Method Detail

detectFileEncoding

public Charset detectFileEncoding(File file)

detectFileEncoding

public Charset detectFileEncoding(File file,
                                  FileParametersDetector detector)

Tries to predict encoding of a file.

Parameters:

file - a file for prediction

detector - an implementation of FileParametersDetector class. If null, it'll use DefaultFileParametersDetector

Returns:

Charset class is the corresponding encoding of the file. If the detector cannot define an encoding, then it returns the system default encoding.

detectFileMimeType

public String detectFileMimeType(File file)

Tries to predict MIME type of file.

detectFileMimeType(File, FileParametersDetector)

detectFileMimeType

public String detectFileMimeType(File file,
                                 FileParametersDetector detector)

Tries to predict MIME type of file.

Parameters:

file - a file for prediction

detector - an implementation of FileParametersDetector class. If null, it'll use DefaultFileParametersDetector

Returns:

MIME type of file. If the detector cannot define the MIME type, then it returns the default value (ProtocolUtils.DEFAULT_BINARY_CONTENT_TYPE)
