Base64Util.InputStream

public Base64Util.InputStream(InputStream in)

Constructs a .InputStream in DECODE mode.

Parameters:

in - the java.io.InputStream from which to read data.

Since:

1.3

Base64Util.InputStream

public Base64Util.InputStream(InputStream in,
                      int options)

Constructs a .InputStream in either ENCODE or DECODE mode.

Valid options:

   ENCODE or DECODE: Encode or Decode as data is read.
   DONT_BREAK_LINES: don't break lines at 76 characters
     (only meaningful when encoding)
     Note: Technically, this makes your encoding non-compliant.
 

Example: new org.codelogger.utils.Base64Util .InputStream( in, org.codelogger.utils.Base64Util .DECODE )

Parameters:

in - the java.io.InputStream from which to read data.

options - Specified options

Method Detail

read

public int read()
         throws IOException

Reads enough of the input stream to convert to/from org.codelogger.utils.Base64Util and returns the next byte.

Overrides:

read in class FilterInputStream

Returns:

next byte

Throws:

IOException

Overrides:

read in class FilterInputStream

Parameters:

dest - array to hold values

off - offset for array

len - max number of bytes to read into array
