extends java.lang.Object

Method Summary

static int	readFully(java.io.InputStream in, byte[] b) Helper method, just calls readFully(in, b, 0, b.length)
static int	readFully(java.io.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.
static byte[]	toByteArray(java.io.InputStream stream) Reads all the data from the input stream, and returns the bytes read.

Method Detail

toByteArray

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

Reads all the data from the input stream, and returns the bytes read.

Throws:

java.io.IOException

readFully

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

Helper method, just calls readFully(in, b, 0, b.length)

Throws:

java.io.IOException

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.

If the end of file is reached before any bytes are read, returns -1. If the end of the file is reached after some bytes are read, returns the number of bytes read. If the end of the file isn't reached before len bytes have been read, will return len bytes.

Throws:

java.io.IOException
