Method Detail

read

public int read()
         throws java.io.IOException
Reads enough of the input stream to convert to/from Base64 and returns the next byte.
Overrides:
read in class java.io.FilterInputStream
Returns:
next byte
Since:
1.3

read

public int read(byte[] dest,
                int off,
                int len)
         throws java.io.IOException
Calls read() repeatedly until the end of stream is reached or len bytes are read. Returns number of bytes read into array or -1 if end of stream is encountered.
Overrides:
read in class java.io.FilterInputStream
Parameters:
dest - array to hold values
off - offset for array
len - max number of bytes to read into array
Returns:
bytes read into array or -1 if end of stream is encountered.
