Enclosing class:
Base64

public static class Base64.OutputStream
extends java.io.FilterOutputStream

A Base64.OutputStream will write data to another OutputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.

Constructor Detail

Base64.OutputStream

public Base64.OutputStream(java.io.OutputStream out)
Constructs a Base64.OutputStream in ENCODE mode.

Parameters:
out - the OutputStream to which data will be written.

Base64.OutputStream

public Base64.OutputStream(java.io.OutputStream out,
                           boolean encode)
Constructs a Base64.OutputStream in either ENCODE or DECODE mode.

Parameters:
out - the OutputStream to which data will be written.
encode - Conversion direction

Base64.ENCODE, Base64.DECODE

Base64.OutputStream

public Base64.OutputStream(java.io.OutputStream out,
                           boolean encode,
                           boolean breakLines)
Constructs a Base64.OutputStream in either ENCODE or DECODE mode.

Parameters:
out - the OutputStream to which data will be written.
encode - Conversion direction
breakLines - Break lines to be less than 80 characters.

Base64.ENCODE, Base64.DECODE
Method Detail

write

public void write(int theByte)
           throws java.io.IOException
Writes the byte to the output stream after converting to/from Base64 notation. When encoding, bytes are buffered three at a time before the output stream actually gets a write() call. When decoding, bytes are buffered four at a time.

Parameters:
theByte - the byte to write
Throws:
java.io.IOException

write

public void write(byte[] theBytes,
                  int off,
                  int len)
           throws java.io.IOException
Calls write(int) repeatedly until len bytes are written.

Parameters:
theBytes - array from which to read bytes
off - offset for array
len - max number of bytes to read into array
Throws:
java.io.IOException

flush

public void flush()
           throws java.io.IOException
Appropriately pads Base64 notation when encoding or throws an exception if Base64 input is not properly padded when decoding.

Throws:
java.io.IOException

close

public void close()
           throws java.io.IOException
Flushes and closes (I think, in the superclass) the stream.

Throws:
java.io.IOException
