Method Detail

copy

public static void copy(DataFile input,
                        DataFile output)
                 throws IOException

Copy a file, if input data is compressed, data will be uncompressed and if output require to be compressed output will be compressed.

Parameters:

input - input file

output - output file.

Throws:

IOException - if an error occurs while copying data

rawCopy

public static void rawCopy(DataFile input,
                           DataFile output)
                    throws IOException

Copy a file.

Parameters:

input - input file

output - output file.

Throws:

IOException - if an error occurs while copying data

symlinkOrCopy

public static void symlinkOrCopy(DataFile input,
                                 DataFile output)
                          throws IOException

Create a symbolic link if the input and output use the same protocol and if symbolic links are supported by the protocol. If symbolic link cannot be created, the input file will be copied.

Parameters:

input - input file

output - output file

Throws:

IOException - if an error occurs while copying data or creating the symbolic link

symlinkOrCopy

public static void symlinkOrCopy(DataFile input,
                                 DataFile output,
                                 boolean relativize)
                          throws IOException

Create a symbolic link if the input and output use the same protocol and if symbolic links are supported by the protocol. If symbolic link cannot be created, the input file will be copied.

Parameters:

input - input file

output - output file

relativize - relativize the link target path

Throws:

IOException - if an error occurs while copying data or creating the symbolic link
