FileChannelBitInBuffered

public FileChannelBitInBuffered(java.nio.channels.FileChannel file,
                                long startByteOffset,
                                byte _bitOffset,

Method Detail

incrByte

protected void incrByte()

Description copied from class: BitFileBuffered.BitInBuffered

Move forward one byte

Overrides:

incrByte in class BitFileBuffered.BitInBuffered

incrByte

protected void incrByte(int i)

Description copied from class: BitFileBuffered.BitInBuffered

Move forward i bytes

Overrides:

incrByte in class BitFileBuffered.BitInBuffered

skipBytes

public void skipBytes(long len)
               throws java.io.IOException

Description copied from class: BitFileBuffered.BitInBuffered

Skip a number of bytes while reading the bit file. After this opteration, getBitOffset() == 0, so use skipBits(int) to get getBitOffset() to desired value.

Specified by:

skipBytes in interface BitIn

Overrides:

skipBytes in class BitFileBuffered.BitInBuffered

Parameters:

len - The number of bytes to skip

Throws:

java.io.IOException - if an I/O error occurs
