Method Detail

readFully

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

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

Throws:

java.io.IOException

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

readFully

public static int readFully(java.io.InputStream in,
                            byte[] b,
                            int off,
                            int len)
                     throws java.io.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:

java.io.IOException

getStreamAsByteArray

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

Returns the contents of the input stream as byte array.

Parameters:

stream - the InputStream

Returns:

the stream content as byte array

Throws:

java.io.IOException

getStreamAsByteArray

public static byte[] getStreamAsByteArray(java.io.InputStream stream,
                                          int length)
                                   throws java.io.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:

java.io.IOException
