public java.lang.String identify(java.io.InputStream dataStream,
                        java.lang.String extension)
                          throws MimeTypeParseException

Specified by:

identify in interface MimeTypeIdentifier

Parameters:

dataStream - an InputStream containing the data

extension - the extension of the filename

Returns:

the detected MimeType

Throws:

MimeTypeParseException - if any error occurs
