Interface MimeTypeDetector

All Known Implementing Classes:

ContentDetector, NameOnlyDetector, NullMimeTypeDetector, TikaMimeTypeDetector

public interface MimeTypeDetector

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

Method Summary

Modifier and Type	Method and Description
String	mimeTypeOf(String name, Binary binaryValue) Returns the MIME-type of a binary value, using its supplied content and/or its supplied name, depending upon the implementation.

Method Detail

mimeTypeOf

String mimeTypeOf(String name,
                  Binary binaryValue)
           throws RepositoryException,
                  IOException

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.

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:

IOException - If an error occurs reading the supplied content.

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