Package org.apache.commons.codec.binary

Class BaseNCodecOutputStream

java.lang.Object

java.io.OutputStream

java.io.FilterOutputStream

org.apache.commons.codec.binary.BaseNCodecOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

Direct Known Subclasses:

Base32OutputStream, Base64OutputStream

public class BaseNCodecOutputStream
extends java.io.FilterOutputStream

Abstract superclass for Base-N output streams.

To write the EOF marker without closing the stream, call eof() or use an Apache Commons IO CloseShieldOutputStream.

Constructor Detail

BaseNCodecOutputStream

public BaseNCodecOutputStream(java.io.OutputStream out,
                              BaseNCodec basedCodec,
                              boolean doEncode)

Method Detail

write

public void write(int i)
           throws java.io.IOException

Writes the specified byte to this output stream.

Overrides:

write in class java.io.FilterOutputStream

Parameters:

i - source byte

Throws:

java.io.IOException - if an I/O error occurs.

write

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

Writes len bytes from the specified b array starting at offset to this output stream.

Overrides:

write in class java.io.FilterOutputStream

Parameters:

b - source byte array

offset - where to start reading the bytes

len - maximum number of bytes to write

Throws:

java.io.IOException - if an I/O error occurs.

java.lang.NullPointerException - if the byte array parameter is null

java.lang.IndexOutOfBoundsException - if offset, len or buffer size are invalid

flush

private void flush(boolean propagate)
            throws java.io.IOException

Flushes this output stream and forces any buffered output bytes to be written out to the stream. If propagate is true, the wrapped stream will also be flushed.

Parameters:

propagate - boolean flag to indicate whether the wrapped OutputStream should also be flushed.

Throws:

java.io.IOException - if an I/O error occurs.

flush

public void flush()
           throws java.io.IOException

Flushes this output stream and forces any buffered output bytes to be written out to the stream.

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.FilterOutputStream

Throws:

java.io.IOException - if an I/O error occurs.

close

public void close()
           throws java.io.IOException

Closes this output stream and releases any system resources associated with the stream.

To write the EOF marker without closing the stream, call eof() or use an Apache Commons IO CloseShieldOutputStream.

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.FilterOutputStream

Throws:

java.io.IOException - if an I/O error occurs.

eof

public void eof()
         throws java.io.IOException

Writes EOF.

Throws:

java.io.IOException - if an I/O error occurs.
