Description copied from interface: MimeTypeDetector

Returns the MIME-type of a binary value, using its supplied content and/or its supplied name, depending upon the implementation. If the MIME-type cannot be determined, either a "default" MIME-type or null may be returned, where the former will prevent earlier registered MIME-type detectors from being consulted.

Specified by:

mimeTypeOf in interface MimeTypeDetector

Parameters:

name - The name of the data source; may be null.

binaryValue - The value which contains the raw data for which the mime type should be returned; may be null.

Returns:

The MIME-type of the data source, or optionally null if the MIME-type could not be determined.

Throws:

RepositoryException - if any error occurs while attempting to read the stream from the binary value

IOException - If an error occurs reading the supplied content.
