b - word polynomial j.

i - first index.

j - second index.

Method Detail

toString

public java.lang.String toString()

toString.

Overrides:

toString in class java.lang.Object

pairNumber

public void pairNumber(int n)

Set removed pair number.

Parameters:

n - number of this pair generated in OrderedPairlist.

getPairNumber

public int getPairNumber()

Get removed pair number.

Returns:

n number of this pair generated in OrderedPairlist.

equals

public boolean equals(java.lang.Object ob)
