Class Base64.InputStream

public static class Base64.InputStream extends FilterInputStream

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

Since: 1.3

See Also: Base64

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

Method Summary
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 read repeatedly until the end of stream is reached or `len` bytes are read.

Constructor Detail

InputStream

public InputStream(InputStream in)

Constructs a InputStream in DECODE mode.

Parameters: in the java.io.InputStream from which to read data.

Since: 1.3

InputStream

public 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 Base64.InputStream( in, Base64.DECODE )

Parameters: in the java.io.InputStream from which to read data. options Specified options

Since: 2.0

Method Detail

read

public int read()

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

Returns: next byte

Since: 1.3

read

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

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.

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.
