Method Detail

write

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

Overrides:

write in class java.io.OutputStream

Throws:

java.io.IOException

write

public final void write(int b)
                 throws java.io.IOException

Specified by:

write in class java.io.OutputStream

Throws:

java.io.IOException

complete

public final void complete()
                    throws java.io.IOException

Write out any pending data, including padding if necessary.

Throws:

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

flush

public final void flush()
                 throws java.io.IOException

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.OutputStream

Throws:

java.io.IOException

close

public final void close()
                 throws java.io.IOException

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.OutputStream

Throws:

java.io.IOException

doWrite

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

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

Parameters:

b - a byte array of length 4

Throws:

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

flushBuffer

protected abstract void flushBuffer()
                             throws java.io.IOException

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

Throws:

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

doFlush

protected abstract void doFlush()
                         throws java.io.IOException

Flush the underlying stream, if applicable.

Throws:

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

doClose

protected abstract void doClose()
                         throws java.io.IOException

Close the underlying stream, if applicable.

Throws:

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