Default constructor Construct an empty parallel output stream.

Method Detail

close

public void close()
           throws IOException

Closes this input stream and releases any system resources associated with the stream.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class InputStream

Throws:

IOException

setSeq

public void setSeq(int seq)

set sequence number.

getSeq

public int getSeq()

get sequence number.

read

public int read()
         throws IOException

Reads the next byte of data from the input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of thestream is detected, or an exception is thrown. This read only works if the input stream on the other end sends out one byte of data, otherwise IOException will be thrown. Returns: the next byte of data, or -1 if the end of the stream is reached.

Specified by:

read in class InputStream

Throws:

IOException

read

public int read(byte[] b)
         throws IOException

Reads some number of bytes from the input stream and stores them into the buffer array b. The number of bytes actually read is returned as an integer. This method blocks until input data is available, end of file is detected, or an exception is thrown. If size of b is less than data size from input stream, an IOException will be thrown.

Overrides:

read in class InputStream

Throws:

IOException

read

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

Reads up to len bytes of data from the input stream into an array of bytes. An attempt is made to read as many as len bytes, but a smaller number may be read, possibly zero. The number of bytes actually read is returned as an integer. This method blocks until input data is available, end of file is detected, or an exception is thrown. The parameter len must be larger than the size of data being sent over, or an IOException is thrown.

Overrides:

read in class InputStream

Parameters:

b - - the data.

off - - the start offset in the data.

len - - the maximum number of bytes to read.

Throws:

IOException

readMultiThreaded

protected int readMultiThreaded(byte[] b,
                                int off,
                                int length)
                         throws IOException

Throws:

IOException

readerStatus

public void readerStatus(int pos,
                         boolean stat,
                         int len)

Update reader status by individual reader.

finished

public boolean finished()

Check whether we are finished or not.
