NullOutputByteStream

public NullOutputByteStream()

Only for internal engineering use. This api can change without notice.

Method Details

write

public void write(int b)
           throws IOException

Only for internal engineering use. This api can change without notice.

Specified by:

write in interface OutputByteStream

Throws:

IOException

write

public void write(byte[] bytes,
 int offset,
 int length)
           throws IOException

Description copied from interface: OutputByteStream

Only for internal engineering use. This api can change without notice. Write an array of bytes starting at the current position. The position is incremented by the length of the array that has been written.

Specified by:

write in interface OutputByteStream

Parameters:

bytes - The source array.

offset - The offset in the byte array to begin writing from.

length - The number of bytes to write.

Throws:

IOException

length

public long length()
            throws IOException

Description copied from interface: OutputByteStream

Only for internal engineering use. This api can change without notice. The number of bytes that can exist in this OutputByteStream.

Returns:

Total number of bytes available in this OutputByteStream.

Throws:

IOException

close

public void close()
           throws IOException

Description copied from interface: OutputByteStream

Only for internal engineering use. This api can change without notice.

Throws:

IOException

flush

public void flush()
           throws IOException

Description copied from interface: OutputByteStream

Only for internal engineering use. This api can change without notice.

Throws:

IOException

write

public void write(byte[] bytes)
           throws IOException

Description copied from interface: OutputByteStream

Only for internal engineering use. This api can change without notice. Write an array of bytes starting at the current position. The position is incremented by the length of the array that has been written.

Specified by:

write in interface OutputByteStream

Parameters:

bytes - The source array.

Throws:

IOException

seek

public OutputByteStream seek(long position)
                      throws IOException

Only for internal engineering use. This api can change without notice. Set the current position in the underlying data.

Specified by:

seek in interface OutputByteStream

Parameters:

position - Where to set the current position.

Returns:

This object.

Throws:

IOException

getPosition

public long getPosition()
                 throws IOException

Description copied from interface: OutputByteStream

Only for internal engineering use. This api can change without notice. Get the current position.

Specified by:

getPosition in interface OutputByteStream

Returns:

The current position.

Throws:

IOException

eof

public boolean eof()
            throws IOException

Description copied from interface: OutputByteStream

Only for internal engineering use. This api can change without notice. Is the current position of this OutputByteStream at or beyond the end of the underlying data.

Specified by:

eof in interface OutputByteStream

Returns:

True if the current position is beyond the end of the underlying data, false otherwise.

Throws:

IOException

toOutputStream

public SkippingOutputStream toOutputStream()
                                    throws IOException

Description copied from interface: OutputByteStream

This will return a new OutputStream that wraps the same bytes as the OutputByteStream. Writing to or positioning either one will affect the other. This OutputStream may be safely closed without that causing the OutputByteStream to be closed. This is commonly used for external libraries that need an OutputStream. Do NOT use it to pass data around internally as this will generally be inefficient and cause conversion and memory usage.

Specified by:

toOutputStream in interface OutputByteStream

Returns:

an OutputStream that wraps the same bytes

Throws:

IOException

closeAndConvert

public InputByteStream closeAndConvert()
                                throws IOException

Description copied from interface: OutputByteStream

Only for internal engineering use. This api can change without notice.

Specified by:

closeAndConvert in interface OutputByteStream

Throws:

IOException
