This class represents sequences of bit pairs, and does conversions and comparisons. Provided as is for CS420.
bitPairSeq
public bitPairSeq(int len);
len
- the length of the bit pair sequence to be created
public bitPairSeq(byte[] B);
B
- the byte array from which the bit pair sequence will be created
public void appendBP(bitPair bp)
bp
- the bit pair to be appended to the sequence. (The current position is advanced.)
public void changeBP(bitPair bp)
bp
- the bit pair to replace the current pair in the sequence. (The current position is advanced.)
public void insertBP(bitPair bp)
bp
- the bit pair to be inserted after the current pair in the sequence. (The current position is advanced.)
public boolean isAt(int pos)
pos
- the position to be tested for currency in the sequence. (?==pos + 1)
Pos==pos + 1.
public boolean isBefore(int pos)
pos
- the position to be tested for currency in the sequence. (?<=pos)
Pos<=pos.
public bitPair nextBP()
public boolean wasLastBP()
public void zeroBPS(int len)
4*len bit pairs of the sequence to zero.
len
- the number of bytes to be zeroed.
