Class BitInputStream

java.lang.Object

com.helger.commons.io.stream.NonBlockingBitInputStream

com.helger.commons.io.stream.BitInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

public class BitInputStream
extends NonBlockingBitInputStream

The BitInputStream allows reading individual bits from a general Java InputStream. Like the various Stream-classes from Java, the BitInputStream has to be created based on another Input stream. It provides a function to read the next bit from the stream, as well as to read multiple bits at once and write the resulting data into an integer value.
For a non-blocking version see NonBlockingBitInputStream.

Constructor Detail

BitInputStream

public BitInputStream(@Nonnull
                      InputStream aIS,
                      @Nonnull
                      ByteOrder aByteOrder)

Create a new bit input stream based on an existing Java InputStream.

Parameters:

aIS - the input stream this class should read the bits from. May not be null.

aByteOrder - The non-null byte order to use.

Method Detail

readBit

public int readBit()
            throws IOException

Read the next bit from the stream.

Overrides:

readBit in class NonBlockingBitInputStream

Returns:

0 if the bit is 0, 1 if the bit is 1.

Throws:

IOException - In case EOF is reached

close

public void close()

Close the underlying input stream.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class NonBlockingBitInputStream
