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
