public class IOUtils
extends Object

Utility class containing IO helper methods

Method Summary

static byte[]	getStreamAsByteArray(InputStream stream) Returns the contents of the input stream as byte array.
static byte[]	getStreamAsByteArray(InputStream stream, int length) Returns the contents of the input stream as byte array.
static int	readFully(InputStream in, byte[] b) Reads into a byte array.
static int	readFully(InputStream in, byte[] b, int off, int len) Same as the normal in.read(b, off, len), but tries to ensure that the entire len number of bytes is read.

Method Detail

readFully

public static int readFully(InputStream in,
                            byte[] b)
                     throws IOException

Reads into a byte array. Ensures that the full buffer is read. Helper method, just calls readFully(in, b, 0, b.length)

Throws:

IOException

readFully(java.io.InputStream, byte[], int, int)

readFully

public static int readFully(InputStream in,
                            byte[] b,
                            int off,
                            int len)
                     throws IOException

Same as the normal in.read(b, off, len), but tries to ensure that the entire len number of bytes is read.

Returns:

Returns the number of bytes read, or -1 if the end of file is reached before any bytes are read

Throws:

IOException

getStreamAsByteArray

public static byte[] getStreamAsByteArray(InputStream stream)
                                   throws IOException

Returns the contents of the input stream as byte array.

Parameters:

stream - the InputStream

Returns:

the stream content as byte array

Throws:

IOException

getStreamAsByteArray

public static byte[] getStreamAsByteArray(InputStream stream,
                                          int length)
                                   throws IOException

Returns the contents of the input stream as byte array.

Parameters:

stream - the InputStream

length - the number of bytes to copy, if length < 0, the number is unlimited

Returns:

the stream content as byte array

Throws:

IOException
