Method Detail

mangleFilename

String mangleFilename(String filename,
                    String fieldname)

This is invoked by Codecs.mpFormDataDecode for each file found in the data, just before the file is created and written. If null is returned then the file is not created or written. This allows you to control which files are written and the names of the resulting files.

For Codecs.mpFormDataEncode this is also invoked on each filename, allowing you to control the actual name used in the filename attribute of the Content-Disposition header. This does not change the name of the file actually read. If null is returned then the file is ignored.

Parameters:

filename - the original filename in the Content-Disposition header

fieldname - the name of the this field, i.e. the value of the name attribute in Content-Disposition header

Returns:

the new file name, or null if the file is to be ignored.
