Method Detail

readBibliographyFile

public ItemDataProvider readBibliographyFile(File bibfile)
                                      throws FileNotFoundException,
                                             IOException

Reads all items from an input bibliography file and returns a provider serving these items

Parameters:

bibfile - the input file

Returns:

the provider

Throws:

FileNotFoundException - if the input file was not found

IOException - if the input file could not be read

readBibliographyFile

public ItemDataProvider readBibliographyFile(InputStream bibstream,
                                             String filename)
                                      throws IOException

Reads all items from an input stream and returns a provider serving these items. Note that you can supply an additional file name to help the method to determine the exact bibliography file format. If you don't know the file name you can pass null, but in this case the method's result might try to read the input stream using the wrong file format (depending on the input stream's contents). Also note that the caller is responsible for closing the given input stream.

Parameters:

bibstream - the input stream

filename - the name of the input file (can be null if you don't know the name)

Returns:

the provider

Throws:

IOException - if the input stream could not be read

readBibliographyFile

public ItemDataProvider readBibliographyFile(InputStream bibstream,
                                             BibliographyFileReader.FileFormat format)
                                      throws IOException

Reads all items from an input stream using the given file format and returns a provider serving these items.

Parameters:

bibstream - the input stream

format - the bibliography file format

Returns:

the provider

Throws:

IOException - if the input stream could not be read

determineFileFormat

public BibliographyFileReader.FileFormat determineFileFormat(File bibfile)
                                                      throws FileNotFoundException,
                                                             IOException

Reads the first 100 KB of the given bibliography file and tries to determine the file format

Parameters:

bibfile - the input file

Returns:

the file format (or BibliographyFileReader.FileFormat.UNKNOWN if the format could not be determined)

Throws:

FileNotFoundException - if the input file was not found

IOException - if the input file could not be read

determineFileFormat

public BibliographyFileReader.FileFormat determineFileFormat(BufferedInputStream bis,
                                                             String filename)
                                                      throws IOException

Reads the first bytes of the given input stream and tries to determine the file format. Resets the input stream to the position it had when the method was called. Reads up to 100 KB and before giving up. Note that you can supply an additional file name to help the method to determine the exact file format. If you don't know the file name you can pass null, but in this case the method's result might be wrong (depending on the input stream's contents).

Parameters:

bis - a buffered input stream that supports the mark and reset methods

filename - the name of the input file (can be null if you don't know the name)

Returns:

the file format (or BibliographyFileReader.FileFormat.UNKNOWN if the format could not be determined)

Throws:

IOException - if the input stream could not be read
