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

Throws:

java.io.IOException

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.

Throws:

java.io.IOException
