Method Detail

findByMIMEType

public BitstreamFormat findByMIMEType(Context context,
                                      String mimeType,
                                      boolean includeInternal)
                               throws SQLException

Find a bitstream format by its (unique) MIME type. If more than one bitstream format has the same MIME type, the one returned is unpredictable.

Specified by:

findByMIMEType in interface BitstreamFormatDAO

Parameters:

context - DSpace context object

mimeType - MIME type value

includeInternal - whether to include internal mimetypes

Returns:

the corresponding bitstream format, or null if there's no bitstream format with the given MIMEtype.

Throws:

SQLException - if database error

findByShortDescription

public BitstreamFormat findByShortDescription(Context context,
                                              String desc)
                                       throws SQLException

Find a bitstream format by its (unique) short description

Specified by:

findByShortDescription in interface BitstreamFormatDAO

Parameters:

context - DSpace context object

desc - the short description

Returns:

the corresponding bitstream format, or null if there's no bitstream format with the given short description

Throws:

SQLException - if database error

updateRemovedBitstreamFormat
