Method Detail

toByteArray

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

Reads the input stream and returns its contents as a byte array.

Parameters:

in - the input stream to read from.

Returns:

the byte array

Throws:

IOException - if an I/O error occurs

copy

public static long copy(InputStream input,
                        OutputStream output)
                 throws IOException

Copies all the contents from the given input stream to the given output stream.

Parameters:

input - the input stream

output - the output stream

Returns:

the number of bytes that have been copied

Throws:

IOException - if an I/O error occurs

populateBuffer

public static long populateBuffer(InputStream in,
                                  byte[] buffer)
                           throws IOException

Populates the given buffer with data read from the input stream. If the data doesn't fit the buffer, only the data that fits in the buffer is read. If the data is less than fits in the buffer, the buffer is not completely filled.

Parameters:

in - the input stream to read from

buffer - the buffer to fill

Returns:

the number of bytes written to the buffer

Throws:

IOException - if an I/O error occurs

closeQuietly

public static void closeQuietly(Closeable closeable)

Null safe close of the given Closeable suppressing any exception.

Parameters:

closeable - to be closed
