ByteArrayEndPoint

public ByteArrayEndPoint()

ByteArrayEndPoint

public ByteArrayEndPoint(byte[] input,
                         int outputSize)

Method Detail

isNonBlocking

public boolean isNonBlocking()

Returns:

the nonBlocking

setNonBlocking

public void setNonBlocking(boolean nonBlocking)

Parameters:

nonBlocking - the nonBlocking to set

getIn

public ByteArrayBuffer getIn()

Returns:

Returns the in.

setIn

public void setIn(ByteArrayBuffer in)

Parameters:

in - The in to set.

getOut

public ByteArrayBuffer getOut()

Returns:

Returns the out.

setOut

public void setOut(ByteArrayBuffer out)

Parameters:

out - The out to set.

isOpen

public boolean isOpen()

Specified by:

isOpen in interface EndPoint

isBlocking

public boolean isBlocking()

Specified by:

isBlocking in interface EndPoint

blockReadable

public boolean blockReadable(long millisecs)

Specified by:

blockReadable in interface EndPoint

blockWritable

public boolean blockWritable(long millisecs)

Specified by:

blockWritable in interface EndPoint

close

public void close()
           throws IOException

Description copied from interface: EndPoint

Close any backing stream associated with the buffer

Specified by:

close in interface EndPoint

Throws:

IOException

fill

public int fill(Buffer buffer)
         throws IOException

Description copied from interface: EndPoint

Fill the buffer from the current putIndex to it's capacity from whatever byte source is backing the buffer. The putIndex is increased if bytes filled. The buffer may chose to do a compact before filling.

Specified by:

fill in interface EndPoint

Returns:

an int value indicating the number of bytes filled or -1 if EOF is reached.

Throws:

IOException

flush

public int flush(Buffer buffer)
          throws IOException

Description copied from interface: EndPoint

Flush the buffer from the current getIndex to it's putIndex using whatever byte sink is backing the buffer. The getIndex is updated with the number of bytes flushed. Any mark set is cleared. If the entire contents of the buffer are flushed, then an implicit empty() is done.

Specified by:

flush in interface EndPoint

Parameters:

buffer - The buffer to flush. This buffers getIndex is updated.

Returns:

the number of bytes written

Throws:

IOException

flush

public int flush(Buffer header,
                 Buffer buffer,
                 Buffer trailer)
          throws IOException

Description copied from interface: EndPoint

Flush the buffer from the current getIndex to it's putIndex using whatever byte sink is backing the buffer. The getIndex is updated with the number of bytes flushed. Any mark set is cleared. If the entire contents of the buffer are flushed, then an implicit empty() is done. The passed header/trailer buffers are written before/after the contents of this buffer. This may be done either as gather writes, as a poke into this buffer or as several writes. The implementation is free to select the optimal mechanism.

Specified by:

flush in interface EndPoint

Parameters:

header - A buffer to write before flushing this buffer. This buffers getIndex is updated.

buffer - The buffer to flush. This buffers getIndex is updated.

trailer - A buffer to write after flushing this buffer. This buffers getIndex is updated.

Returns:

the total number of bytes written.

Throws:

IOException

reset

public void reset()

getLocalAddr

public String getLocalAddr()

Specified by:

getLocalAddr in interface EndPoint

Returns:

The local IP address to which this EndPoint is bound, or null if this EndPoint does not represent a network connection.

getLocalHost

public String getLocalHost()

Specified by:

getLocalHost in interface EndPoint

Returns:

The local host name to which this EndPoint is bound, or null if this EndPoint does not represent a network connection.

getLocalPort

public int getLocalPort()

Specified by:

getLocalPort in interface EndPoint

Returns:

The local port number on which this EndPoint is listening, or 0 if this EndPoint does not represent a network connection.

getRemoteAddr

public String getRemoteAddr()

Specified by:

getRemoteAddr in interface EndPoint

Returns:

The remote IP address to which this EndPoint is connected, or null if this EndPoint does not represent a network connection.

getRemoteHost

public String getRemoteHost()

Specified by:

getRemoteHost in interface EndPoint

Returns:

The host name of the remote machine to which this EndPoint is connected, or null if this EndPoint does not represent a network connection.

getRemotePort

public int getRemotePort()

Specified by:

getRemotePort in interface EndPoint

Returns:

The remote port number to which this EndPoint is connected, or 0 if this EndPoint does not represent a network connection.

getTransport

public Object getTransport()

Specified by:

getTransport in interface EndPoint

Returns:

The underlying transport object (socket, channel, etc.)

flush

public void flush()
