Constructor Detail

NIOOutputStream

public NIOOutputStream(WritableByteChannel out)

Constructor

Parameters:

out - the channel to write data to.

NIOOutputStream

public NIOOutputStream(WritableByteChannel out,
                       int size)

Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size.

Parameters:

out - the underlying output stream.

size - the buffer size.

Throws:

IllegalArgumentException - if size <= 0.

Method Detail

write

public void write(int b)
           throws IOException

write a byte on to the stream

Specified by:

write in class OutputStream

Parameters:

b - byte to write

Throws:

IOException - if an error occurs while writing the data.

write

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException

write a byte array to the stream

Overrides:

write in class OutputStream

Parameters:

b - the byte buffer

off - the offset into the buffer

len - the length of data to write

Throws:

IOException - if an error occurs while writing the data.

flush

public void flush()
           throws IOException

flush the data to the output stream This doesn't call flush on the underlying OutputStream, because TCP/IP is particularly efficient at doing this itself ....

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

Throws:

IOException - if an error occurs while writing the data.

close

public void close()
           throws IOException

close this stream

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream

Throws:

IOException

checkClosed

protected void checkClosed()
                    throws IOException

Checks that the stream has not been closed

Throws:

IOException

write

protected void write(ByteBuffer data)
              throws IOException

Throws:

IOException

isWriting

public boolean isWriting()

Specified by:

isWriting in interface TimeStampStream

getWriteTimestamp

public long getWriteTimestamp()

Specified by:

getWriteTimestamp in interface TimeStampStream

setEngine

public void setEngine(SSLEngine engine)
