Method Detail

transfer

public static void transfer(InputStream in,
                            OutputStream out)
                     throws IOException

Transfers the contents of the given input stream to the given output stream. This implementation uses a large shared buffer and is therefore single-threaded.

Parameters:

in - The input stream.

out - The output stream.

Throws:

IOException - If an error occurs.

toString

public static String toString(InputStream in)
                       throws IOException

Reads the contents of the given input stream as a UTF8 string.

Parameters:

in - The input stream.

Returns:

The string.

Throws:

IOException - If an error occurs.

toString

public static String toString(ByteArrayOutputStream out)

Reads the contents of the given output stream as a UTF8 string.

Parameters:

out - The output stream.

Returns:

The string.

toPrintStream

public static PrintStream toPrintStream(OutputStream out,
                                        boolean autoFlush)

Wraps the given output stream as a PrintStream that uses UTF8 encoding.

Parameters:

out - The stream to wrap.

autoFlush - true If stream should flush on each line.

Returns:

The stream.

toLines

public static List<String> toLines(InputStream in)
                            throws IOException

Reads the contents of the given input stream as a list of UTF8 lines.

Parameters:

in - The input stream.
