Constructor Detail

MuxInputStream

MuxInputStream(Mux mux,
               Session session,
               Object sessionLock)

Method Detail

down

void down(IOException e)

appendToBufQueue

void appendToBufQueue(ByteBuffer data)

read

public int read()
         throws IOException

Specified by:

read in class InputStream

Throws:

IOException

wrap

private IOException wrap(String message,
                         Exception e)

read

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

Overrides:

read in class InputStream

Throws:

IOException

checkInboundRation

private void checkInboundRation()

Sends ration increment, if read drained buffers below a certain mark. This method must NOT be invoked if the inbound ration in infinite, and it must ONLY be invoked while synchronized on this session's lock. REMIND: The implementation of this action will be a significant area for performance tuning.

available

public int available()
              throws IOException

Overrides:

available in class InputStream

Throws:

IOException

close

public void close()

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class InputStream

isSentAcknowledgment

boolean isSentAcknowledgment()

Returns:

the sentAcknowledgment

getBufRemaining

int getBufRemaining()

Returns:

the inBufRemaining

isClosed

boolean isClosed()

Returns:

the inClosed

setBufRemaining

void setBufRemaining(int inBufRemaining)

Parameters:

inBufRemaining - the inBufRemaining to set

setEOF

void setEOF(boolean inEOF)

Parameters:

inEOF - the inEOF to set
