Method Detail

values

public static WorkFiles[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (WorkFiles c : WorkFiles.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static WorkFiles valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getPreservationDir

protected static java.io.File getPreservationDir(Replica replica)

Get the base dir for all files related to bitpreservation for a given bitarchive.

Parameters:

replica - The name of a bitarchive.

Returns:

The directory to place bitpreservation for the archive under.

getSortedFile

protected static java.io.File getSortedFile(java.io.File unsortedFile)
                                     throws IOFailure

Get a sorted file from an unsorted one, updating if necessary.

Parameters:

unsortedFile - An unsorted file

Returns:

A file that contains the same lines as unsortedFile, but sorted. The file will be placed in the same directory as the input file, but have the name Constants.SORTED_OUTPUT_FILE defines.

Throws:

IOFailure - If the file does not exist.

write

public static void write(Replica replica,
                         WorkFiles fileType,
                         java.util.Set<java.lang.String> files)

Method for writing the list of files to a work file.

Parameters:

replica - The replica for the working file.

fileType - The type of working file.

files - The list of filenames (?) to write to the working file.

getFile

public static java.io.File getFile(Replica rep,
                                   WorkFiles fileType)

Method for retrieving a working file. Note: it is not tested, whether the file exists.

Parameters:

rep - The replica to whom the file corresponds.

fileType - The type of working file.

Returns:

The requested working file.

getLastUpdate

public static java.util.Date getLastUpdate(Replica rep,
                                           WorkFiles fileType)

Method for retrieving the last modified date of a working file for a specific replica. FIXME this might throw odd exceptions if the file does not exist.

Parameters:

rep - The replica for the working file.

fileType - The type of working file.

Returns:

The last modified date for the working file.

getLines

public static java.util.List<java.lang.String> getLines(Replica replica,
                                                        WorkFiles fileType)
