Interface MimeTypeDetector

All Known Implementing Classes:
ApertureMimeTypeDetector, ExtensionBasedMimeTypeDetector, MimeTypeDetectors

@ThreadSafe
public interface MimeTypeDetector

MIME-type detection libraries must provide thread-safe implementations of this interface to enable DNA to use the libraries to return MIME-types for data sources.


Method Summary
 String mimeTypeOf(String name, InputStream content)
          Returns the MIME-type of a data source, using its supplied content and/or its supplied name, depending upon the implementation.
 

Method Detail

mimeTypeOf

String mimeTypeOf(String name,
                  InputStream content)
                  throws IOException
Returns the MIME-type of a data source, 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.

Note that detector implementations should not close the supplied input stream.

Parameters:
name - The name of the data source; may be null.
content - The content of the data source; may be null.
Returns:
The MIME-type of the data source, or optionally null if the MIME-type could not be determined.
Throws:
IOException - If an error occurs reading the supplied content.
