exportIteration

public static void exportIteration(org.openrdf.rio.RDFWriter writer,
                   org.openrdf.model.URI subject,
                   info.aduna.iteration.CloseableIteration<org.openrdf.model.Statement,org.openrdf.repository.RepositoryException> iteration)
                            throws org.openrdf.rio.RDFHandlerException,
                                   org.openrdf.repository.RepositoryException

LDP-Style to serialize a resource.

Parameters:

writer - the writer to serialize to

subject - the resource to serialize

iteration - the Iteration containing the data

Throws:

org.openrdf.rio.RDFHandlerException

org.openrdf.repository.RepositoryException

getAcceptPostHeader

public static String getAcceptPostHeader(String extraFormats)

matchDefaultMIMEType

public static <FF extends info.aduna.lang.FileFormat> FF matchDefaultMIMEType(String mimeType,
                                                              Iterable<FF> fileFormats)

Tries to match the specified MIME type with the MIME types of the supplied file formats. This method does exactly the same as FileFormat.matchMIMEType(String, Iterable) but only considers the default mimeTypes.

Parameters:

mimeType - A MIME type, e.g. "text/plain".

fileFormats - The file formats to match the MIME type against.

Returns:

A FileFormat object if the MIME type was recognized, or null otherwise.

matchDefaultMIMEType

public static <FF extends info.aduna.lang.FileFormat> FF matchDefaultMIMEType(String mimeType,
                                                              Iterable<FF> fileFormats,

Tries to match the specified MIME type with the default MIME types of the supplied file formats. The supplied fallback format will be returned when no matching format was found. This method does exactly the same as FileFormat.matchMIMEType(String, Iterable, info.aduna.lang.FileFormat) but only considers the default mimeTypes.

Parameters:

mimeType - A MIME type, e.g. "text/plain".

fileFormats - The file formats to match the MIME type against.

fallback - The file format to return if no matching format can be found.

Returns:

A FileFormat that matches the MIME type, or the fallback format if the extension was not recognized.
