org.jivesoftware.smack.util.Base64.InputStream
- All Implemented Interfaces:
- Closeable
- 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.
- Since:
- 1.3

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. |

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)
<i>Note: Technically, this makes your encoding non-compliant.</i>
Example:
new Base64.InputStream( in, Base64.DECODE )
- Parameters:
in
- the java.io.InputStream from which to read
data.options
- Specified options- Since:
- 2.0
