Class WindowsRegistryMimeDetector

java.lang.Object
  eu.medsea.mimeutil.detector.MimeDetector
      eu.medsea.mimeutil.detector.WindowsRegistryMimeDetector

public class WindowsRegistryMimeDetector
extends MimeDetector

Get the content type for a file extension as stored in the Windows Registry The extensions are stored at "HKEY_CLASSES_ROOT"

This MimeDetector will only operate on Windows machines. On any other platform the methods throw a UnsupportedOperationException (These are swallowed by the MimeUtil class) Therefore, it is perfectly acceptable to register this MimeDetector with MimeUtil and it will only be used on a Windows Platform. On all other platforms it will just be ignored.

To register this MimeDetector use
MimeUtil.registerMimeDetector("eu.medsea.mimeutil.detector.WindowsRegistryMimeDetector");

The Collection returned from the getMimeTypesXXX(...) Methods with contain either a single MimeType or the collection will be empty.

This MimeDetector only performs file extension mapping, so the methods taking an InputStream and byte array throw UnsupportedOperationException

getDescription

public String getDescription()

Description copied from class: MimeDetector

Abstract method to be implement by concrete MimeDetector(s).

Specified by:

getDescription in class MimeDetector

Returns:

description of this MimeDetector

getMimeTypesFile

public Collection getMimeTypesFile(File file)
                            throws UnsupportedOperationException

Description copied from class: MimeDetector

Abstract method that must be implemented by concrete MimeDetector(s). This takes a file object and is called by the MimeUtil getMimeTypes(File file) method. If your MimeDetector does not handle file names then either throw an UnsupportedOperationException or return an empty collection.

Specified by:

getMimeTypesFile in class MimeDetector

Returns:

Collection of matched MimeType(s)

Throws:

UnsupportedOperationException

getMimeTypesFileName

public Collection getMimeTypesFileName(String fileName)
                                throws UnsupportedOperationException

Description copied from class: MimeDetector

Abstract method that must be implemented by concrete MimeDetector(s). This takes a file name and is called by the MimeUtil getMimeTypes(String fileName) getMimeTypes(File file) getMimeTypes(URL url) methods. If your MimeDetector does not handle file names then either throw an UnsupportedOperationException or return an empty collection.

Specified by:

getMimeTypesFileName in class MimeDetector

Returns:

Collection of matched MimeType(s)

Throws:

UnsupportedOperationException

getMimeTypesURL

public Collection getMimeTypesURL(URL url)
                           throws UnsupportedOperationException

Description copied from class: MimeDetector

Abstract method that must be implemented by concrete MimeDetector(s). This takes a URL object and is called by the MimeUtil getMimeTypes(URL url) method. If your MimeDetector does not handle file names then either throw an UnsupportedOperationException or return an empty collection.

Specified by:

getMimeTypesURL in class MimeDetector

Returns:

Collection of matched MimeType(s)

Throws:

UnsupportedOperationException
