Class BitOutputStream

java.lang.Object

com.helger.commons.io.stream.NonBlockingBitOutputStream

com.helger.commons.io.stream.BitOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class BitOutputStream
extends NonBlockingBitOutputStream

The BitOutputStream allows writing individual bits to a general Java OutputStream. Like the various Stream-classes from Java, the BitOutputStream has to be created based on another OutputStream. This class is able to write a single bit to a stream (even though a byte has to be filled until the data is flushed to the underlying output stream). It is also able to write an integer value to the stream using the specified number of bits.
For a non-blocking version see NonBlockingBitOutputStream.

Constructor Detail

BitOutputStream

public BitOutputStream(@Nonnull
                       OutputStream aOS,
                       @Nonnull
                       ByteOrder aByteOrder)

Create a new bit output stream based on an existing Java OutputStream.

Parameters:

aOS - the output stream this class should use. May not be null.

aByteOrder - The non-null byte order to use.

Method Detail

writeBit

public void writeBit(int aBit)
              throws IOException

Write a single bit to the stream. It will only be flushed to the underlying OutputStream when a byte has been completed or when flush() manually.

Overrides:

writeBit in class NonBlockingBitOutputStream

Parameters:

aBit - 1 if the bit should be set, 0 if not

Throws:

IOException - In case writing to the output stream failed

flush

public void flush()
           throws IOException

Write the current cache to the stream and reset the buffer.

Specified by:

flush in interface Flushable

Overrides:

flush in class NonBlockingBitOutputStream

Throws:

IOException - In case writing to the output stream failed

close

public void close()

Flush the data and close the underlying output stream.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class NonBlockingBitOutputStream
