Constructor Detail

WordPair

public WordPair(GenWordPolynomial<C> a,
                GenWordPolynomial<C> b,
                int i,
                int j)

WordPair constructor.

Parameters:

a - word polynomial i.

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)

equals.

Overrides:

equals in class java.lang.Object

Parameters:

ob - an Object.

Returns:

true if this is equal to o, else false.

compareTo

public int compareTo(WordPair p)

compareTo used in TreeMap // not used at moment. Comparison is based on the number of the pairs.

Specified by:

compareTo in interface java.lang.Comparable<C extends RingElem<C>>

Parameters:

p - a WordPair.

Returns:
