Class Base64EncodingOutputStream

java.lang.Object

java.io.OutputStream

org.apache.axiom.util.base64.AbstractBase64EncodingOutputStream

org.apache.axiom.util.base64.Base64EncodingOutputStream

All Implemented Interfaces:

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

public class Base64EncodingOutputStream
extends AbstractBase64EncodingOutputStream

OutputStream implementation that writes base64 encoded data to another OutputStream using ASCII encoding. This class internally buffers the data before writing it to the underlying stream.

Constructor Detail

Base64EncodingOutputStream

public Base64EncodingOutputStream(java.io.OutputStream parent,
                                  int bufferSize)

Constructor.

Parameters:

parent - the stream to write the encoded data to

bufferSize - the buffer size to use

Base64EncodingOutputStream

public Base64EncodingOutputStream(java.io.OutputStream parent)

Constructor that sets the buffer size to its default value of 4096 characters.

Parameters:

parent - the stream to write the encoded data to

Method Detail

doWrite

protected void doWrite(byte[] b)
                throws java.io.IOException

Description copied from class: AbstractBase64EncodingOutputStream

Write base64 encoded data. If necessary, the implementation should accumulate the data in a buffer before writing it to the underlying stream.

Specified by:

doWrite in class AbstractBase64EncodingOutputStream

Parameters:

b - a byte array of length 4

Throws:

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

flushBuffer

protected void flushBuffer()
                    throws java.io.IOException

Description copied from class: AbstractBase64EncodingOutputStream

Write any pending data to the underlying stream, if applicable. Note that implementations should not flush the underlying stream.

Specified by:

flushBuffer in class AbstractBase64EncodingOutputStream

Throws:

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

doFlush

protected void doFlush()
                throws java.io.IOException

Description copied from class: AbstractBase64EncodingOutputStream

Flush the underlying stream, if applicable.

Specified by:

doFlush in class AbstractBase64EncodingOutputStream

Throws:

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

doClose

protected void doClose()
                throws java.io.IOException

Description copied from class: AbstractBase64EncodingOutputStream

Close the underlying stream, if applicable.

Specified by:

doClose in class AbstractBase64EncodingOutputStream

Throws:

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