Constructor Detail

MarcDirStreamReader

public MarcDirStreamReader(String dirName)

Constructs an instance that traverses the directory specified in the parameter.

Parameters:

dirName - - The path of the directory from which to read all of the .mrc files

MarcDirStreamReader

public MarcDirStreamReader(File dir)

Constructs an instance that traverses the directory specified in the parameter.

Parameters:

dir - - The path of the directory from which to read all of the .mrc files

MarcDirStreamReader

public MarcDirStreamReader(String dirName,
                   boolean permissive,
                   boolean convertToUTF8)

Constructs an instance that traverses the directory specified in the parameter. Takes the values passed in for permissive and convertToUTF8 and passes them on to each of the MarcPermissiveStreamReader that it creates.

Parameters:

dirName - - The path of the directory from which to read all of the .mrc files

permissive - - Set to true to specify that reader should try to handle and recover from errors in the input.

convertToUTF8 - - Set to true to specify that reader should convert the records being read to UTF-8 encoding as they are being read.
