Constructor.

Parameters:

buffer - the buffer to append 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

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

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
