Method Detail

values

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

Returns:

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

valueOf

public static FileCopyUtils 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

copyToString

public static String copyToString(Reader in)
                           throws IOException

Copy the contents of the given Reader into a String. Closes the reader when done.

Parameters:

in - the reader to copy from

Returns:

the String that has been copied to

Throws:

IOException - in case of I/O errors

copyToByteArray

public static byte[] copyToByteArray(InputStream in)
                              throws IOException

Copy the contents of the given InputStream into a new byte array. Closes the stream when done.

Parameters:

in - the stream to copy from

Returns:

the new byte array that has been copied to

Throws:

IOException - in case of I/O errors

copyToString

public static String copyToString(InputStream in,
                                  Charset encoding)
                           throws IOException

Copy the contents of the given InputStream into a new String based on this encoding. Closes the stream when done.

Parameters:

in - the stream to copy from

encoding - The encoding to use.

Returns:

The new String.

Throws:

IOException - in case of I/O errors

copy

public static void copy(Reader in,
                        Writer out)
                 throws IOException

Copy the contents of the given Reader to the given Writer. Closes both when done.

Parameters:

in - the Reader to copy from

out - the Writer to copy to

Throws:

IOException - in case of I/O errors

copy

public static int copy(InputStream in,
                       OutputStream out)
                throws IOException

Copy the contents of the given InputStream to the given OutputStream. Closes both streams when done.

Parameters:

in - the stream to copy from

out - the stream to copy to

Returns:

the number of bytes copied

Throws:

IOException - in case of I/O errors
