Enclosing class:

Base64

public static class Base64.InputStream
extends FilterInputStream

A Base64.InputStream will read data from another java.io.InputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.

Constructor and Description
Base64.InputStream(InputStream in) Constructs a Base64.InputStream in DECODE mode.
Base64.InputStream(InputStream in, int options) Constructs a Base64.InputStream in either ENCODE or DECODE mode.

Modifier and Type	Method and Description
int	read() Reads enough of the input stream to convert to/from Base64 and returns the next byte.
int	read(byte[] dest, int off, int len) Calls Base64.InputStream.read() repeatedly until the end of stream is reached or len bytes are read.

Constructor Detail

Base64.InputStream

public Base64.InputStream(InputStream in)

Constructs a Base64.InputStream in DECODE mode.

Parameters:

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

Since:

1.3

Base64.InputStream

public Base64.InputStream(InputStream in,
                  int options)

Constructs a Base64.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 Base64.InputStream( in, Base64.DECODE )

Parameters:

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

options - Specified options

Method Detail

read

public int read()

Reads enough of the input stream to convert to/from Base64 and returns the next byte.

Overrides:

read in class FilterInputStream

Returns:

next byte

Since:

1.3

read

public int read(byte[] dest,
       int off,
       int len)

Calls Base64.InputStream.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 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.
