Class Base64.OutputStream

java.lang.Object
  java.io.OutputStream
      java.io.FilterOutputStream
          org.dbunit.util.Base64.OutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

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.

Since:

1.3

Base64, FilterOutputStream

Field Summary

out

Constructor Summary

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

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

Method Summary

void	close() Flushes and closes stream.
void	flush() Appropriately pads Base64 notation when encoding or throws an exception if Base64 input is not properly padded when decoding.
void	write(byte[] theBytes, int off, int len) Calls write(int) repeatedly until len bytes are written.
void	write(int theByte) Writes the byte to the output stream after converting to/from Base64 notation.

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.

Since:

1.3

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

Since:

1.3

See Also:

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.

Overrides:

write in class java.io.FilterOutputStream

Parameters:

theByte - the byte to write

Throws:

java.io.IOException

Since:

1.3

write

public void write(byte[] theBytes,
                  int off,
                  int len)
           throws java.io.IOException

Calls write(int) repeatedly until len bytes are written.

Overrides:

write in class java.io.FilterOutputStream

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

Since:

1.3

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.

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.FilterOutputStream

Throws:

java.io.IOException

Since:

1.3

close

public void close()
           throws java.io.IOException

Flushes and closes stream.

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.FilterOutputStream

Throws:

java.io.IOException

Since:

1.3
