Method Detail

values

public static IOTools[] 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 (IOTools c : IOTools.values())
    System.out.println(c);

Returns:

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

valueOf

public static IOTools valueOf(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:

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

NullPointerException - if the argument is null

shallowDeleteDirWithFiles

public static boolean shallowDeleteDirWithFiles(String directory)
                                         throws IORuntimeException

Throws:

IORuntimeException

shallowDeleteDirWithFiles

public static boolean shallowDeleteDirWithFiles(File dir)
                                         throws IORuntimeException

Throws:

IORuntimeException

deleteDirWithFiles

public static boolean deleteDirWithFiles(String dir,
                                         int maxDepth)
                                  throws IORuntimeException

Throws:

IORuntimeException

deleteDirWithFiles

public static boolean deleteDirWithFiles(File dir,
                                         int maxDepth)
                                  throws IORuntimeException

Throws:

IORuntimeException

readFile

public static byte[] readFile(String name)
                       throws IOException

This method first looks for the file in the classpath. If this is not found it appends the suffix .gz and looks again in the classpath to see if it is present. If it is still not found it looks for the file on the file system. If it not found it appends the suffix .gz and looks again on the file system. If it still not found a FileNotFoundException is thrown.

Parameters:

name - Name of the file

Returns:

A byte[] containing the contents of the file

Throws:

IOException - FileNotFoundException thrown if file is not found

writeFile

public static void writeFile(String filename,
                             byte[] bytes)
                      throws IOException

Throws:

IOException

tempName

public static String tempName(String filename)

clean

public static void clean(ByteBuffer bb)
