Method Detail

write

void write(byte[] b)
    throws IOException

Writes b.length bytes from the specified byte array to this output at the current position.

Parameters:

b - the data.

Throws:

IOException - if an I/O error occurs.

write

void write(byte b)
    throws IOException

Writes 1 byte to this output at the current position.

Parameters:

b - the data.

Throws:

IOException - if an I/O error occurs.

write

void write(ByteBuffer b)
    throws IOException

Writes b.remaining() bytes from the specified byte array to this output at the current position.

Parameters:

b - the data.

Throws:

IOException - if an I/O error occurs.

getPosition

long getPosition()
          throws IOException

gets the current position of the Output. This method is usually used for recording where the data is.
For example, if the Output is a fileOutputStream, then getPosition returns its file position.

Returns:

current position

Throws:

IOException - if an I/O error occurs.

close

void close()
    throws IOException

close the output.

Throws:

IOException - if an I/O error occurs.

wrapAsStream

OutputStream wrapAsStream()
                   throws IOException

convert this TsFileOutput as a outputstream.

Returns:

an output stream whose position is the same with this Output

Throws:

IOException - if an I/O error occurs.

flush

void flush()
    throws IOException

the same with OutputStream.flush().

Throws:

IOException - if an I/O error occurs.

truncate

void truncate(long size)
       throws IOException

The same with FileChannel.truncate(long).

Parameters:

size - size The new size, a non-negative byte count

Throws:

IOException
