Method Detail

write

public void write(byte b,
                  int nbits)
           throws IOException

Writes some bits (max 8) from the specified byte to stream.

Parameters:

b - int which should be written

nbits - bit count to write

Throws:

IOException - if an I/O error occurs

flush

public void flush()
           throws IOException

writes bits from buffer to output stream

Specified by:

flush in interface Flushable

Overrides:

flush in class FilterOutputStream

Throws:

IOException - if I/O error occurs

write

public void write(boolean bit)
           throws IOException

Write a bit to this bit oriented stream.

Parameters:

bit - boolean

Throws:

IOException - DOCUMENT ME!

write

public void write(int bitVect,
                  int length)
           throws IOException

Write an integer as a bit vector of the specified length.

Parameters:

bitVect - int

length - DOCUMENT ME!

Throws:

IOException - DOCUMENT ME!

write

public void write(int b)
           throws IOException

Writes the specified byte to this bit-wise output stream.

The write method of BitOutputStream does nto always cals the write method of its underlying output stream.

Implements the abstract write method of OutputStream.

Overrides:

write in class FilterOutputStream

Parameters:

b - the byte.

Throws:

IOException - if an I/O error occurs.

write

public void write(byte[] b)
           throws IOException

Writes b.length bytes to this output stream.

The write method of FilterOutputStream calls its write method of one argument with the argument b.

Note that this method does not call the one-argument write method of its underlying stream with the single argument b.

Overrides:

write in class FilterOutputStream

Parameters:

b - the data to be written.

Throws:

IOException - if an I/O error occurs.

See Also:

FilterOutputStream.write(byte[], int, int)

write

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

Writes len bytes from the specified byte array starting at offset off to this output stream.

The write method of FilterOutputStream calls the write method of one argument on each byte to output.

Note that this method does not call the write method of its underlying input stream with the same arguments.

Overrides:

write in class FilterOutputStream

Parameters:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

Throws:

IOException - if an I/O error occurs.

FilterOutputStream.write(int)
