Detectors are loaded and returned in a specified order, of user supplied followed by non-MimeType Tika, followed by the Tika MimeType class. If you need to control the order of the Detectors, you should instead construct your own CompositeDetector and pass in the list of Detectors in the required order.

Since:

Apache Tika 0.9

getDefaultDetectors

                                                            ServiceLoader loader)

Finds all statically loadable detectors and sort the list by name, rather than discovery order. Detectors are used in the given order, so put the Tika parsers last so that non-Tika (user supplied) parsers can take precedence.

Parameters:

loader - service loader

Returns:

ordered list of statically loadable detectors

getDetectors

public java.util.List<Detector> getDetectors()

Description copied from class: CompositeDetector

Returns the component detectors.

Overrides:
