org.dbunit.util.Base64.OutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

Enclosing class:

Base64

public static class Base64.OutputStream
extends 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	Description
OutputStream(OutputStream out)	Constructs a Base64.OutputStream in ENCODE mode.
OutputStream(OutputStream out, boolean encode)	Constructs a Base64.OutputStream in either ENCODE or DECODE mode.

Method Summary

Modifier and Type	Method	Description
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 Details

OutputStream

public OutputStream(OutputStream out)

Constructs a Base64.OutputStream in ENCODE mode.

Parameters:

out - the OutputStream to which data will be written.

Since:

1.3

OutputStream

public OutputStream(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 Details

write

public void write(int theByte)
           throws 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 FilterOutputStream

Parameters:

theByte - the byte to write

Throws:

IOException

Since:

1.3

write

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

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

Overrides:

write in class FilterOutputStream

Parameters:

theBytes - array from which to read bytes

off - offset for array

len - max number of bytes to read into array

Throws:

IOException

Since:

1.3

flush

public void flush()
           throws 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 Flushable

Overrides:

flush in class FilterOutputStream

Throws:

IOException

Since:

1.3

close

public void close()
           throws IOException

Flushes and closes stream.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class FilterOutputStream

Throws:

IOException

Since:

1.3
