org.dbreplicator.repconsole
Class Base64.InputStream

java.lang.Object
  java.io.InputStream
      java.io.FilterInputStream
          org.dbreplicator.repconsole.Base64.InputStream

All Implemented Interfaces:

java.io.Closeable

Enclosing class:

Base64

public static class Base64.InputStream
extends java.io.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.

Since:

1.3

See Also:

Base64

Constructor Summary

Base64.InputStream(java.io.InputStream in)
Constructs a Base64.InputStream in DECODE mode.

Base64.InputStream(java.io.InputStream in, int options)
Constructs a Base64.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

Base64.InputStream

public Base64.InputStream(java.io.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(java.io.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

Since:

2.0

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

Since:

1.3
